“I use the Google Toolbar to monitor PageRank. I read on the Internet that it gives old and quite unreliable data. Can I have reliable realtime PageRank information about the sites I administer? And how can I identify causes of a PageRank drop?” silviot, Torino, Italy
The information you get from the Google toolbar is updated 3 or 4 times a year. We do not want webmasters to get obsessed with PageRank and not pay attention to titles, accessibility and good content.
What can cause a drop in PageRank? If one authority site stops linking to you that could cause a drop in PageRank.
- Canonicalisation issues can have an adverse effect. This can occur if a webpage can be accesses as www.thispage.com and thispage.com
- Another reason for dropping PageRank is if you have been selling links – this violates Google code of conduct. (Similarly links from sites that sell links may be found out and this can devalue incoming links.
