Multiple domains for one website?

Not all tactics regarding Search Engine Optimization (SEO) guarantee success. The basic ones like title tag, meta keywords and headers to name just a few may or may not affect your site's ranking. Some tactics though at first blush may seem like a good idea.

Multiple domains for one website though is a very, very bad idea. Why?

1. It depicts you as a schmuck who hoards domain names and asking people to pay gadzillions when they wants to buy them later.
2. Nobody likes lazy ass with duplicate content on different websites.
3. Your pagerank, visitor count, and AdSense revenue goes down because of #1 and #2 above.

So there, don't make multiple domains that points back to the same page.

Next time you have an Eureka! moment, consider stepping back and think thoroughly about the whole thing, lest you get a surprise in the form of an Ig Nobel Prize.
