The “NO” in the 4th result you point out is the scraper telling you the backlink no longer exist at the target URL.

Remember, most of these SEO tools scrape Yahoo SiteXplorer for the actual link data, the trouble is, Yahoo is far from perfect and often out of date. So whilst the link will be scraped, that’s no indication that it still exists on the target site.

Once the link has been scraped from Yahoo, the tool will then scrape the actual page to see if the backlink still exists, the “NO” just means either there has been an error scraping the destination URL, or in most cases, that the backlink is simply no longer exists – which also accounts for the N/A in the anchor text section.

Hundreds of High PR followed backlinks with identical anchor text built in a short period of time to a new site could certainly look a little unnatural, but personally I’ve never had any problems so far. I think the most important thing is to actually mix up the anchor text a bit – but followed links definately have a far more drastic effect on serps than nofollowed anchor text links. The one thing I would discount is PR, my testing seems to have shown that so long as the link is followed, the anchor text will certainly have the desired effect regardless of PR. If you are in an especially competitive environment, then PR could play a more important role, although I’d say domain age of the site linking to you is a fairly important factor right now too, alongside relevancy.

I’m of the thinking that a good mix of all types of links, follow and nofollow in this case, appears as a more natural incoming link structure.

I've always been dubious whether the nofollow attribute does not pass any anchor text on, I've always had an incline that it does although never tested as you have.

I would definately still say that a nofollow attributed link can pass on relevancy and trust however, and that when building a healthy link profile, nofollow links should be included for more naturally built links.

Dave stated in his post that the nofollow attribute would not pass link text. I simply found, through a little testing, that to be an incorrect conclusion.

Would you agree that if the anchor text wasn't passed the results should be n/a as shown in the 4th result down in my screen shot?

For the record I don't fret whether a link is a nofollow. IMHO there is to much hoopla around the whole thing and not enough hard evidence one way or the other to discount the links totally.

I could be wrong though, there's a possibility I'm not understanding your explanation here, so if you could further explain why the above is proof that anchopr text is giving weight from a nofollow link, then please do!!
