This post, I play with my mathematics experience on logarithms. I win many math contest before and I badly needing it now . I assume that PR toolbar is a logarithmic value as a function of the number of links of an unknown base “X”:

PR tool bar = log (Backlinks) to the base X

where “Backlinks” is the total amount of backlinks from other domains pointing to the entire site.
“Base x” is the base of the logarithm not being solved so far. It is used to convert the actual back link data to a friendly Google Page rank measurement we seen in their toolbar, which will update every 3 months. (more…)

We have tested that the use of keywords in the internal link anchor text is highly effective in rankings and a particular element that separates top ranking sites to the bottom ones. Basically how we set up this experiment is very simple.

Methodology:
1. We compare two pages that ranks in Google for a particular key phrase. One page ranks in Position 1 and the other page ranks Position 100.
2. We take a random sample of around 5 competitive keywords.
3. We take a random sample of 6 pages within the domain. Then we examined the anchor text used to point to the ranking page of that domain for the tested key phrase.
4. We take the % ( number of pages containing the targeted keywords in the internal links pointing to the ranking page/ 6)
5. We average all the samples and compare the results. (more…)
