This is called keyword stuffing my friend. It won't work and it will get your site BANNED eventually. So, don't use this tactic. never!
It might work for some search engines for a short while but it is just a matter of time before you'll get banned.
True, the results that you'd get would only be short term. If you want long-term results, you should post Search Engine friendly content regularly.
