Welcome to the Q&A Forum

This could be for a number of different reasons, it could be because of an algorithm update.

It could be because of a penalty which might have been applied.

However, we seen this with a fencing company, and this often when really good quality backlinks get deleted, and then the algorithm adjusts where your business should ranked because some good links may have been deleted?

This could be for several different reasons, that your business has noticed a drop in SEO performance, it could be because of an Google algorithm update.

It could be because of a penalty which might have been applied? So do need to hire an SEO company to check this.

However, we incurred this with a fencing company, and this happened because good quality backlinks were deleted. Then, the algorithm adjusts where your business should be ranked because the links being deleted.

Impressions don't really mean much at all, as Google often experiments in terms of ranking sites for new keywords, then decides they are not relevant and takes the rankings away again. What we really need to see is 1yr+ of traffic (Google Analytics) and Clicks (Search Console). Even that may not be enough to define exactly what's going on

The site is mainly tagged with the FA language, which is Persian. AFAIK (as far as I know) most Persian people live in Iran, which used to be called Persia (and which is still named Persia by some people, though on the international stage the nation is referred to as Iran)

Right now there's a lot going on in the news between the USA (where Google is based) and Iran. It does make me wonder, does make me consider - could that be part of the issue? Obviously it would be impossible to gain clarification but...

One thing I know, is that Google is foremost an American company, and that right now the USA has "engaged in a campaign of maximum financial pressure on the Iranian regime and intends to enforce aggressively these sanctions that have come back into effect" - source

Who knows what's going on behind the scenes. Right now, Google is really clamping down on 'soft' medical practices within their SERPs which we know from all the YMYL / Medic updates. I know that Google only has limited presence in Iran (as you can see there, they won't even give Google-Iran a TLD, they use parameters in the URL structure to sort of generate a relevant page). This could in part be due to internet censorship in Iran. We know that even the app market, Google Play is extremely locked down in Iran

Without taking sides or making any judgements on the international level (something we wouldn't do) - it does seem that Google have difficulties operating in Iran, in the same way that they operate in the West. The USA is clearly sending signals to Iran right now on the international stage (which are also being returned) - as such, it's not hard to see that an Iranian site (especially one with potential Medic / YMYL issues) might fail to rank on an American search engine

Your site seems to use the "Netmihan Communication Company Ltd" ISP, which would confirm that the site is based in Iran (rather than just being built for an Iranian audience by those who may be external to Iran). I have the city down as Rasht

Taking no sides here, it's possible that your site has become a casualty of international conflict (at least on the communication and economic level) and additionally of YMYL / Medic updates, which may have stung you regardless of your location

Hope this is helpful to you, hope you will have a great day

Hi

You cannot tell from that set of data what the issue is.

Have you used site: to check how many pages of your site are being indexed?  Does that number correlate with with the number of pages expected to be live on site?
