As you know external  links that point to your website will help give the relevant web page more authority with the search engines. Link building simply refers to an issue in seo known as relevancy. When ranking sites in search engine results, Google tends to list the site that is the most relevant.

As you probably know, new sites are not ranked by Google. Instead, your site will sit for six months or so in the much discussed Google sandbox. Given this fact, you really don’t need to worry about Google for the same period of time when it comes to link building. Google isn’t going to rank you anyway, so picking up the pace when link building isn’t really a problem.

When linking text, you should use keyword phrases for back links to your site or inside your site. This is especially important with both internal as well as external backlinks that point to web pages on your web page.

Here are a few SEO tips from someone that has been doing it for years.

Link building is the single most important thing you can do to get your site ranked highly by the search engines. With enough quality links pointing back to your site, you can easily get your site ranked in the top 20 results for many common keywords.

First, you’ll want to identify free web directories that will allow you to submit your URL. You can start by checking out the “Directories” category on the Links page of the Easy Ways to Earn Money Online blog (see the link at the end of this post). It includes several of the best free website directories. It’s worth noting that most of the free link directories are actually link exchange networks, in the sense that they typically require a reciprocal link on your website pointing back to the directory. Why? Because they know that the more links they have pointing back to their site, the better their page ranking will be.

Once you’ve identified a list of free web directories and link exchanges, you’ll need to go to each site and review their submission guidelines. DO NOT use a directory submission service. You have no control over how these tools will handle your submission (or if they submit anything at all).

The process of link building takes time, since most reputable web directories will want to review your site before listing it. As a result, many will take anywhere from several days to several months to add your URL to their link exchanges.

In the meantime, you’re website will have little or no traffic and you’ll be largely invisible to the major search engines. A better strategy would be to get your site listed with as many website directories and link exchanges as possible–regardless of page rank. This way, you’ll get a small boost from the sites with a low page rank while waiting for the big boost from the sites with the high page ranks.

Finally, you can substantially increase the number of outbound links on your website by creating your own link directory on your site. Create a form that allows your visitors to submit their URL (or the URL of other sites they like). Just be sure to check out the sites for signs of illegal activity before including them on your site. You can even use your web directory to post all your reciprocal links in one place.

Remember, link building using free web directories and link exchanges is a lot like farming – if you don’t take the time to sow the seeds, you’ll never reap the harvest.

Here are a few more link building SEO tips. These are all free options.

- Find related websites and offer to trade space. You allow the website owner to put a link on your site. He allows you to put a link on his.

- Create a daily blog with links to your website. Provide helpful information related to the products that you sell or promote on your sit.

- Write informational articles and post them at EzineArticles, Amazine or Go Articles, three of the top article directories online. Posting is free and each of the ezines allows back-links in the body and in the article box.

The next link building SEO tips have to do with social networks. You should have enough confidence in your products or the ones that you are promoting to encourage your friends and family to buy them.

If you do not have a Facebook and a MySpace page, then you are a little behind the times. Twitter is the latest thing, but for user friendliness and beginners, Facebook, first.

The more links that you have leading to your website, the more traffic you will get. You cannot have too many links. If you also have outgoing links, then your site ranks higher in the search engines.

So, those are my link building SEO tips for the day. Hope they help you drive more traffic to your site.
