First off, technical SEO isn't as intimidating as it sounds, but it does take some investment to get right. Having a solid On-Page SEO strategy is a great place to start, as these two aspects of SEO go hand-in-hand with each other. Technical SEO involves all of the background aspects of SEO that search engines still care about. Finding and addressing web crawler errors, 404 pages, redirect problems and anything that's not directly related to content are all part of Technical SEO. It's laying a strong foundation to give your content the best chance it can have to rank for relevant keywords and phrases.
