A blogger who blogs for money from ads or affiliate programs needs to optimize his or her blog to bring in traffic
. Link building is still one of the pillars for SEO. Building links can be very frustrating, especially as a beginner blogger.
Many people resort to illegitimate and unethical ways to build links. However, there are plenty of legitimate and easy ways to build good links to your blog while at the same time expanding your network.
The easiest way is to follow other people's blogs and to comment. Usually you will be asked to fill in a form including your name and your website before you can leave a comment. When the comment appears on the entry or comment page, your link will also appear then.
Of course, when you comment on other people's blog, you need to leave constructive comment that is relevant to the entry. Leaving spammy and promotional comments will only lead your comments deleted by the blog owner. Some blog owners will go so far as to IP ban spammers.
Your comments can attract or repel people from taking a look at your blog. Good constructive comments will attract people to your blog and writing. It is a way to get new followers and readers to your blog. You also gain new knowledge, network, and experience.
Same principles apply when you participate in online forums. Contribute something positive to the forums you are active in instead of just littering the forum with your links and self promotions. After a while, you may gain respected position, maybe as a moderator. This position will draw other members to your blog and respect your writing.
