SEO

Building links to your site is one of those things that is far from glamorous. It can be downright mind numbing at times. But it is one of the primary reasons the sites ranked above you are there.

A strong backlink profile is crucial for any business trying to get customers through the search engines. Unless you have the budget to spend a ton of money on Pay Per Click.

Some great methods you may want to think about are:

Guest posting.
Building Lenses or Hubs.
Posting to a few Article Directories.

Guest Posting
If you’re a writer (ie you enjoy writing), the best method for building quality links to your site is through guest posting.

To do this, you approach a website owner and offer them an article written by you that they can publish on their site. At some point in the article there will be a link back to your site, possibly in the blurb.

The key to this is to follow that site for a while and see what they talk about. Make sure what you offer the owner is your highest quality work tailored specifically to their site and audience.

This works so well because you’re getting usually a pretty solid link from a site with a fair bit of authority and at the same time exposing your work to a wider audience. Done right, you’ll get far more benefit than merely the link.
Lenses or Hubs
Squidoo pages are called Lenses, Hubpages pages are called Hubs (bit of a tongue twister there).

The general idea is the same for both. You build an authority base on those sites by publishing great, useful content. The more you create and engage, the better return you’ll get. Think of them as social media for article marketing.
Article Directories
Like with the previous, only work with a few of the major article directories, like Ezine Articles, Buzzle, iSnare

This is something that I can’t believe I haven’t heard other people talk about yet, but it’s so simple and easy to implement!

When you’re surfing the net, catching up on the news, reading your favourite blogs, etc – if they have a comment section, take an extra 2 minutes and comment on what you just read, linking back to your site.

So many people finish reading the blog post and just move on that it baffles me!

Leaving a comment does three things:

You get a link back to your site.
You build your network.
You make the writer feel more motivated to write.

It doesn’t get better than that.
You Get A Link Back To Your Site
If you’re like most people, you are already spending time and money building links to your site. Commenting on blogs in this way is an excellent way to give a bit of a boost with natural looking links. Of course the reason they look natural is because they are natural.

Sometimes we get so lost in checking for a high PageRank and dofollow that we lose sight of normality. Don’t worry if the blog post is a PageRank zero or whether the link to your site would be nofollowed. Don’t worry about putting keywords in the Name
