Hi, My server has a problem 2 weeks ago, and i had no page there for 2 weeks. my pagerank was 3 and now is N/A. now my site live again. what should i do to get PR back? Thank you.
Too bad for you, so sorry. Check too if your site still have indexed pages and cached by Google. If you have results, just continue your usually updates and link building and wait for the next PR update. But if you got no results, its more likely your site is penalized.
For a meantime optimize your website as much as you can by increasing the number of your backlinks for the next PR update. It will take 3 to 4 months for the next PR update so you still have a lot of time to build links. Good luck!
Next update your PR will definitely get back, so meanwhile your can even get it higher by building good back links.
