Rankings dropped sharply. What is the problem?

Question

Search Engine Optimization

Hello!
I have such a problem. My site - washing-machine-repair-krasnoyarsk.rf Has fallen sharply in the search results for several key queries. On the first request, it fell from 3 to 8, and on the second request, it fell from 5 to 11.
The site changed over time only in small things (the color changed here and there, the menu changed slightly.) and, just yesterday, I found that the positions sank quite strongly . Usually, as I noticed, Google does not go to extremes, and removes positions gradually, but here it’s just bam, and 5 and 6 positions down. I thought it was Yashka's joke)
Please help me, because I'm new...

Answer 1

And why did you decide that your positions fell, and the positions of competitors did not grow?
And they pressed on.
Well, a banal recalculation of positions as a result of a change in search algorithms.

Answer 2

Well, fluctuations by 5-6 positions are generally the norm. There were search recalculations, during this time new sites may have appeared or your competitors have improved, there are many variables. You need to take specific requests and pages and look at them
