Welcome to the Q&A Forum

Hi everyone! Using the Open Site Explorer tool I can see many of my competitors leave blog comments which (according to the tool) are providing link value to their sites. This seems like something that can easily be used in a black hat sort of way. My question is this - Is leaving comments on blogs an effective way of generating positive links to my site? Adrian

Hi there, really new to seo and loving being able to research everything on seo moz. I have a question about the ip address of my site: I use a company that sells templated real estate websites (I'm a realtor) and I'm noticing all of their websites show as having the same ip address. There are probably 100's of sites on their server targeting the same keywords as I am, would this affect my ranking at all? I'm just considering switching to a Wordpress site with a unique IP address, so I'm curious to find out how the seomoz members would answer this question. Cheers, Adrian
