Here are Six Quick Tips:
1/ Pick a Theme that you will use consistently and will guide your content.
This might be your industry specialty, your geography, or your views on the industry in general.
2/ Try to make a new blog entry every day - even if it's a link to a story someone else wrote that you want to recommend.
3/ Use "Key Words" in your title - words that might appear in a Google Search (ie San Diego Real Estate)
4/ Try to write and spell well.
5/ Have an "Angle" to your stories - something is good or bad, is too expensive or cheap, is a good idea or bad. Defend your opinions with facts.
6/ If someone comments on your post, respond. Start a conversation.
