HELP - How should I track keywords, KPIs?

I do a custom report in Google Data Studio for each client. It pulls data out of many sources including GA and GSC and allows to customize your dashboard for each project individually (you can add main KPIs your client wants to track). I also like the fact that it can be branded and other visual stuff which makes it look like you are an agency, not a freelancer This is pretty much what I do.

I'd think the very first place to ask is the place that hired you. How do they want it done? What did they do in the past?

I will all in all spotlight less on catchphrase rankings and more on traffic and introduction pages. I center around the inquiries in request support and look at examples. I moreover look at the traffic on subdirectory level to get a progressively broad perspective. I furthermore center around usage signals, backlinks, social balance, changes, and diverse signs. I focus on landing pages that generate the most conversions. I always compare them year over year and month over month. I want to see if they changed. If they do change I try to understand why that may have happened. It generally comes down to was it me, Google, or my competition. These signs have an impact (prompt or underhanded) on Google and all around online accomplishment.

Keep in mind forget that Google is customizing indexed lists. Besides they are continually taking off positioning equation changes. Regardless of whether you roll out an improvement to the page, it doesn't mean it is the explanation behind any Google traffic change. A few pages that don't consistently change content and have few backlinks may be crept by Google rarely. It's conceivable Google hasn't seen a change on your page yet changed their positioning equation. There are such a large number of moving parts to this circumstance.
