High admin-ajax.php requests

I’ve tried to work out this issue with my web host but they have said it falls outside of their support scope and that I should get WordPress support. Yet, their reps have all been telling me that I need to reduce my ajax requests.

I want to preface this by saying I’m not a developer or overly technical.

I get around 3000 organic visits to one of my blogs per day. Looking at the URL requests in a 24-hour period, I see a normal distribution of requests to various articles on my site. But, by far, the most URL requests go to admin-ajax.php. For example, I’ll see something like:

(/wp-admin/admin-ajax.php) – 5663 requests
(homepage) – 398 requests
(most popular articles) – around 80 requests each
and so on…

Basically, I want to know if this amount of ajax requests is normal because after investigation, I found that a typical page on my site will send around 2 ajax requests each (one is related to a plugin called Thrive Leads, and another is called mts_view_count which I think might be related to my theme). 1-3 requests per page load doesn’t seem unusual at all.

My web host couldn’t answer my questions, so hopefully someone here can. Is it not normal to get this amount of ajax requests per day if 1-3 ajax requests are made every time someone visits my page and I get the amount of traffic I stated above? On top of that, I suppose requests would be made when I’m working on the backend.

Also, would this normally cause high CPU usage?

Thanks,
Paul
