Javascript
Javascript is not evil in and of itself, despite what you may hear from some so
called SEO experts. You can create some great features for your users using javascript.
You can also make your own life easier by using some of the powerful features
that the language has to offer. Unfortunately, the Search Engine Crawlers will ignore your cool
javascript completely. The trick here is to leave the crawlers a method of successfully navigating
and viewing your site without the use of javascript.
Crawlers and Javascript
They'll ignore it....completely. What crawlers do is follow HTML links and analyze what they find
at the other end. They don't understand javascript, so don't employ it where you want them to be able
to follow. So it's perfectly ok to employ a cool javascript menu system as long as you also allow the
crawlers to do their job. A site map (see the SEOKnowHow SiteMap) might come in handy for
this purpose.
You can also employ plain HTML links within the content of your pages (like the link to the sitemap above)
to allow the crawlwers to traverse your site.
