Hidden Text and Links

Hidden text and links is a primary reason a site maybe seen as "untrustworthy" and is likely to suffer from a low search ranking. The reason is simple, the information you give a search engine is different to that which you are giving to your "real users". Common ways to hide text include:

    using the same colour text as background

    putting text behind an image

    placing text (using css) off the page, i.e out of view

    using a font-size zero (0)

    using image alt-text incorrectly

Further to the above being used to hide links you can also:

    make the link image 1px wide and tall

    make the link a single character

If your site is perceived as being deceptive and untrustworthy you maybe removed from a search engines index for any period of time. If you have a developer whom is external to your business you may want to take a look to see if they have falsely helped rankings (in a black hat manner such as this) by viewing your site using a text-only browser such as LYNX.

Not considered to be hidden content from users are 3rd party scripts such as: Flash, Silverlight and JavaScript. However such scripts and applications are not index-able via search engines  (although google and yahoo can index part of flash files). To ensure maximum indexing of a page you should consider cutting down the number of 3rd party scripts, using attributes supplied for alternative text and if you have a video on your site supply a text description.

Finally, if you find your site has been removed from indexes due to the above and you've fixed the problem contact the search engines in question and tell them you are sorry and ask for reinclusion into the engine.
