Crazy Myth #4: Posting listings on my blog will water down the rest of my content
This myth actually isn’t so crazy. It’s a real concern that many real estate bloggers have, and I don’t recommend that anyone write a post about an individual listing and include it with their regular blog content.
So, here is how you get around that… The solution I’m sharing can be done on any platform, but I’m going to show you how with wordpress.
The best solution for this problem is to create a specialized category just for your listings. Then, you want to tell wordpress (or your platform of choice) not to include that category on the home page. You are essentially just excluding that particular category.
You will want to place this code in your index.php file to tell your home page not to include the category you choose.
Here is the code: <?php query_posts(’cat=-13′); ?>
You will need to change the category number to make it work (where it says: “13″). To find the category number, go to >Manage>Categories, then view the category number you want to exclude. For more detailed instructions on this try this wordpress tutorial.
