I read an article on "Content Curation" on Search Engine Land. I've never heard of "Domain Sprawl" before. Here's a quote:
<<Most SEOs that have been in the industry for a while would largely agree that overall domain SEO performance can be generalised to be a balance between the total backlink profile of the site (its “Authority”) and the total number of pages indexed on the domain (the total “Domain Sprawl”).>>
Basically he is recommending pruning out old pages of your site, or putting in canonical links to newer pages to trim down this ratio.
It's a new thought, would be a lot of work...can anyone tell me if you think it is worthwhile? I have the feeling it's a time sink.
