I have a few questions about dropped domains. If a domain with google page ranking is dropped does it loose it's page rank and if so how long does that take? How often is a domain checked by google for page rank? What is the best way to increase a sites page rank? I know it's a lot of questions but any input by fellow DP members would be greatly appreciated! thanks
1. Yes, probably, depends on how many backlinks left. 2. PR of a domain will be updated in every Google PR updates which happens about once every months. 3. There are many factors influencing the PR, but seems number of quality backlinks should be the most important. You should spend more effort to have more quality backlinks linking to your domain.
