The varying factors of SERP in Yahoo regions
 

I have produced and initiated a new website within the sphere of Yahoo. I have made a straightforward URL address for this website, which is easy to memorize. It contains all the needed keywords which are at par with my business. I am quite thrilled about this website and foresee a profitable response from the many visitors. Though all this while the site was moving smoothly, all of a sudden I noticed a setback. The SERP numbers differed a lot, each time the Yahoo region was changed. This will surely create chaos in my website. The urgent need at this moment is to get rid of this confusion and to imbibe a permanent and an exact SERP for all the areas. I would like some sound advice regarding this.
