Lesson (7): How Search Engines Rank Pages

Every smart Search Engine Optimizer starts his or her career by looking at Web pages with the eye of a search engine spider. Once the optimizer is able to do that, the path is half way complete to full mastery.

The first thing to remember is that the search engines rank “pages”, not “sites”. What this means is that you will not achieve a high ranking for your site by attempting to optimize your main page for ten different keyword phrases. However, different pages of your site WILL appear up the list for different key phrases if you optimize each page for just one of them. If you can’t use your keyword in the domain name, no problem – use it in the URL of some page within your site, e.g. in the file name of the page. This page will rise in relevance for the given keyword. All search engines show you URLs of specific PAGES when you search – not just the root domain names like http://lilacor.com/ but the paths like http://lilacor.com/about/.

Second, understand that the search engines do not see the graphics and JavaScript dynamics your page uses to captivate visitors. You can use a graphic image of written text that says you sell beautiful Christmas gifts. But it does not tell the search engine that your website is related to Christmas Gifts – unless you use an ALT attribute where you write about it.

Here’s an example to illustrate.

What the visitor sees:

Beautiful Gifts Image

What the search engine will read in this place:

<img src=”http://lilacor.com/images/1.png” width=”250″ height=”100″ class=”image” />

As you see there’s nothing in the code which could tell the search robots that the content relates to “Christmas”, “Gifts”, or “Beautiful”. The situation will change if we rewrite the code like this:

<img src=”http://lilacor.com/images/1.png” width=”250″ height=”100″ class=”image” alt=”Beautiful Gifts Image!!!” />

As you can see we’ve added the ALT attribute with the value that corresponds to what the image tells your visitors. Initially, the “alt” attribute was meant to provide alternative text for an image that for some reason could not be shown by the visitor’s browser. Nowadays it has acquired one more function – to bring the same message to the search engines that the image itself brings to human Web surfers.

The same concerns the usage of JavaScript. Look at these two examples:

1.    Visit our page about discounted Samsung Monitors!

2.    <script language=”JavaScript” type=”text/javascript”><!–document.write(“Visit our page about ” + goods[Math.round(0.5 +(3.99999 * Math.random()))-1]); –> </script>

The first example is what visitors see, the second is the source code script that produces the output. Assume the search engine spider is intelligent enough to read the script (however, actually not all the spiders do); is there anything in the code that can tell it about the Samsung Monitor? Hardly.
