Do Follow and No Follow Attributes?

[bronxpad]

I have a blog on Trulia and Active Rain which are real estate websites. I see that they both are Do Follow.

My question is how much link juice do these sites pass a long to my site when I write a blog post on these sites and create a link to my main site?

I've heard somewhere that even though a link has a Do Follow attribute it passes little link juice in certain cases like a no follow attribute.

Also, if a link is a No Follow link, does it still pass along some link juice or is it completely juiceless.

Is there a way to see which sites pass the most link juice to my site?

Thanks all.

You can look at the domain and page authority of individual pages for some idea. Because of some of the delays in how SEOmoz updates its index, you might not get as an accurate picture for newer posts.

Links near the top of the page tend to hold more weight than ones in sidebars, footers, and traditional author bios at the end of posts. Also search engines will only follow the first link to a page that it finds. For instance, if you have three links to example.com/homes, each with different (or the same) anchor texts, the search engine will only follow the first one that has a Do Follow attribute. Though you can have multiple links to different pages on the site - if the first link goes to example.com/home and the second goes to example.com/home2 then the search engine will follow both.

Further, the more posts you have on one site with links pointing to your website, the less power each individual link has. It's not going to hurt you, but the individual gains each link brings will be smaller and smaller.

So the short answer is, no there's no real way to see which sites pass "the most" link juice to your site. You can get an idea for which ones might be helping more, but it's only going to be an estimate.

I'm of the opinion that No Follow links help show that you have a natural link portfolio since having none implies that you could be spamming, but by themselves they won't do anything to influence your rankings.

There's nothing wrong per se with a 'do follow' link. It's just sort of a redundancy. You can argue that 'Do Follow' links could pass little or no link juice if a blog for example has enabled 'do follow' on comments on the blog. In this case you're kind of inviting spam and as a result, little or no link juice may be passed.

Well put , also keep in mind that to many no follow links are also not a good link profile Variation
