1. Improve your search engine rankings.
Written content is still king on the internet. When you write blog posts on your subject you are creating new content for search engines that is rich in keywords. When you do it regularly, the search engines will notice and will update your rankings quicker. When people comment on your posts, or link to your posts, the search engines notice and add value to your keywords. The best long term strategy for search engine optimization is to have an active blog on your keyword subject.
2. Expand your markets.
You may be locally famous. Your family may have owned the best store in town for several generations, but nobody outside your local area probably knows. The internet lets you reach the whole English-speaking world for the same price as reaching your local zip code. When you write blog posts on your tips for raising roses, or your advice for first-time home buyers, it can be seen by anyone. A blog lets you develop a following way outside your local area.
3. Make an educational sales presentation.
If you sell snow-cones in Texas in August you probably don’t need a blog. It’s hot, they buy, business is easy. But if your product or service requires more education and explanation before they pay, then a blog is an excellent low-pressure way to educate your prospects. Your blog lets you explain what they should look for in a vendor or product. You can tell success stories of clients who chose wisely, and horror stories of those who paid too little — or too much. Your blog becomes your low-pressure, always available pre-sales consultant.
