cording to research by expert SEO researcher Jerry West of
WebMarketingNow (http://www.webmarketingnow.com)
and Search Engine Academy (http://www.searchengineacademy.com),
at the present time, none of the "Big Three" search engines
(Google, Yahoo!, nor MSN), considers ALT text when determining
relevancy.
West explains, "Over the last six months, we have seen a trend on
our testing servers that shows that using ALT text for SEO purposes
has not only diminished, but adversely affects the rankings in the
SERPs. It is clear that search engines continue to catch up to "SEO
tricks" that are intended to improve search engine ranking while
damaging the visitor experience. The American Disabilities Act
(ADA) has strict guidelines as to what your site needs to contain
in order to be ADA compliant. I guarantee you, they do not look
favorably at ALT text that has been keyword stuffed.
"Have you ever witnessed a visually impaired individual use the
Web? With a device which reads aloud the contents of a Web page,
the impaired individual will be inundated with what I refer to is,
ALT Text Spam. Sometimes the reader is stuck on one graphic for
more than 40 seconds reading all of the keywords that have been
stuffed.
"According to a Google engineer, what you should do it create an
ALT tag that is relevant to the picture, so it gives the user a
good experience, including the visually impaired. The ALT text is
indexed, but it is down graded in the algorithm. The reason?
"‘We see ALT text as relevant as the Keyword Meta tag,' said the
engineer. That should say it all as Google has never used the
Keyword Meta tag due to the high spam rate.
