I have a ranking issue.
[link removed by moderator]
The main keywords are "hängmatta" (hammock) and "hängmattor" (hammocks). My site ranks no 1 when doing a Google search for "hängmattor". The problem is when searching for "hängmatta". Until 2020 the ranking was always on the first page. Then the "hängmatta" search dropped continuously to ranking around no 115 today or even worse.
If I combine "hängmatta" with "Brasilien" (Brazil) or "brasiliansk" (brazilian) it ranks no 3. The problem is when searching for only "hängmatta".
My ranking today:
"hängmattor" (plural, hammocks): #1
"hängmatta" (singular, hammock): #115
hängmatta Brasilien: #3
hängmatta brasiliansk: #5
köpa hängmatta (buy hammock): #15
handla hängmatta (shop hammock): #10
IMO title tags, meta descriptions, alt text etc looks OK and I don't there are no keyword stuffing. I understand that Google treats singular and plural different, but the difference is just too extreme.
I would be happy if somebody have some advice on what I could try to get my site to go back ranking good for "hängmatta"?
