- Well, I believe the profiles (and thus posts/comments) are included in Sitemap files - so crawling based on URL discovery is unlikely an issue.
But weighting/valueing ... maybe different.
Alternatively - as this is a G domain, G could technically guineapig the whole thing.
What if G have ditched/devalued PR here, and bases more of it on other values/signals?Sep 10, 2012
- Agree but, think it's unlikely they'll ditch PR. Why would it display then for pages currently?Sep 10, 2012
- There is a difference between there being PR, and them using it.
As for the ditching... I don't think they will ditch PR.
If only there was a subset of data that they could play and tinker with to see how far they could go with lessening the PR influence......................Sep 10, 2012
- yet appears to utilise JS to render the relevant part.
- When you find a link with a nofollow, it doesn't mean that its purpose is to prevent the target URL to get PageRank. It means only that the search engine should ignore it. Ignoring links has profound implications in crawling, bandwidth optimization, speed of indexing, web graph complexity and many other things that you must take under consideration when you are a search engine that has to manage a property with hundred of millions (or even billions) of URLs.
Since PageRank siloing is impossible to achieve using only nofollow relations, the reasons why nofollow relations have been used are probably unrelated to the flow of PageRank.
Also, I would like to put emphasis to the following statement: "PageRank should be on display at the Museum of Ancient Algorithms.". :-D It is still useful for some needs and for academic discussions, but I think that we should all face its inadequacy for modern and more complex needs.Sep 10, 2012
- We still don't know all the parts in PR ... if we did, it may be more useful.
Maybe - if G are still unwilling to ditch the damned thing, they should go a step further?
1) Introduce the other metrics as visibles
2) Include them in the SERPs
That way - you can look and not only gauge a site because of it's position, it's Title and it's Description ... but see Googles Trust score in that site.Sep 11, 2012
