I am a noob when it comes to SEO but I've read that domain names with keywords are very important. My question: If I had a keyword as "plumber in london", which domain would be ranked better for those keywords; www.plumberinlondon.com or www.plumber.inlondon.com I realize I should go the regular domain route, but to start out it would be cheaper to make a bunch of subdomains. Plus, in my campaign the domain name won't have to be memorable or easy to type. My main concern is if I start backlinking, etc. will one be better than the other? Any help would be GREATLY appreciated!!
