We hope there is no confusion on your part about the need for off-page SEO which means backlinking. You should proceed with a healthy amount of caution with backlinking if you do not have a solid grounding in it. If you want to do this for yourself, then take your time while you learn and then take action. There are a ton of methods to gain backlinks, so just be sure about what you are doing.
There is a great deal within the body of information surrounding BACKLINKS. It is hard to beat a place like a forum because that is where you can go and make friends and discuss your topics, etc.
While you are engaging in all that good stuff, you can simultaneously create a few excellent backlinks in a number of ways. Most of the forums these days allow you to have your site’s link in the signature. Since forums are popular and frequently visited, the search engines like them. But just be sure you read the forum rules about signatures before joining.
If you have never considered press releases for backlinks, then you need to change that and look into it. While not every press release will take hold, some of them will which will only help you. Eventually it is good to maybe buy a PR package, and that will guarantee your site a ton of great backlinks. In addition to backlinks, you will get more traffic once you have some built up.
You can get your content and comments on blogs in other ways, and being a guest and blogging or posting is a viable method. Of course you have to be able to produce good posts, and so you should pursue it if that is not an issue. What you usually see is something on a blog indicating they accept guest bloggers. It takes time and effort to apply this method, but eventually it’s worth it. You need to be reasonable because a high PR blog will likely not accept a PR0 blog owner.
Sure, a lot of this takes time, but that is just what must be done unless you hire freelancers. It can be boring, but it is really easy work and you can do it fast.
Be sure to get it all right so you maximize your efforts and get a good ROI. While you are building your backlinks, do not ignore the on-page SEO factors because they will help.
