Using “click here” as anchor text is considered a bad practice because it doesn’t tell the user what the link will direct them to by itself, without users having to read the surrounding text; because “clicking” is irrelevant in many situations (assistive devices, smartphones, etc); and because it is meaningless to search engines indexing the page.
Sadly, I have to completly agree with Jeff Atwood’s assessment of the recent decline in the quality of Google search results:
People whose opinions I respect have all been echoing the same sentiment — Google, the once essential tool, is somehow losing its edge. The spammers, scrapers, and SEO’ed-to-the-hilt content farms are winning.
