Top 10 reasons why PageRank goes down!

1. Site goes down frequently. (Googlebot/webcrawler/spider couldn’t crawl your site)

2. Including new outbound links (when inbound is less)

3. Folder restructuring (this will hurt initially) and if the new structure has multiple sub folders to  post then the chances of pagerank will be less.

4. Keyword stuffing (this will end-up in site getting banned)

5. Multiple languages getting displayed in same post (I have to check on this though)

6. Nested table structure.

7. Duplicate content from other sites or duplicate domains with same content.

8. Key sites that is linking to your site earlier, removes your url.

9. Black-hat techniques.

10. Increased content which is way too huge to load on a particular page.
