Perhaps this isn't the most significant of posts, but it's something i chanced upon the other day, so thought i'd mention it. I suppose it could be a decent tip, but i haven't tested it enough to state anything conclusively, however, i now consider this fact! If you can't be bothered to read all my nonsensical bollocks (i can go on and on and on...) then skip to the last paragraph. Right, i have some sites which are in fairly competitive niches, and do all my own SEO, site building etc. Anyway, some background, i don't use Yahoo, and never have used Yahoo to do my searches. As a search engine (for my needs), i've found more useful motorcycle ashtrays. So, a few years ago, some cock allowed a really good domain to drop, it had all my major KWs in it and i moved my old site to this new domain. Obviously it took a while to get it on a par with the old domain, due to age, backlinks etc, but i built the new site with a great seo score in mind and coded a clean as fuck css site (which may or may not be relevent). God i go on! Right, long and short of it is, on a few of my most competitive terms i'm hitting page 2 on Google now, traffic is up 100% on the old site and everything's cool. I have done very little backlink building, only really have links on major directories, DMOZ, BOTW, etc. However, a few days ago i noticed my site was number 1 on Yahoo, for nearly all my terms, if i wasn't number 1, i was top 3. The point is, I completely dominate my niche on Yahoo and the only valid explanation is the domain. So if you want Yahoo traffic, only about 5%-10% of my traffic, then load that domain up with your main terms, because Yahoo clearly gives massive strength to rich domains. Has anyone else noticed this?
