Our websites are built to optimize SEO, yes, but that doesn't mean you don't have a part to play !
One of the most important thing you can do to help your business is write your own, unique content. Google likes to see fresh, new content, and if you have the same MLS description for your listings as the every other agent, well it will be hard to differentiate yourself from the competitors.
Write your own descriptions for Listings, more detailed, more customized to your knowledge of the area, more relevant to your clients.
This can be applied to your website as a whole, not just listings descriptions.
If you have a Buildings module, you can also customize the descriptions for each Building.
The blog is perhaps the most useful tool. Take time to write your articles. Write frequently, so that Google always discovers new, fresh content. Write thinking of your audience, think of what they would like to read about, and what knowledge you have to offer in that area.
Since we manually set up your Wordpress blogs so they're integrated in the the rest of your website, any content you write or clicks you get will improve your SEO, unlike standard Wordpress blogs.
Finally, make sure to structure your content in an articulate, appealing way. See this article for more details in this article.
