I'm building out a new web site called findonlineschools.com and I've just started trying to get more search engine exposure. Obviously the phrase "find online schools" is important to me for search engines, so I was suprised to see that I was the 4th or 5th result listed in the Yahoo search results for this phrase... but then when I went to work the next day and I'm no longer on the first page on that computer - so I'm on the first page here at home (comcast) and not at work (dsl through qwest) - has anyone seen this sort of difference in page results on Yahoo? Is my ISP caching results pages? Am I hitting different Yahoo proxy servers that get updated at different times? Any answer / advice would be greatly appreciated...
