TLD or top level domains are the .com/.net/.org endings to a domain name. These are called gTLD or generic top level domains and are simply endings that are not country coded. Whereas ccTLD ones such as: .co.uk/.fr/.us etc are country specific domains and will be better suited to websites that only have a single target region.
Anyway, there has been a huge myth surrounding TLDs and if one type ranks better or worse than another. I mean you always see .com/.net/.org’s in the top 10 results on Google for keywords and you never see any .info or .me domains, that must mean they rank better right? NO!
The type of domain you own as long as it is a gTLD makes no difference to your websites rankings. The myth that the 3 most popular gTLDs (net, com and org) rank better than any of the others is simply a myth that could be proved with numbers but not with ratios. What I mean by this is 99% of all such results (excluding ccTLDs) will have (net, com or org) search results.
If we take the search term SEO for example (for my search of SEO) I get: 5 .co.uk results, 3 .com ones, 1 .org and 1 .net. Same for page 2 and out of the first 7 pages. That’s 70 results only 2 were different from the first page and that was a .me link and a .ac.uk (which is the UK version of .edu). So this is how this myth was born, because its easy to prove.
BUT NO! If you divided the total number of (com/net/org) domains vs others and then related it back to search results, it would be clear that the rankings difference is minimum and only happens because people have more .com domains than any other. Its a ratio game not a numbers one!
Now to completely contradict what I just said:
I would recommend trying to get one of the more common gTLD’s such as the .com, net or org ones simply because users aka humans are more used to going on it so they will be more likely to choose your website if it is a .com than a website that is a .ws or a .info one, it is simply user preference and makes no difference at all to overall rankings and has nothing to do with the SEO of a website. Hope that helped guys and as always: Stay Optimized!
