So…”I think this is the best weight loss supplement!”

Presto. You appear under the keyphrase. Although it’s harder when the searcher pluralizes it. After all, there can only be ONE ‘best’ anything, so it’s harder (but not impossible) to write something that will catch the plural phrase.

Convincing the customer that Your Merchant’s Thing IS the best is something you should be doing anyway (after all, you ARE trying to sell it!), so other than making sure to blatantly say Best somewhere in the pitch, pitching to a “best” searcher is pretty much normal sales other than that bit of specific SEO.

As for comparisons or reviews…NAH, not unless I’m specifically trying to nuke some bad merchant (by making them the sucky alternative, muaa haa haa!). But other than those rare instances, if I say a product is THE BEST, that is IT. There is only ONE of anything that can be “best.” All others are also-rans, and therefore do not get on a page talking about the “best (item).”

Oh. And if I’m promoting it, it’s the best. That may mean best commission, or best converting, but it’s the best. If I’m SEOing for “best (item)” I usually don’t say what’s best about it. Just that it IS. *evil grin*
