Comment blog can drop PR ?

I heard that many comments in the blog cam make down pagerank. Is it correct? Than, how to reject incoming comments in wordpress blog without selecting ?

 

Just disallow all comment if you don't want to moderate

 

yes it is true .....
post if we are rubbish ....

 

Thnx guys for your respons and input.

 

No, it's not correct.
How on earth could Google possibly justify penalising bloggers for the actions of their commentators?

 

I use askimet to filter out comment spam. Other than that, I don't get a lot of useful comments so I don't sweat this issue. However, I don't buy the whole thing about it lowering page rank. I've seen the opposite...pages with a lot of traffic and interaction usually do well. Unless of course the comments being approved are trash.

 

Make all link in no-follow. It can prevent your blog form spamming or other non-thematic link which is bad for page rank.

 

akismet is the best option

 

Google would never downgrade your SERP/PR if you have more no of comments....But spam comments may degrade page's quality....Nofollow is the best option to avoid spam
