XML Sitemap Missing

Your website does not have an XML sitemap - to make it easier for search engines to find your pages it is wise to generate a sitemap.

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 efficiently.

Go here to know more on how to set this up: http://www.sitemaps.org/protocol.html

If you have a lot of pages (up to 500 pages is free) you can auto generate them here: https://www.xml-sitemaps.com
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.

For more information on how to do this: www.robotstxt.org
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 one in order to cross-check the data. This can be Google Analytics or Clicky.com
