I am trying to rank in the SERP's for the query "t-slot aluminum" or "t slot aluminum". I was beginning to see some progress and peaked at a position of 15.2 on August 11. Since that date, my ranking has incrementally reduced. I saw the biggest drop on August 15.
I have done nothing significant to reduce this ranking. The only thing I changed was adding/removing a Facebook pixel. Over the last three weeks the pixel is no longer in the page's file.
Does anyone see what could potentially be wrong? I have no errors in Search Console.
Update:
This has actually happened to several queries for my site. I was looking on SEMrush today and saw there was a Google change seven days ago. This is where the majority of my page ranks dropped.
The message shows that it has to do with page reviews. My site does not have any product/service reviews because it is not applicable.
Why would this affect me so much?
