USE OF FRAMES AND  SPECIALTY/HIGH-TECH ITEMS   Frames-Based Website Issues At least half of the major SEs do not spider frames-based sites. Because framed sites serve up two or more pages at once they are difficult for the SEs to handle. SE spiders don't know how to follow the frame links within a frameset document, so they ignore the information within the <FRAMESET> tags. When designing your website, whether or not to use frames is an important consideration with regards to getting well listed with the SEs. If you're really set on using frames as part of your website design, consider making a second "non frames" version of your site. This is the version which you will submit to the search engines. Other considerations if you have a frames website: Make sure your index page includes a <NOFRAMES> section. Within the <NOFRAMES> section, include a link to your non-frames site. The search engine spiders may follow this link, and index your non-frames site. (However if you do have a non-frames site, then you shouldn't be submitting your frames site to the SEs in the first place) Make sure that each and every frames page contains a title tag. Visitors who somehow enter your site through one of your frames pages need a way to get to your index page. So make sure all pages contain a link for visitors to return to your index page (which contains the main frameset). High-Tech and Specialty Items Issues You should keep high tech and specialty items lower in your HTML documents. Java, Flash and streaming audio or video can confuse the spiders which can result in your page not getting the listing it deserves. Most SEs will not spider dynamically generated pages. URLs which contain "?" and "%" characters, or any other specialty characters or extended characters, likely will not be indexed. The SEs are worried about hat they call "robot traps" where there may be no end to the number of links that a script or program generates. Therefore they will not attempt to spider a program which dynamically generates a webpage.
