Welcome to the Q&A Forum

That's a good idea.  It's strange, though, that it would have crawled almost all the other links on the site, but not this one, which is the one linked to most conspicuously from the home page.

I have been doing this a long time now and have never come across anyone who endorses this as a technique. To me if it smells even slightly of desperation or 'grey hat' then I steer well clear. You can  rest assured that Google will get what the page and site are about without having all of these multiple links to the same pages being thrown at them - in the same way they say not to keyword stuff because they don't need to keep being told Regards, Andy

Hmm... all depends on your definition of "conversion". On several sites, a "conversion" is farming visitors off as quickly as possible to another site/partner; and sometimes having an ugly site, with poor grammar and a single link leads to a user leaving the site through the link out of sheer desperation... and there's your conversion. If you're talking directly about selling as a conversion though, then that's a completely different matter. Many users won't part with their money on a site where the "service quality" is implied to be inferior... as it is when communication (a part of service) breaks down.

Very insightful anserws, thanks!
