I'm not sure what to use blah-blah-blah-blahhablahha-dedah.domain.com or generic9281.domain.com Is is better to have keywords and look spammy, or have no keywords and look half decent (like numbering each subdomain)? This is for an automated system so I can't choose each one manually. It's not spam, and I don't want it to look that way.
I have seen quite a few sites with blah-blah-blah-blahhablahha-dedah.domain.com .domain.com and yes it does look spammy. why not go domain/blah-blah-blah-blahhablahha this will be the best option.
I used to do that... although for this project, it is more effective to use subdomains. I think I am going to just use the long subdomain method, except place a fair character limit.
