I have a question about what domain I should use as the main domain. The domain consists of an abbreviation and a noun. For it to be grammatically correct it should be written with a s in between the abb. and the noun in that language. Right now we are using a different domain and from the analytcis everyone that have been googeling our site has come from googleing the abbreviation the noun but leaving out the s. I am planning on buying both domains but I was wondering what would be the best user experience to use as the main domain and just forward the others.
To keep it anonymous lets say the abbreviation is AAA and the down is class.
Should the main domain be:
AAAsclass.com or AAAclass.com
What are the pros and cons?
