"in google webmaster tools we have targeted the shop domain to United States, which may be another factor"

That's your problem right there.

If you tell google that your site is aimed towards the U.S market, you will have to put up with "Unites States" next to your site.

Sorry but there is no way around it, that's google for you.

Go into WMT if you have an account and resubi your sitemap for websitebuildersword.com, or simply google suggest site or something similar and find where you can submit your site to google again.

It should get indexed again anyway, because you should have some links out there somewhere that the bots will detect and go to your site from.

Quite a big stuff up though, on your programmers part.

Good luck

The seo moz stats for a site is not the exactly same as what google uses to determine authority/trust so just because one seems to have more authority does not mean google thinks it is more relevant.

Hence why even some new sites with minimal back links can outrank some very trusted sites on the same topic.

Welcome to the wonderful world of seo, strap in and get comfortable because it's a never ending journey.

All the best
