Technical SEO is essentially the foundation of your optimization structure. It is important to build with technical aspects in mind so search engines can find and view your Website's content. Having this in place allows for the other aspects of search engine optimization to take form. Why wait until a technical issue on your site causes unnecessary negative SEO consequences? Being proactive and planning in the beginning stages of your build, saves you from headaches and extra work later on. Crafting your site with some technical functions in mind such as, loading quickly, security features given preference by search engines, responsive design, removing extraneous content, and sitemaps allows you to employ expansive web marketing techniques and reach your target audience effectively as you go.
Technical SEO is the optimization of your site and server to help search engine spiders crawl and index your site. Search engines give preferential treatment to websites that are secure, mobile-friend, and that load quickly. Additional technical SEO includes sitemaps, schema markup, and ensuring that your site contains no duplicate content. The reason it's called technical is that it has nothing to do with the content of the website itself, but rather how the website is structured and how it performs. The slower a website, or the fewer devices that can display the content, the lower the website will rank in search engine results.
Technical SEO is often considered the foundation of SEO. This is because sites that are fast, secure, and mobile-friendly rank higher than those that are not. Great content helps, but if the user experience is missing, your site will not rank as well as it could.
Like the foundation of a home, once technical SEO is performed there is a high chance you won't have to worry about it again.
