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
Missing
We didn't detect an analytics tool installed on this website.
Web analytics let you measure visitor activity on your website. You should have at least one analytics tool installed, but It can also be good to install a second in order to cross-check the data.
