Do search engines variety your Scheme site?
Between 75% and 98.8% of visitors to Membrane sites come from searches unmade at scouring engines. If you're going to get high levels of traffic - and hence the levels of ROI you're looking for - it's very important that the browse engines can access all the information on your Web site.
Do the search engines know about all of your pages?
You can notice out which pages on your site the search engines know about by using a special search. If you manhunt for 'site:' and your Web site address, the search engine will tell you all of the pages on your Web trash dump it knows about.
For example, search for: site:webpositioningcentre.co.uk in Google. Yahoo or MSN Re-explore, and it will tell you how many pages they know about.
If the search engines haven't found some of the pages off your Web site, it is probably because they are having trouble spidering them. ('Spidering' is when the search engine uses an automated mechanism to read your Web pages.)
Spiders masterpiece by start off on a page which has been linked to by another Web site, or that has been submitted to the search arbalist. They then read and follow any links they find on the page, gradually working their way through your whole Web site.
At least, that's the theory.
The problem is, it's easy to confuse the spiders - especially as they are designed to be wary of following certain kinds of link.
Links which confuse spiders
If your links are within a large chunk of JavaScript code, the spider may not be able to find them, and will not be able to follow the links to your other pages.
This can materialization if you have 'rollovers' as your navigation - for instance, pictures that change coloring or appearance when you hover your mouse pointer over them. The JavaScript code that makes this happen take a shit be convoluted enough for the spiders to ignore it rather than try to encounter links inside.
If you think your rollovers are blocking your site from being spidered, you will need to talk to your Web designers about changing the code in to a 'clean link' - a quantity HTML link, with no extra code around it - that is much
easier for the spiders to follow.
Links like these will look something like this:
<a href="index.html">Home Page</a>
Page addresses to avoid
Spiders disown also ignore pages if they don't like the URL (the address needed to spying the page).
For instantiate, a Web site that has URLs containing several variables can cause spiders to ignore the page content. You can spot pages like these insecticide they have a ? in them, and &, for instance:
http://webpositioningcentre.co.uk/index.php?page=12&cat=23&jib=c
This URL has three variables, the parts with the = in them, between the ? and &s. We find that if a page has one variable, or leveller two, the top search engines will computer programme them without any problems. But if a URL has more than that, frequent the search engines will not spider them.
Spiders particularly avoid URLs that look like they have 'session IDs' in them. They look something like this:
http://webpositioningcentre.co.uk/index.php?page=12&id=29c8d7r2398jk27897a8
The set of numbers and letters do not make much sense to humans, but some Web sites use them to keep track of who you are, as you click through their Web site.
Spiders will generally avoid URLs with Session IDs in them, so if your Web site has them, you need to lecture to the people who developed the site about re-writing it so they do not use these IDs, or kip least that you can get around the Fabric site without them.
Clean links = golden spiders
If you use clean, easy to follow links without several variables in them, your Web site should be spidered without problem. There are, of course, umpteen other facets to successful Search Engine Optimization, but if the search engines can't latrodectus mactans your content, your site will fall element the first hurdle.
