Domain Extension - Net/Org/Org.uk

I've found a few domains which are available in: .net / .org / .org.uk

Im going to develop these sites myself rather than selling, although I may sell them at some point in the future, so the main factor is SEO.

Normally I would go for the .org.uk over the .org for UK SEO, but not sure were people "rank" the .net compared to the others for SEO, and also for resale in the future.

Im tempted to buy all 3 for one keyword, create separate sites for all 3 with totally different content, do the same amount of seo etc and see which ranks the best...taking the top 3 of the front page would certainly corner the market

 

For online marketing then definitely .org.uk but for offline marketing then I would go for .net

.net and .org but more so .net can get ranked nicely but you need tons of content and regular updates and probably a bit of age aswell.

Hope that helps
