There are various actions which you can take to increase your Internet income from Pay Per Click program.
The most common and free methods that many Internet marketers do are article submissions, building links, blog commenting, social bookmarking and link exchanged. All these methods are aimed at bring niche visitors to your site or blog. The higher the volume of visitor traffic, the higher is the chances of making more money.
Among all these methods, I particularly like blog commenting. In order to maximize the advantage of blog commenting, you can do make a good plan and pay very special attention to avoid any things that could get your blog sandboxed by Google. Once your blog is sandboxed, all your previous efforts will go to waste.
Here is how I do blog commenting.
1. Only comment on blog posts that share or discuss topics relevant to your blog.
2. Do not do blog commenting too aggressively. I always limit my blog commenting to maximum 2 per days per blog.
3. Do not comment on blog posts or articles that are more than one month ago.
4. When commenting, ensure that your comments are relevant and do not use same comments everywhere. Try to make your comment original and personalized.
5. Remember to leave a link to your site or blog.
I personally experienced increase in PPC income after blog commenting.
