In this video extract Matt discusses the ever present Tag Cloud that nearly all of us use.
Is it an advantage to use Tag Clouds?
Probably not he says .. check out this video and make your own opinions .. oh and ask Matt for more .. his site is Matt Cutts Gadgets, Google and SEO
As always it’s best to test your own site against competitors sites to assess either the tag cloud issue benefits your site’s rankings and search results or not. Testing this usually means doing a manual test instead of an automated SEO service or another.
There’s nothing wrong with getting your hands dirty, even if it’s cyber dirt.
