Search Engine Optimization

Search engines are one of the primary ways that Internet users find web sites. That's why a web site with good search engine listings may see a dramatic increase in traffic. According to a survey, more than 70% traffic on the websites come through search engines.
Everyone wants good listings in search engines, search results. Unfortunately, many web sites appear poorly in search engine rankings or may not be listed at all because they fail to consider how search engines work. Actually they do not know how to get listed in search results.

In particular, submitting to search engines is only part of the challenge of getting good search engine positioning. It's also important to prepare a web site through "search engine optimization."

Search engine optimization means ensuring that your web pages are accessible to search engines (the crawlers and spiders) and focused in ways that help improve the chances they will be found by the crawlers and spiders.

The term " search engine " is often used generically to describe both crawler-based search engines and human-powered directories. These two types of search engines gather their listings in radically different ways.

Search Engines based on crawlers

Crawler-based search engines, such as Google (http://www.google.com) , create their listings automatically. They "crawl" or "spider" the web, then people search through what they have found.

If you change your web pages, crawler-based search engines eventually find these changes, and that can affect how you are listed. Page titles, body copy and other elements all play a role.

Human-edited Directories

A human-powered directory, such as the Open Directory (http://www.dmoz.org), depends on humans for its listings. You submit a short description to the directory for your entire site, or editors write one for sites they review. A search looks for matches only in the descriptions submitted.

Changing your web pages has no effect on your listing. Things that are useful for improving a listing with a search engine have nothing to do with improving a listing in a directory. The only exception is that a good site, with good content, might be more likely to get reviewed for free than a poor site.

Search Engines with mixed results

In the web's early days, it used to be that a search engine either presented crawler-based results or human-powered listings. Today, it extremely common for both types of results to be presented. Usually, a hybrid search engine will favor one type of listings over another. For example, MSN Search is more likely to present human-powered listings from LookSmart. However, it does also present crawler-based results (as provided by Inktomi), especially for more obscure queries.

Constituents of Crawler-Based Search Engine

Crawler-based search engines have three major elements. First is the spider, also called the crawler. The spider visits a web page, reads it, and then follows links to other pages within the site. This is what it means when someone refers to a site being "spidered" or "crawled." The spider returns to the site on a regular basis, such as every month or two, to look for changes.

Everything the spider finds goes into the second part of the search engine, the index. The index, sometimes called the catalog, is like a giant book containing a copy of every web page that the spider finds. If a web page changes, then this book is updated with new information.

Sometimes it can take a while for new pages or changes that the spider finds to be added to the index. Thus, a web page may have been "spidered" but not yet "indexed." Until it is indexed -- added to the index -- it is not available to those searching with the search engine.

Search engine software is the third part of a search engine. This is the program that sifts through the millions of pages recorded in the index to find matches to a search and rank them in order of what it believes is most relevant.

Major Search Engines:

All crawler-based search engines have the basic parts described above, but there are differences in how these parts are tuned. That is why the same search on different search engines often produces different results.

Search for anything using your favorite crawler-based search engine. Nearly instantly, the search engine will sort through the millions of pages it knows about and present you with ones that match your topic. The matches will even be ranked, so that the most relevant ones come first.

Of course, the search engines don't always get it right. Non-relevant pages make it through, and sometimes it may take a little more digging to find what you are looking for. But, by and large, search engines do an amazing job.

As WebCrawler founder Brian Pinkerton puts it, "Imagine walking up to a librarian and saying, 'travel.' They’re going to look at you with a blank face."

OK -- a librarian's not really going to stare at you with a vacant expression. Instead, they're going to ask you questions to better understand what you are looking for.

Unfortunately, search engines don't have the ability to ask a few questions to focus your search, as a librarian can. They also can't rely on judgment and past experience to rank web pages, in the way humans can.

So, how do crawler-based search engines go about determining relevancy, when confronted with hundreds of millions of web pages to sort through? They follow a set of rules, known as an algorithm. Exactly how a particular search engine's algorithm works is a closely-kept trade secret. However, all major search engines follow the general rules below.

Location and Frequency

One of the main rules in a ranking algorithm involves the location and frequency of keywords on a web page. Call it the location/frequency method, for short.

Remember the librarian mentioned above? They need to find books to match your request of "travel," so it makes sense that they first look at books with travel in the title. Search engines operate the same way. Pages with the search terms appearing in the HTML title tag are often assumed to be more relevant than others to the topic.

Search engines will also check to see if the search keywords appear near the top of a web page, such as in the headline or in the first few paragraphs of text. They assume that any page relevant to the topic will mention those words right from the beginning.

Frequency is the other major factor in how search engines determine relevancy. A search engine will analyze how often keywords appear in relation to other words in a web page. Those with a higher frequency are often deemed more relevant than other web pages.

Spice In The Recipe

Now it's time to qualify the location/frequency method described above. All the major search engines follow it to some degree, in the same way cooks may follow a standard chili recipe. But cooks like to add their own secret ingredients. In the same way, search engines add spice to the location/frequency method. Nobody does it exactly the same, which is one reason why the same search on different search engines produces different results.

To begin with, some search engines index more web pages than others. Some search engines also index web pages more often than others. The result is that no search engine has the exact same collection of web pages to search through. That naturally produces differences, when comparing their results.

Search engines may also penalize pages or exclude them from the index, if they detect search engine "spamming." An example is when a word is repeated hundreds of times on a page, to increase the frequency and propel the page higher in the listings. Search engines watch for common spamming methods in a variety of ways, including following up on complaints from their users.

Off The Page Factors

Crawler-based search engines have plenty of experience now with webmasters who constantly rewrite their web pages in an attempt to gain better rankings. Some sophisticated webmasters may even go to great lengths to "reverse engineer" the location/frequency systems used by a particular search engine. Because of this, all major search engines now also make use of "off the page" ranking criteria.

Off the page factors are those that a webmasters cannot easily influence. Chief among these is link analysis. By analyzing how pages link to each other, a search engine can both determine what a page is about and whether that page is deemed to be "important" and thus deserving of a ranking boost. In addition, sophisticated techniques are used to screen out attempts by webmasters to build "artificial" links designed to boost their rankings.

Another off the page factor is clickthrough measurement. In short, this means that a search engine may watch what results someone selects for a particular search, then eventually drop high-ranking pages that aren't attracting clicks, while promoting lower-ranking pages that do pull in visitors. As with link analysis, systems are used to compensate for artificial links generated by eager webmasters.

A query on a crawler-based search engine often turns up thousands or even millions of matching web pages. In many cases, only the 10 most "relevant" matches are displayed on the first page.

Naturally, anyone who runs a web site wants to be in the "top ten" results. This is because most users will find a result they like in the top ten. Being listed 11 or beyond means that many people may miss your web site.

The tips below will help you come closer to this goal, both for the keywords you think are important and for phrases you may not even be anticipating.

Select your ‘Target Keywords’

How do you think people will search for your web page? The words you imagine them typing into the search box are your target keywords.

For example, say you have a page devoted to stamp collecting. Anytime someone types "stamp collecting," you want your page to be in the top ten results. Then those are your target keywords for that page.

Each page in your web site will have different target keywords that reflect the page's content. For example, say you have another page about the history of stamps. Then "stamp history" might be your keywords for that page.

Your target keywords should always be at least two or more words long. Usually, too many sites will be relevant for a single word, such as "stamps." This "competition" means your odds of success are lower. Don't waste your time fighting the odds. Pick phrases of two or more words, and you'll have a better shot at success.

Place Your Keywords well on your webpage

Make sure your target keywords appear in the crucial locations on your web pages. The page's HTML title tag is most important. Failure to put target keywords in the title tag is the main reason why perfectly relevant web pages may be poorly ranked.

Build your titles around the top two or three phrases that you would like the page to be found for. The titles should be relatively short and attractive. Think of newspaper headlines. With a few words, they make you want to read a story. Similarly, your page titles are like headlines for your pages. They appear in search engine listings, and a short, attractive title may help make users click through to your site.

Keep in mind that tables can "push" your text further down the page, making keywords less relevant because they appear lower on the page. This is because tables break apart when search engines read them. For example, picture a typical two-column page, where the first column has navigational links, while the second column has the keyword loaded text.

Have Relevant Content on your webpage

Changing your page titles is not necessarily going to help your page do well for your target keywords if the page has nothing to do with the topic. Your keywords need to be reflected in the page's content.

In particular, that means you need HTML text on your page. Sometimes sites present large sections of copy via graphics. It looks pretty, but search engines can't read those graphics. That means they miss out on text that might make your site more relevant. Some of the search engines will index ALT text and comment information. But to be safe, use HTML text whenever possible. Some of your human visitors will appreciate it, also.

Be sure that your HTML text is "visible." Some designers try to spam search engines by repeating keywords in a tiny font or in the same color at the background color to make the text invisible to browsers. Search engines are catching on to these and other tricks. Expect that if the text is not visible in a browser, then it may not be indexed by a search engine.

Finally, consider "expanding" your text references, where appropriate. For example, a stamp collecting page might have references to "collectors" and "collecting." Expanding these references to "stamp collectors" and "stamp collecting" reinforces your strategic keywords in a legitimate and natural manner. Your page really is about stamp collecting, but edits may have reduced its relevancy unintentionally.

Avoid Stumbling Blocks

Some search engines see the web the way someone using a very old browser might. They may not read image maps. They may not read frames. You need to anticipate these problems, or a search engine may not index any or all your web pages.

Have HTML links

Often, designers create only image map links from the home page to inside pages. A search engine that can't follow these links won't be able to get "inside" the site. Unfortunately, the most descriptive, relevant pages are often inside pages rather than the home page.

Solve this problem by adding some HTML hyperlinks to the home page that lead to major inside pages or sections of your web site. This is something that will help some of your human visitors, also. Put them down at the bottom of the page. The search engine will find them and follow them.

Also consider making a site map page with text links to everything in your web site. You can submit this page, which will help the search engines locate pages within your web site.

Finally, be sure you do a good job of linking internally between your pages. If you naturally point to different pages from within your site, you increase the odds that search engines will follow links and find more of your web site.

Frames – NO NO

Some of the major search engines cannot follow frame links. Make sure there is an alternative method for them to enter and index your site, either through meta tags or smart design.

Avoid Dynamic pages (go for static ones)

Generating pages via CGI or database-delivery? Expect that some of the search engines won't be able to index them. Consider creating static pages whenever possible, perhaps using the database to update the pages, not to generate them on the fly. Also, avoid symbols in your URLs, especially the ? symbol. Search engines tend to choke on it.

Build Links (have more and more inbound back links)

Every major search engine uses link analysis as part of their ranking algorithms. This is done because its very difficult for webmasters to "fake" good links, in the way they might try to spam search engines by manipulating the words on their web pages. As a result, link analysis gives search engines a useful means of determining which pages are good for particular topics.

By building links, you can help improve how well your pages do in link analysis systems. The key is understanding that link analysis is not about "popularity." In other words, it's not an issue of getting lots of links from anywhere. Instead, you want links from good web pages that are related to the topics you want to be found for.

Here's the simple means to find those good links. Go to the major search engines. Search for your target keywords. Look at the pages that appear in the top results. Now visit those pages and ask the site owners if they will link to you. Not everyone will, especially sites that are extremely competitive with you. However, there will be non-competitive sites that will link to you -- especially if you offer to link back.

Why is this system good? By searching for your target keywords, you'll find the pages that the search engines themselves are telling you are good, as evidenced by the fact that they rank well. Hence, links from these pages are more important -- and important for the terms you are interested in -- than links from other pages. In addition, if these pages are top ranked, then they are likely to be receiving many visitors. Thus, if you can gain links from them, you might receive some visitors who initially go to those pages.

Do not spam your keywords

For one thing, spamming doesn't always work with search engines. It can also backfire. search engines may detect your spamming attempt and penalize or ban your page from their listings.

Also, search engines spamming attempts usually center around being top ranked for extremely popular keywords. You can try and fight that battle against other sites, but then be prepared to spend a lot of time each week, if not each day, defending your ranking. That effort usually would be better spent on networking and alternative forms of publicity, described below.

If those practical reasons aren't enough, how about some ethical ones? The content of most web pages ought to be enough for search engines to determine relevancy without webmasters having to resort to repeating keywords for no reason other than to try and "beat" other web pages. The stakes will simply keep rising, and users will also begin to hate sites that undertake these measures.

Consider search engine spamming against spam mail. No one likes spam mail, and sites that use spam mail services often face a backlash from those on the receiving end. Sites that spam search engines degrade the value of search engine listings. As the problem grows, these sites may face the same backlash that spam mail generates.

Submit all of Your Key Pages

Most search engines will index the other pages from your web site by following links from a page you submit to them. But sometimes they miss, so it's good to submit the top two or three pages that best summarize your web site.

Don't trust the submission process to automated programs and services. Some of them are excellent, but the major search engines are too important. There aren't that many, so submit manually, so that you can see if there are any problems reported.

Also, don't bother submitting more than the top two or three pages. It doesn't speed up the process. Submitting alternative pages is only insurance. In case the search engine has trouble reaching one of the pages, you've covered yourself by giving it another page from which to begin its crawl of your site.

Be patient. It can take up to a month to two months for your "non-submitted" pages to appear in a search engine, and some search engines may not list every page from your site.

Periodically Verify and Maintain Your Listing

Once your pages are listed in a search engine, monitor your listing every week or two. Strange things happen. Pages disappear from catalogs. Links go screwy. Watch for trouble, and resubmit if you spot it.

Resubmit your site any time you make significant changes. Search engines should revisit on a regular schedule. However, some search engines have grown smart enough to realize some sites only change content once or twice a year, so they may visit less often. Resubmitting after major changes will help ensure that your site's content is kept current.

Beyond Search Engines

It's worth taking the time to make your site more search engines friendly, because some simple changes may pay off with big results. Even if you don't come up in the top ten for your target keywords, you may find an improvement for target keywords you aren't anticipating. The addition of just one extra word can suddenly make a site appear more relevant, and it can be impossible to guess what that word will be.

Also, remember that while search engines are a primary way people look for web sites, but they are not the only way. People also find sites through word-of-mouth, traditional advertising, the traditional media, newsgroup postings, web directories and links from other sites. Many times, these alternative forms are far more effective draws than are search engines.

Finally, know when it's time to call it quits. A few changes may be enough to make you tops in one or two search engines. But that's not enough for some people, and they will invest days creating special pages and changing their sites to try and do better. This time could usually be put to better use pursuing non-search engine publicity methods.

Don't obsess over your ranking. Even if you follow every tip and find no improvement, you still have gained something. You will know that search engines are not the way you'll be attracting traffic. You can concentrate your efforts in more productive areas, rather than wasting your valuable time.

How To Use HTML Meta Tags

Want to get a top ranking in search engines? No problem! All you need to do is add a few magical "meta tags" to your web pages, and you'll skyrocket to the top of the listings.

If only it were so easy. Let's make it clear:

· Meta tags are not a magic solution.

·Meta tags are not a magic solution.

·Meta tags are not a magic solution.

Meta tags have never been a guaranteed way to gain a top ranking on crawler-based search engines. Today, the most valuable feature they offer the web site owner is the ability to control to some degree how their web pages are described by some search engines. They also offer the ability to prevent pages from being indexed at all. This page explores these and other meta tag-related features in more depth.

Meta Tag Overview
What are Meta Tag? They are information inserted into the "head" area of your web pages. Other than the title tag (explained below), information in the head area of your web pages is not seen by those viewing your pages in browsers. Instead, meta information in this area is used to communicate information that a human visitor may not be concerned with. Meta Tag, for example, can tell a browser what "character set" to use or whether a web page has self-rated itself in terms of adult content.

Let's see two common types of meta tags, then we'll discuss exactly how they are used in more depth:

<HEAD>
<TITLE>Search engine optimization </TITLE>
<META name="description" content="I am a person involved in search engine optimization.">
<META name="keywords" content="SEO, Search, search engine, website optimization, website promotion">
</HEAD>

In the example above, you can see the beginning of the page's "head" area as noted by the HEAD tag -- it ends at the portion shown as /HEAD.

Meta tags go in between the "opening" and "closing" HEAD tags. Shown in the example is a TITLE Tag, then a META DESCRIPTION tag, then a META KEYWORDS tag. Let's talk about what these do.

The Title Tag

The HTML title tag isn't really a meta tag, but it's worth discussing in relation to them. Whatever text you place in the title tag (between the TITLE and /TITLE portions as shown in the example) will appear in the reverse bar of someone's browser when they view the web page.

The Meta Description Tag

The meta description tag allows you to influence the description of your page in the crawlers that support the tag.

Look back at the example of a meta tag. See the first meta tag shown, the one that says "name=description"? That's the meta description tag. The text you want to be shown as your description goes between the quotation marks after the "content=" portion of the tag (generally, 200 to 250 characters may be indexed, though only a smaller portion of this amount may be displayed).

The Meta Keywords Tag

The meta keywords tag allows you to provide additional text for crawler-based search engines to index along with your body copy. How does this help you? Well, for most major crawlers, it doesn't. That's because most crawlers now ignore the tag.

The meta keywords tag is sometimes useful as a way to reinforce the terms you think a page is important for ON THE FEW CRAWLERS THAT SUPPORT IT. For instance, if you had a page about stamp collecting -- AND you say the words stamp collecting at various places in your body copy -- then mentioning the words "stamp collecting" in the meta keywords tag MIGHT help boost your page a bit higher for those words.

Remember, if you don't use the words "stamp collecting" on the page at all, then just adding them to the meta keywords tag is extremely unlikely to help the page do well for the term. The text in the meta keywords tag, FOR THE FEW CRAWLERS THAT SUPPORT IT, works in conjunction with the text in your body copy.

The meta keyword tag is also sometimes useful as a way to help your page come up for synonyms or unusual words that don't appear on the page itself. For instance, let's say you had a page all about the "Penny Black" stamp. You never actually say the word "collecting" on this page. By having the word in your meta keywords tag, then you may help increase the odds of coming up if someone searched for "penny black stamp collecting." Of course you would greater increase the odds if you just used the word "collecting" in the body copy of the page itself.

Here's another example. Let's say you have a page about horseback riding, and you've written your page using "horseback" as a single word. You realize that some people may instead search for "horse back riding," with "horse back" in their searches being two separate words. If you listed these words separately in your meta keywords tag, THEN MAYBE FOR THE FEW CRAWLERS THAT SUPPORT IT, your page might rank better for "horse back" riding. Sadly, the best way to ensure this would be to write your pages using both "horseback riding" and "horse back riding" in the text -- or perhaps on some of your pages, use the single word version and on others, the two word version.

I'm using all these capital letters on purpose. Far too many people new to search engine optimization obsess with the meta keywords tag. FEW crawlers support it. For those that do, it MIGHT! MAYBE! PERHAPS! POSSIBLY! BUT WITH NO GUARANTEE! help improve the ranking of your page. It also may very well do nothing for your page at all. In fact, repeat a particular word too often in a meta keywords tag and you could actually harm your page's chances of ranking well. Because of this, I strongly suggest that those new to search engine optimization not even worry about the tag at all.

Meta Robots Tag

One other meta tag worth mentioning is the robots tag. This lets you specify that a particular page should NOT be indexed by a search engine. To keep spiders out, simply add this text between your head tags on each page you don't want indexed.

You do NOT need to use variations of the meta robots tag to help your pages get indexed. They are unnecessary. By default, a crawler will try to index all your web pages and will try to follow links from one page to another.
