A healthy community requires everyone to join in. Instead of only focusing on your business, why not focus on other people in your niche as well? Show a little love, and it’ll come to you. Perhaps you read an interesting post that was informative, why not tag that person and give them thumbs-up for a job well done?
If you do mention someone in a post, do not forget to tell them about it. E.G, “I recently happened upon NAME OF PERSON’s website where he/she was talking about XYZ.” It’s polite to send them a quick “Thanks” note with a link to your blog post attached. This way, you’ve helped promote them, and you’ve decently informed them about it. Do not ask for any favors in return; simply tell them that you appreciated their content.
