Search engines are unable to view graphics or distinguish text that might be contained within them

Image Alt Tag Descriptions

Search engines are unable to view graphics or distinguish text that might be
contained within them. For this reason, most engines will read the content of
the image ALT tags to determine the purpose of a graphic. By taking the
time to craft relevant, yet keyword rich ALT tags for the images on your web
site, you increase the keyword density of your site.


Although many search engines read and index the text contained within ALT
tags, it's important NOT to go overboard in using these tags as part of your
SEO campaign. Most engines will not give this text any more weight than the
text within the body of your site.



Invisible text is content on a web site that is coded in a manner that makes
it invisible to human visitors, but readable by search engine spiders. This is
done in order to artificially inflate the keyword density of a web site without
affecting the visual appearance of it. Hidden text is a recognized spam tactic
and nearly all of the major search engines recognize and penalize sites that
use this tactic.

This is the technique of placing text on a page in a small font size. Pages
that are predominantly heavy in tiny text may be dismissed as spam. Or, the
tiny text may not be indexed. As a general guideline, try to avoid pages
where the font size is predominantly smaller than normal. Make sure that
you're not spamming the engine by using keyword after keyword in a very
small font size. Your tiny text may be a copyright notice at the very bottom
of the page, or even your contact information. If so, that's fine
