There are lots of 3rd party articles that already answer this question. Here are some links when searching for "adobe analytics utm" in Bing: https://www.bing.com/search?q=adobe+analytics+utm

If you're using the direct JavaScript implementation with AppMeasurement.js, then the rollout happens only when you update the base AppMeasurement.js library in your website. (You can get the latest base AppMeasurement.js library from your Adobe Analytics admin.) So if you don't deploy that updated AppMeasurement.js library, then your Analytics implementation will still be on whatever version had been deployed previously. If you're using AEP Data Collection Tags (a.k.a. Adobe Launch) as your tag...

If you need your HTML to finish rendering first before a Rule runs, then in that Rule, use the Core > Window Loaded event. That event will trigger only when the browser has finished loading the window's document, including HTML, scripts, stylesheets and images, i.e. it is equivalent to window.onload().

Such batching is only available with the Mobile SDK for mobile apps. There's no such batching available with Web SDK. Adobe charges you for the number of hits, which normally corresponds to the number of page views and custom links that you're tracking. So even with the Mobile SDK, Adobe still charges you for the actual number of hits in the batch, regardless of the number of times their endpoint gets hit.

Then your problem is most likely related to the eVar's persistence setting, which @VaniBhemarasetty had mentioned in her reply.

Well, what you're doing will still cause the result of AA reporting page names other than the ones associated with your "product tag" dimension. Since you're using a Visitor-level segment, you're saying "return all data for all visitors who had at least 1 hit that contained my product tag". And since a visitor can view pages A, B, C, X, Y, Z, etc, AA will report all of those pages too. I suggest that you use a Hit-level segment instead.

Besides what @VaniBhemarasetty has mentioned, check your segment's definition too. If you're using a Visit-level segment, then it will return all data for all visits that have at least one hit that match your conditions. That would also include all of the page names that had been viewed in the visits.

1. Add this script in the of your page with async. 2. What are you batching? Can you elaborate on this question?
