Storing page views as a cookie - good idea?

Question

I'm trying to think of a smart way to roughly measure unique page views of my website.

My first thought was to have a database table recording every hit, but that doesn't get around the issue of the same user constantly refreshing the page.

Instead, I'm wondering if cookies is a reasonable idea (or perhaps a mixture of database records and cookies?).

Something like:

//on page hit

let pageViews = cookies.get('myWebsitePageViews');

//pageViews = '12, 135, 14, 2, 5' <---a string of page IDs

if(pageViews.contains(thisPageID){
    // do not add new entry to cookie string
}
else{
    cookies.add('myWebsitePageViews', pageViews + ', ' +  thisPageID.ToString());
    serverCall.IncrementPageView(thisPageID);       
}

I understand cookies can be deleted or disabled, but generally this would do the job as I'm not looking for strict accuracy. I just need something to prevent the average user from bumping up page views via constant page reloads.

I'm wondering if there's any major issue with this, or any better method that I'm unaware of.

Thanks.
