XML Sitemap Missing

Your website does not have an XML sitemap - this can be problematic.

A sitemap lists URLs that are available for crawling and can include additional information like your site's latest updates, frequency of changes and importance of the URLs. This allows search engines to crawl the site more intelligently.
Robots.txt Missing

Your website doesn't have a robots.txt file - this can be problematic.

A robots.txt file allows you to restrict the access of search engine robots that crawl the web and it can prevent these robots from accessing specific directories and pages. It also specifies where the XML sitemap file is located.
Analytics Great, your website has an analytics tool.

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 11 blocking script resources and 10 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 11 blocking script resources and 10 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:
