New Site or Continue With Old?

Keep the domain because it weights a lot and try to see what a penalty doctor says (I think you can find something in BST).

You should really think hard about it.

Aged domain rank better than new one.

Have you tried making change in the link structure?

Hi lol-blaster, I have made some structural changes only recently. The site runs on wordpress and I removed instances of tld/keyword/red-keyword/ to just tld/watered-down-red-keyword/

Also I removed the breadcrumbs as they were repeating the parent URL as well. It's too soon for any of these changes to have any effect though. Also title are now changed to be less direct and more watered down, including other variations of longer tailed phrases as well
