Posting on blog comments with anchor text on high ranked pages effective?

[symbolphoto]

So i've identified some blogs which have a fairly high ranking and lots of traffic. They also allow anchor text in the name field.

Does it make sense for me to comment on these blogs, or does google treat these with less authority that true page links?

Any advice is greatly appreciated!

TIA

Hi there,

Commenting on posts can be a good way of building your name in a particularly community, and even encouraging click-through traffic if the topic and the target website is relevant and of use to readers, but as an SEO technique it's really not worth your time.

For a start, the majority of blog comments are marked with the 'nofollow' attribute, meaning they pass no link value to your site, and even if you do find a blog that allows dofollow comments, it will be packed with links (making any link value passed minimal) and will have almost always been spammed, meaning there will be links to dodgy link neighbourhoods and irrelevant sites, meaning you don't really want a link from that page anyway.

By all means contribute to the community with comments that add something to the discussion or show your appreciation for a particularly well written or informative post, but your link-building efforts are far better placed in other areas.

Here's a couple of excellent posts on link-building that might help get you started:
