Does Analytics knock down all statistics?

Question

Google Analytics

Hello!
The problem is complete nonsense and I do not know how to solve it. Can anyone come across? I have a project with an icon finder and google analytics installed. I decided to make a tag cloud for the most frequently asked queries in the search. However, I ran into this problem:
When a user searches for an icon, I add 1 to the total searches for that tag. Then I insert this request into the session so that when the user goes to the second page, or once again searches, the amount is not added. Accordingly, 1 should be added to each keyword only once from one user. However, as it turned out, with each request of the user of the google analytics server, they also give a request to the requested page. What does the request come from different ips and sometimes from 2 or 3 ips per user request and the session is not controlled. every time a different server. That is, if a user searched for an icon one word at a time and went through 10 pages, from 20 to 30 are added to the keyword in the tag cloud, which completely knocks down all the statistics for creating the cloud.
I removed the analytics, and everything was fixed. But I need it :)?
Does anyone have any ideas how to solve this?

Answer 1

Filter search engines by user agent.

Answer 2

changing the state by ordinary GET requests is evil, you never know what other bots will run in and start “clicking” on everything in a row.
send a POST request to your statistics script from the search results page using javascript.
about the same as the analyst himself does.
