This question already has an answer here:
I'm taking Spanish lessons from a school that uses a domain name
sol-spl.com (not the actual domain), where
sol is the name of the company, and
spl stands for "Spanish private lessons".
I was thinking that it might be much better for their search rankings if they used the domain
sol-spanish.com, since every search for spanish lessons is going to use the keyword
spl isn't likely to be used.
Will switching domains like this likely have a positive impact on their search rankings, and is it a reasonable thing for me to advise them to do?
