I thought I would share a quick and simple link building technique for you. most of you probably do this but for the sake of the beginners and those that don't know, here is a free and easy way to get as many links as you want.
Lets take as an example you are targeting the keyword: Local Search Engine optimization
I am assuming you have a website that is properly optimized. So you have the keyword in:
2. META Description
3. META Keywords
4. Title Tag
5. H1, H2, H3 tags
6. Within your body of content the keyword is bolded and you link to another part of your website using your keyword
7. Any images has the keyword in the Image Alt tags
Now you need to build high quality in context links. So go to Google and either use one of the following search queries:
local search engine optimization "this site uses keywordluv"
local search engine optimization "this site uses commentluv"
So you are using : KEYWORD "this site uses keywordluv" / "this site uses commentluv"
I used local search engine optimization "this site uses keywordluv" and I get 13,800 odd results where I can post a comment and receive a link back to my site. Now to further refine this I use Firefox and have installed SEOQuake and NoFollow Plugin. I use both to test if the links are NoFollow or DoFollow and I use SEOQuake to ascertain PageRank. For example I found the following url:
Maximizing the Search Engine Optimization (SEO) Of Wordpress | TechSling Weblog
This is a PR 3 link and has an Alexa rank of less than 100,000. Which means it will be crawled often as it has a decent traffic level so Google and co will find your link pretty quickly. So you can quickly find yourself a heap of really decent backlinks to your site.
NOW THE MOST IMPORTANT PART.
Post a valuable comment. It may take a little longer to actually read what is on the page but it is important to make a genuine human post as this will ensure your post is published and it is a way of saying thank you to the site owner for allowing you to get a free link from their site.
So hope this helps and have fun looking for links.
