Yahoo has upgraded it’s database and claim to have over 18 billion pages indexed, all this is while Google has only 8 billion.
However, is the bigger really better? Yahoo obviously thinks it is. While it does not say much to the average Joe searching for socks, it seems as if it is a powerful marketing tool for Yahoo. They’ve announced that they are ready to take on Google at any time as to their index size.
It sounds reasonable that the site with the bigger index would most likely have the better results, but the problem is that it is not that simple.
This is my view of it, there is plenty of shady webmasters who publish hundreds of thousands of spam pages into the web on a daily basis. Google has learned to deal with them and ban them within days of their release. Yahoo, however, seems to still be struggling with these pages and is listing many of them high up in their serps.
So, how about worrying about bettering the results before worrying about the size. At the end of the day, if you cannot provide me with quality results, I don’t really care how big your index are. Some may say that “Size doesn’t matter, but it is about what you can do with it”, this seems to fit here as well.
