Justin Tadlock 2 years ago Updating the theme to do something differently is going to have little to no impact on your search rankings. Ultimately, here are the two most imporant factors: Content is king. Your site must have well-written content that people find value in. Links from other sites that rank well. There’s a bazillion other micro-optimizations that you can do. Yoast SEO or the All-In-One SEO plugin help with that. Even with all that, your site is competing against others who are all wanting the same thing that you want. And, the competition can change daily as new sites are added and old sites are removed. There’s a couple of things that you have real control over: The first is your own content. Write for humans and not for machines. For example, I just noticed the “AORTIC DISSECTION VIDEOS” widget in your sidebar. Of course they’re “aortic dissection” videos on a Web site about “aortic dissection.” You don’t have to tell me that. That seems like keyword-stuffing, and Google definitely can and will drop your rankings for stuff like that. “Videos” should suffice as the widget title. I’m not saying that you should definitely change that title. I’m just saying to think about your readers more than whether a search engine will think something is good. The second thing you have control over is sharing your work with others via social media and other related sites in the same field.
