1. Link Building
This is the first part of common SEO tactics and it can be broken down into several techniques or methods. But the basic principle here is that you spread links going to your website throughout the internet. This is done because one of the factors that affect search engine rankings is the number of links leading to the site. Basically, each link is a “vote”. The idea behind this from a search engine standpoint is that if a lot of websites link to a particular website, then that means the receiver has good content and is deserving of a higher spot in the rankings. Link Building is done in order to replicate this effect.

2. Directory Submission
This is the first and probably the most common link building method there is. Almost any website today uses this method and all SEO specialists are at least familiar with this method. It is the fastest and easiest way to gain links from all over the internet. So how does this go?

First off, there are websites on the internet designed to provide people a service similar to that of the Yellow Pages. The main difference is that instead of providing the address and phone number of a particular business, it provides the URL of a particular website. These sites are called Directories and they are huge compilations of various sites all over the internet.

What’s great about Directories is that they also categorize the sites listed in them. Although categorization can differ from one Directory to another, it’s still very helpful that they are categorized. And, another great thing here is that you can use them to gain links for your site.
