I used to update some sites in the renewable energy area with press releases. I still have the domains but didn't do much about it during the last few years - so visitors are very low I reckon.
The sites were lacking of a monetizing concept - I sold some links and get some bucks each month.
Looked into lead generation for local solar businesses etc. but I guess I first need visitors with a fresh content strategy and I'd need some more ideas on how to monetize the site. Mostly I started them because I've been a bit interested - but far from an expert on anything there :-S
Any ideas on this one?
