You first need to tell us how much you know about SEO. Because it is not so small topic to cover it in one post.
If you know about search engine optimization techniques or Search Engine Optimization SEO will be strongly associated with increasing Link Popularity
First learn about what SEO really is. Read as much content as possible. Know what on-page and off-page SEO means. Then try to focus on on-page SEO and then move onto off-page SEO which comes handy and is very important but for best results try to improve your on-page SEO. On-page= Related to content on your site. Do proper keyword research, write quality content etc. Off-page= Do article submissions, blog directory submissions, link building and these will be good to give you a start.

Read the old threads and search for more in Google. If you getting any difficulty then just ask about that specifying the problem. Ever remember that- much you read, more you can learn.
