There are quite a few ways to monetize a blog. One way is by being an affiliate advertiser. Another good way to monetize a blog is to integrate ads. However, before you implement them, first you need to let advertisers to know that you are willing to advertise their products on your blog. Here is how you can do it:
1. Have a banner on your blog saying Your ad here or something similar. This way you communicate to your visitors that you are interested.
2. Offer some kind of bonuses for your advertisers. It can be like one week for free bonus, or any other that comes to your mind.
3. Consider placing only the ads that are relevant to the topic of your blog. Otherwise your visitors will be confused, and advertisers will make less money, which might cause the advertiser to stop doing business with you.
4. Keep your blog on topic. If you do not, potential advertisers might be too confused, and as a result will not consider advertising on your blog.
5. Display your website stats. If your blog has stats that are satisfactory to your expectations, show them to the public. Remember that you do not need to have very big traffic to make some money from ads. Display such numbers like Alexa rank, or geographical statistics pertaining to your visitors.
6. Have a place on your blog where you store information about yourself. Explain there briefly who you, are and why you are blogging about this particular subject.
7. Show your future advertisers where their ads could possibly appear. You can name this place ads or in some other way.
8. Keep your blog on a professional level. Write quality posts relevant to your main topic. This will convince your advertisers that your blog is professional enough to advertise on it.
