I'm thinking about using my last name as a domain name but all extensions are taken. I'm thinking about adding a 1 (number one) to my last name (it's available). Should I add the 1 in front of at the end of my last name? Thanks for your suggestion.
I always stay clear of numbers because look when you share your URL with others via say a personal meeting or a phone call.
The domain name is in your example your last name and the number 1 you begin a difficult future for your success. Is it a "1" or a "one".
Then there is the what is the relevance of of the number search engine talk time, this is why we do not use our personal name even though I own it as a .com LanceConway it is better to have at least a second redirect domain name that is explaining what your business does for an example i could have my LanceConway for my business but also have a .com like computerrepairexpert (which I am not) so the site content and the domain name look to belong together. Just the way we do things.
