Will replacing 'to' with 2 or 'for' with 4 improve my site's PageRank
I am about to register a domain name (suppose) someone.com (with proper spelling), in mind targeting the keyword "SOMEONE". But then I discovered on 'google keyword research tool' that not this but a typo "SOME1" seems to be more popular and people search this significantly more often than the proper keyword. And luckily someone.com and some1.com both are available.
I understand that I can register both the domains, but I don't know on which should I keep my website and redirect the other one. Should I make the typo "some1.com" my base site? But that's a typo.
P.S., my site has a totally relevant content and not just keyword targeted worthless site.
What do you guys suggest? I am confused. How would that affect my SEO ranking??
EDIT: Because the competition for the keyword I am targeting is fairly low, I think nevertheless whatever domain I choose, it will appear on the search engine first page.
