What is the optimal link profile?

[inhouseseo]

I am doing a variety of SEO link building techniques. I am doing:

• guest blog posts

• article submissions

• directories

• bookmarks

• web2.0 properties

• link acquisition

I don't expect much from the article submissions, web 2.0, and directories, so I am using these methods for the long tail and less competitive keywords. Is this a good idea?

When we talk about a link profile, is it per page or for the whole site? Does it matter if you have a more diverse link profile for a single page or does it have to be diverse for the whole site?

Appreciate any informed comments!

A good idea is to get the link profiles of all your competitors on page 1.  Then break all their links down by type, you will then get a good idea of what it takes to rank in that niche.  If you aren't hot on excel, you could try cognitiveseo - they give this type of link profile breakdown... very useful

Try to focus more on those competitors who don't have an exact match domain, it's much harder to rank when your URL does not contain at least a partial match. Google still puts a lot of weight on exact match domains. 
I would focus more on creating valuable content and post them on your site or use websites like Reddit, Digg or StumbleUpon to get the word out. Put a snippet on those sites and the rest of the article on yours. In addition, if you can share it with minded-like people, such as through Facebook, I'm sure that will improve the results.

Try googling with industry-relevant keywords and advanced search operators to find sites that Google itself currently sees as authoritative, which are also publishing guest articles, then try submitting your articles to them if your website doesn't attract to many people.
