Every time this happens I just have to shake my head in disbelief.. I often buy some domains with plans to build out the sites later.. Sometimes I'll quickly slap something up on them with some keyword rich text and do a quick index blast just so google will index them and will "know" what it's supposed to be about.. Plus it will "age" a little. More often than not though I don't have a lot of time so I'll just put up a PHP index page with a proper site title (the domain names and the site title always have the keyword phrase in them), the site title in an H1 tag and then just the date near the bottom using php so it changes every day. The "sites" with just the H1 tag almost always end up in the top 10 for a few days at least.. In fact I've got one that been in the top 10 for months now.. I'm almost afraid to actually put something real on it now as I just know it will drop in the SERPs until I get some real backlinks to it.. LOL So the lesson here.... Make sure you use the H1 tag for your keyword titles etc. It's still important to google.
