Well this is going to be a growing list. Technically speaking, Definico should pick up all changes that happen on your website and mark them for you to review. Where it is able to discern if the change could have an impact on your SEO it would highlight it for you. (Bear in mind that almost any change could have an impact).
With that being said, these are some of the things that Definico has commonly detected. Please share / let us know if there are any that it had detected for you.
Common SEO Changes Definico detects:
– Changes to your URL structure (if urls have been added or dropped)
– Changes to the HTML content on any of your pages, specifically META, TITLES, HEADINGS etc.
– Changes to Robots.txt / sitemaps and any special URLs you want tracked
– Webserver behaviour & response
