advice Plural Or Not?

imo
1 word products > 1 word product (e.g: Cars vs Car)
Adj +prodcut or object > Adj+products (e.g: fullmoon vs fullmoons)

Generally, one version ('s' or no 's') will clearly sound better and/or be grammatically correct.

I will always go for the better of the two unless it is a killer word or phrase. But for just over $8 a year to register, including free privacy, means I will usually get the matching name in the alternate spelling.

Often times the singular can make for a great brand that has nothing to do with the product described. Example being Apple.com.

Although, if you were selling shoes, the plural would be better. Example being Shoes.com.


Of course, as always, IMO........

More often the singular is more valuable, but there are many exceptions. As @Mister Funsky says it depends which sounds better. If there are already past sales that can guide you. If both sound correct, I often use Google results to help guide me re which is more common (and in most cases more valuable).

Get them both if you get the chance. If sell one after close of sale offer other if not packaged.
