Overview
A sitemap.xml lists URLs you want crawlers to discover. This generator builds that XML from URLs you provide so small sites can upload it to Search Console.
It does not crawl your site for you like a spider. If you paste 300 thin URLs, you are asking Google to look at 300 thin URLs. Which is the opposite of the AdSense quality fix on Mopailor itself.
Include canonical URLs only. Leave out thank you pages, internal search, and duplicates.
