Generally speaking, you’ll want to take into account the scale of the changes you made, by the potential impact of the changes made to guestimate your timeline for impact.
If you changed 1 word on 1 page, low scale, low impact vs 100 changes on 100 pages you have different timelines.
That’s why it’s generally best to develop “best practices”, and make regular sets of updates and changes over time to keep the ball rolling vs trying to reverse engineer one particular change on=site = one particular rank change.
Be Aware Of Google’s Spam Deterrence
You should know that there is an INTENTIONAL up,down, down, up up, down amount of change to a particular page that’s put into place to prevent SEO spammers from gaming the algorithm. When you make a change, don’t expect to see a linear progression from position 32 to position 4. You’ll start to see fluctuations, up and down, just know that it takes time to generally reach a more stable position.
Again, that’s why you want to develop a longer-term approach that employs best practices, with a minimum requirement of watching for your eggs to hatch.
