Search engines results pages are known as SERPS. Many webmasters keep an eye on how well their site is ranked or positioned on SERPS because good or bad rankings can have a major effect on the amount of traffic a website receives (in other words, the amount of people viewing a site).
All search engines would rather you check your website’s rankings manually, if you are going to check them. Automated programs jam up their servers with too many queries.
How to Manually Check Your Rankings
Checking your site’s rankings manually is easy enough, if a little time-consuming.
If your website does not appear in the first or second pages of results, it’s unlikely that you will be getting a high volume of traffic (searchers) visiting your website.
