Let’s say that on your homepage, you have two links to your blog. The first link is in the navigation, the second link is in the body. That second link’s anchor text is NOT going to help the blog page rank for the anchor text used, because Google doesn’t appear to count the anchor text from multiple links to a target from a single URL.

a) This was already proven last October:http://sphinn.com/story/8887b) He’s giving bad info in the post and comments. Currently you cannot sculpt PageRank from one link to another link of the same target using nofollow. Check any of the phrases used in the anchor texts of the links in the test in this page, adding nofollow to the first one didn’t do anything:Single Source Page Link Test Using Multiple Links With Varying Anchor Text - Part Two

Michael, perhaps it’s your b) link that we should all be sphinning.  It makes sense, which may or may not mean that Google actually always does it.

bwelford, thanks. I never did write a follow up post explaining what the results meant with that test, perhaps I should.

I’d certainly be interested in hearing it :) - it would be an interesting topic for discussion

The idea of using nofollow to "shift" which link’s anchor text counts is nice, but I don’t think it actually works. Relying on that kind of undocumented and speculative behavior, even if it worked once, can cause some real headaches down the road.If you want to scuplt PageRank with nofollow, all links from page A to page B should be nofollowed. You either cut the link between the two pages or you don’t.@Michael, thanks, I thought I’d seen something published a couple years back, maybe longer, but certainly that Sphinn showed up well before this one.

"The order of operations is dedupe first (remove all duplicate links), and then apply the nofollows."Interesting.

Whatever SEO impact the current behavior has is interesting in the short term, but it’s important to bear in mind that whatever they’re doing is designed for efficiency, and subject to change for any reason. We have older tests that give a different result, so it’s likely that this behavior has changed at least once.

"it’s important to bear in mind that whatever they’re doing is designed for efficiency, and subject to change for any reason."Agreed Dan. I’m not sure if this behavior will change though. Say you got a several links on a page pointing to the same target URL. First (top of source) is an image link with anchor text "home", second is a contextual link in an article with anchor text "las vegas", and third, a footer link with anchor text "las vegas real estate." Two ways to handle this: all anchor texts apply OR only one applies (according to this article, the current set up). Now, ideally Google would choose the "best" anchor text ("las vegas real estate") out of the three, but that would require some pretty intricate logic - coding that into Googlebot would probably really slow it down.

It wouldn’t actually slow down Googlebot.

"I’m fairly confident that actual anchor text analysis is not done by the bot, but rather at the ranking algo end."Yeah, that’s also the way I look at it mvandemar. My point was if Google wanted to handle things differently, it may need a more complicated Googlebot. I guess Google can record links on a page during crawl, then handle dupes post-crawl, but that would still require more number crunching than the current set up, which is more of a *hack* than anything else. It’s straight-forward to code a bot to choose the first link, but if I had to code a scraper to choose the "best" link, I’m not sure how I’d go about coding that.

Right. Assuming you need to de-dupe the links because you don’t want parallel edges on your graph, then you have a couple choices. You can mash all the duplicate links together into one big link, or you can pick one.If I were writing the algorithm, mashing them together would make more sense, because you aren’t losing the anchor text when bloggers say "Pat Johnson(link) wrote an amazingly stupid thing about widget margins(link)." If you just take the first link, you lose the topic of the target URL.All these tests are showing that they pick one link to use, and apparently it’s the first one.  Any notion of efficiency would go out the window if you had to run some elaborate routine on every page to pick the "best" link, so that first-link-wins behavior does make sense.You see all the time where people nofollow the "Home" link that appears at the top of every page, and add a footer link to the home page with their keywords stuffed in. The problem is that you may end up not getting either link followed - you’re relying on Google to remove the first link and still follow the second link. Highly speculative.

"I guess Google can record links on a page during crawl, then handle dupes post-crawl, but that would still require more number crunching than the current set up, which is more of a *hack* than anything else."Actually, I’m was thinking all they would have to do is switch the order of operations around... first remove the nofollows, then remove the dupes. That way there would be no conflict and it shouldn’t affect performance at all.

I wonder whether 301ing fake landing pages to homepage would allow multiple links with different anchor text pointing to the same URL ? Or some non-existing parameteres ? That would be an additional thing for the algo to calculate and easy to circumvent, but who knows?
