1. Am I correct in saying that Search engines metainfo uses the link to determine whether to use the meta-data?

Therefore, if my URL is staging.mywebsite.com there is no point in filling in the information using JSitemap because that URL will change when I go to the live site?

2. I assume the information shown is article related, so there is not a menu item etc.

3. what is the performance hit from using this system? I know it is an override system, it would be good if we could see the difference perhaps. Perhaps if there was a way to edit things from the SEO spider window? Currently, it shows all articles, it would be better to filter them in a priority order. Maybe some filter dropdowns would work?

1. Articles that have a main menu item link
2. Articles that have any menu item link (maybe?)
3. Articles that have no title/description
4. Articles that have no title
5. Articles that have no description
6. Articles with a short title
7. Articles with a short description
8. Articles with a long title
9. Articles with a long description

It is quite tempting just to hit "autofill" because then things are populated already, but since this is meant to be an override system, that makes little sense. That is why I have asked about the performance hit using this plugin.

Best,
