Hi everyone and happy holidays to you! The following relates to "dofollow" blogs, of course. If I'm building backlinks (through blog commenting, in this case), what is the largest number of links that can be on a PR2, PR3, or PR4 page before its "link juice" becomes diluted? Also, I read that if you divide the page's PR by the number of outgoing links, you get the link juice value. Is this correct?
There is no real limit. Google used to suggest that you keep it to 100 outbound links per page and your page footprint to 100K but those were limitations in their crawling process, index size, etc. Back in the day, they would frequently only index the first 100k of a page and only follow about the first 100 outbound links on a page. But those limitation don't really exist any more. It is still a VERY good guideline to limit your outbound links to no more than about 100 per page. However, Googel will follow all of the links on pages with several hundred links these days... and index all content from pages with many times more content than 100k. If you are talking about Google page rank... then YES. You are correct... If a page on your site has X page rank points then each followed outbound link is passed approximately X/(TotalNumberOfOutboundLinks). I say approximately because there is something called a damping or decay factor that causes a small amount of PR to be lost and not passed out (approximately 15%). "Link juice" is a more general term than Page Rank. Page Rank is specific to Google... their "version" of link juice. Each major engine has something similar to Page Rank, but they each calculate it differently. "Link juice" is just a termed used to talk about them all collectively.
I once read an aritcle saying having 100 outbound links on a page would be considered as a link farm, which will be punished by Google.
Check the google suggestions and be careful not to get into trouble by violating any rules. Sometimes they are really confusion.
I suggest not more then 40 in a page better you create another link page. even more then 40 link it's look very cheep
It truly depends. There's no "fixed" number. Google and the other search engines are using many different mechanisms to determine the ranking for a page and/or website. Universal Search and Universal Search indicators are playing a role. Plus, there are impacts from the social networks that determine things such as social influence and will also affect ranking.
I think you can have a limit of 10 OBL............................to get PR easily.............................
Why do you need 100 dofollow outbound links ? I`m browsing the net quite often but I haven`t seen so many outbound links on a page.
This is a great post! Canonical provided great info here. I had no idea about the suggested limit of 100. Thanks for posting.
Depends on the page. If you are creating a vendors page, a list of area restaurants or some other kind of valid and useful list, you can go over 100. Do what is right for your visitors.
This is not true. 100 was just a guideline back in the day because Google used to ignore all links after about the 100th link... You can have 500 or 1000 outbound links on your page and not get penalized. There is no limit really... 100 or less is still a good rule of thumb... But only because any more than that and you are passing each page less the 1% of the PR of the page where the links live. The fewer links on the page, the more juice/page rank you pass to each of the links. The definition of a link farm is basically when someone owns lots of sites that all interlink to one another for the sole purpose of passing each other PR and manipulating search results. By its very definition, a page can never be considered a link farm simply because it has 100+ links on it. If a site links to 100 different sites which all link to each other THEN it might be considered a link farm... But that might be true if even 30 or 50 sites all link to one another. It has nothing to do with the number of outbound links... Are you kidding? MOST commercial sites have more than 100 outbound links per page... Outbound links include links to other pages on the same site as well as links to pages on external sites. Hell, a lot of commercial sites will have 50, 75, 100 outbound links in their footers alone. Check out some of these: http://newyorkpost.com/ - 233 outbound links total http://online.wsj.com/home-page - 291 outbound links total http://www.bestbuy.com/ - 228 outbound links total http://www.walmart.com/ - 327 outbound links total The list goes on. And NO... these are not link farms. They will never be penalized for having too many outbound links. The ONLY way outbound links will get you penalized is if: 1) You are selling followed links and Google catches you 2) You are participating in some type of linking scheme with followed links whose sole purpose is to manipulate the SERPs and Google catches you or 3) You link to a bad neighborhood site (another site that is violating Google's webmaster guidelines) with a followed link and Google catches them and penalizes you for promoting a site that violates their guidelines. These things can all get you penalized even if you only have ONE outbound link on the page and all of the above penalties can be avoided by adding rel="nofollow" to the potentially offending link. There is absolutely no penalty for having too many outbound links on a page. The only ill effect of having lots of links is that you dilute or reduce the amount of link juice/page rank passed to each page being linked to since PR, like most link juice formulas, is inversely proportional to the number of outbound links.
You simply cannot divide the page rank of the page by the number of outgoing links to obtain the 'link juice' factor. The algorithm is supposed to be more complicated than that. That said, I would say as Canonical has said here, I also recall having read somewhere up to a hundred outgoing links (not an exact figure) on the same page is OK. More than that, it could be a link farm. (penalty)
