Since June 2009, I was active on the purchase links in Sapa . Links purchased for two different sites of the two schemes:
- by NURC purchased references only with reputable sites on this topic;
- on Ai Pi Mani bought up links from any (other than zero) pages indexed in Yandex.
There were purchased for 300 links to each of the projects. Every two weeks links indexed, checked on. If a page with a link to fall out of the index, instead purchasing another. Thus, the amount of purchased options all the time maintained at 300.
What conclusions can I do?
Since June, was not one update, so you can draw some conclusions.
Despite the fact that the TCI - is primarily a thematic index of citing, operate best links from the sites of various subjects and authority.
To my surprise NURC TCI reduced from 40 to 10 (TCI today and still not recovered). This blog TCI every time jumps from 20 to 30 and back.
From all this I conclude that Yandex is an algorithm that monitors the percentage of the links from topical sites to their total. If a reference is more thematic sites of some interest, then it becomes suspicious Yandex TCI and humiliated. I note that on the positions in the search results is not affected.
After Google nullify my pr NURC for sklikivanie money on Adsense I decided to try to "glue" of his pr pr'om with another domain, as access to a support Google has not given any results.
For this, I bought the domain TalkMarkitter with PageRank = 4. In this domain, used to be a forum with more than 500,000 pages in Google's index. I then installed a 301 redirect for "gluing".
To date, nearly a month has passed, but the bonding is not fully completed: in Google's index for about 440,000 pages from the old site. Plus pr NURC has not changed, and TalkMarkitter'a fell to 2.
What I want to check the "gluing"?
Gluing PageRank works to legitimate sites, I know that. My goal - to see if you can recover it by pr bonding with others is not zeroed domain. If not, you probably will have to "move".
1. If the budget allows - procuring thematic links interspersed with non-thematic. If capital is not large, it is best to buy links from sites of different subjects. But in any case, do not focus only on the subject! Learn from the mistakes of others, rather than on its own.
2. Does gluing PageRank for the site under the filter PR? We'll see. It is too early to draw conclusions ...
