Our index size is varying from update to update as we tune quality vs coverage

And this creates some issues around historical tracking. Believe me, we are working on the issue, stay tuned for more information around this scenario. More interesting is an Index Quality Study we finished just before this update. From that study two things are immediately interesting to me. Linkscape Index Coverage vs Yahoo! Site Explorer First, we estimate that between 60 and 70% of what Y!SE might give you (including no follows, duplicate links) are in our index today (the small one, remember?).


Moreover, we estimate that nearly 50% of what Y!SE lebanon mobile phone numbers database will give you, we could too, but we filter out as duplicates, nofollows, or otherwise less important than other data we've got in our top 3000 links. Next we've gotten a lot of feedback about how mozRank matches intuitive understanding. Sure it's a 10 point scale, similar to Google Toolbar PageRank, but often people are finding it's off from what they're expecting. This is because of the data we've been optimizing our index for: Linkscape Index Focus on high PageRank pages In the past we've been concentrating on a more or less random sample of pages users might care about (the red bars).


As it turns out, you guys care a lot more about important pages and want mozRank to be focused at describing the authority of these pages (the blue bars). So we've dramatically shifted the focus of mozRank toward these pages. Hopefully you should get a better experience out of mozRank and mozTrust for these high authority pages and sites. We have more data for partners and power users. PM me if you're interested. Finally, here's the new competitive link tool.
