Quick article to see how you can (and you should) add a google sitemap to your hexo blog.

There is a plugin for it that will do all the hard work for you.

Go ahead and install hexo-generator-sitemap with:

npm install hexo-generator-sitemap --save

Then add the path to your `sitemap.xml` in the `_config.yml`:
# Sitemap
path: sitemap.xml

Regenerate your blog and check that a sitemap.xml file has been created at the root of your blog.
