In your chiropractic website marketing, you’ll no doubt consider submitting your site to directories at some point.
Directories can be a great way to increase your link volume and improve your search engine rankings. However, not all directories are created equal. There are some directories called "link farms" that are notorious for letting anyone and everyone put their site up. Because of this, Google will often not reward a submission like this and might even punish it.
If you’re not having a professional submit to directories for you, then it’s best to stick to relevant directories for your niche. For example, you will be a lot more likely to get results from submitting to chiropractic, health, and medical directories than places that have every category known to man.
