I was doing a Google search for keywords "mrp system". One computer showed my site in the middle of page 4, another - at the bottom of page 8. Why is it such a big gap? I use Firefox on both machines.
do you have different locations set? this is shown on the left of the results, normally set to auto-detect
It's the web browser that you're using. If you use FireFox, then you might view different results that you'd normally get on Google Chrome.
yah it is on the browser that your using. The technicality on what happen to your site is really basic. But if you want to assured you listing then use a tool that will give directly the page of your site.
