Silly question, just curious Scenario: You're ranked #1 on your keywords. Other sites on there aren't fully optimized to it. You make a few links around the web to that particular google keyword search.
Surely that's the wrong way round - all you'd be doing (in theory) is increasing the PageRank of a google results page. Anyway, as far as I can see, the individual search doesn't have any PageRank. Google home page does, the results don't.
Yeah I used to try that years ago, as far as I can tell minimal benifit. you will get only about 0.15PR per page/serp result.
You would be spreading the link juice to your competitors just as much as yourself (unless you own most of the results on the page). Not worth it IMO.
Unless he linked to a search like @:sitename.com so if he had 100 pages indexed thats 10 pages of results, with deeplinks. However you have to factor in the fact that the PR decreases by about 15% from page to page so even if you linked to it from a high PR page it would bleed off PR more for every new google page.
