Hello, If i blog comment and i am targeting two keywords for my site. Can i comment twice and still benefit from the SEO? Does good only take consideration of one keyword and link from one blog comment or can i do multiple ones? Is that ok? Thanks
Not really OK, most blog owners will know what you're doing and either mark both of your comments as spam or just delete them without even a second glance. It's best to naturally post one comment that's actually relative to the blog post, and also throw your site's link up with the comment.
i should have stated that disregarding what the owners do, im just asking if its ok and will i receive credit for both.
Try to use different IPs for both comments, also make sure both comments are to the point and related to the blog post, then it looks like two legitimate comments to the blog owner so there is high chance you will get approved.
If you're using the same URL in the anchor text then don't do it because it's pointless. Google will ignore the second link so you'll lose the benefit of the second link. I wrote about this in more detail here.
