To improve the overall technical SEO, you have to note some factors. Javascript, XML sitemaps, Thin content, Canonical tags, URL structure and Site architecture are some of the parameters. A poorly designed structure is never going to improve your position. Always employ a flat and organized structure for the website to be maintained. URL should be also well shaped to optimize the site according to your needs. Don’t have any dead links around and no duplicate content is to be used. https://www.ecostreamit.com/search-engine-optimization
