The very easy way and the most cheapest way to increase your page ranking is through inbound link. Inbound links are links that basically links that are directed to your site. The best way to get inbound links is simply to create links with other webmasters that has a relevance content with your site. These are known as natural links — the type of link which is created purely to increase the usefulness of the internet (in an ideal world all links would be natural). Natural links have many advantages:
- You don't have to work to acquire them (except creating the content in the first place).
- They are free and you don't have to reciprocate the link.
- The links will be diverse, with different anchor text.
- The referring pages tend to be similarly themed (this is likely to become more important in the future).
If you are lucky you will attract enough natural links to give your site a boost. However most websites need to make an effort to acquire inbound links. You must be very careful about this! There are many ways to create links to your website — some of them are acceptable and some aren't. If you use the wrong methods, search engines may detect this and penalise you severely.
