Hi,
There was a drastic fall of the keywords for my website. Upon checking, for certain keywords the Rank Checker shows the positions where as the manual search in google doesn't show the ranking at all. Checked for multiple locatios. What could be the issue? How to get this sorted?
I think Google Search Ranking is the best, You didn't trust other seo tools. When you follow the Google whole strategy you can top in the search engine.
Never fully trust an SEO tool about ranking. They usually make a very global country-based rank check. If you want to truly check you rankings use a VPN service and a manual check. In the best case scenario, you will have a friend from that area that can check it for you using un-personalized search. I have had 4 different rankings for a keyword based on ranking checks from 4 different cities.
The main reasons for users getting varying results in Google are location, personalisation and algorithm variations. Google's aim is to deliver the most accurate and relevant results for each individual search engine user, so the variations are entirely intentional.
