What are Backlinks?
Backlinks are links from other websites that point to yours. Preferably the backlinks are not reciprocal. When two website both link to each other it is not a bad thing, but also not very beneficial when it comes to SEO.
A link to your website is considered as a vote for it. These votes for your website will help you to appear higher in the search engines. A website with a lot of authority, or high pagerank (PR), has a stronger vote; a backlink from one of these websites may be worth more than hundreds of backlinks from low PR websites.
What are nofollow links?
Not all backlinks are equal. There are regular links to your website and there are also “nofollow” links. When the code rel="nofollow" is used for links, the link is no longer considered a vote for your website. Nofollow links are not completely useless, they still give a tiny benefit, or a little bit of link juice, and may help with your pagerank. From using social websites you can quickly get thousands of these nofollow backlinks, and in large numbers like this it is definitely beneficial. Nofollow or not, any link to your website is a potential for getting more traffic.
Backlinks are important not just for your main website URL, but are also very important for each page on your website. Hubs on HubPages, and lenses on Squidoo also benefit from backlinks. Many have found having a diverse amount of backlinks (links to different pages of their website) has helped them achieve great results in the search engine rankings.
Where can I get backlinks?
Backlinks can come from pages like HubPages, Squidoo, Digg, Twitter, Facebook, StumbleUpon, reddit, and much more. For any website that you have signed up to make sure you check to see if they allow you to place a link to your website in your profile. If you make YouTube videos, for example, you can place a link to your website under the description of your video. It's also important to be active on the social websites. These websites can be great sources of traffic in themselves. If there is an option to “friend” people or to “follow” them make sure you do so, because this lets people know you exist and gives them a chance to check out your websites.
Finding blogs related to the niche of your website is another way to get backlinks. Usually links in comments are nofollow, but not all of them. You can also buy backlinks online from places, such as eBay. Just be sure to check out their feedback, and that they provide you with a report once they are finish. Remember that quality content is what will keep someone at your page, if it's not good enough they will immediately bounce.
It's important to remember that backlinks are just one part of search engine optimization. Just as SEO is just one of the ways to get more traffic to your website.
