Traffic Drop from HCU Update. Need Advice

My online gaming website got hit by the September HCU update, traffic is going down day by day and reached to 60% loss. I have more than 7k games (which can be played online) on my website and after the AI revolution, I started writing the content using chatgpt. So there were almost 1500 games for which I wrote descriptions using chatgpt. I already rewrote the content using human writer for almost 700 games and there are still 800 games with AI-generated content (I am not working on human writing further as most SEOs are saying that ranking down is not happening because of AI content).

Search Result Performance:



The website is multilingual and has a total of 11 languages (including English) versions of URLs such as:
Abc.com/en
Abc.com/es/
Abc.com/ru/
Abc/pt/
Whenever I publish a game in the English version, it automatically generates 10 URLs of another language version (ex. Abc.com/es/game-name/), and each version has translated content of the English version. <link rel="alternate" is added within the source code of each URL.

25k URLs are showing under “Crawled - currently not indexed”. Most of the URLs are game tags and game pages from other language versions. However, some URLs are already indexed and it is still showing on the list. It seems because of the crawling budget Google has now stopped crawling so much of pages and this is the reason for the ranking down of my website. Will it be a good idea if I redirect other language versions of URLs to the English version and keep the English version of URLs only to reduce the number of URLs on my website? Will it help to recover my website ranking?





I also noticed that total crawl requests is also going down as you can see on the screenshot:



Are all these the signals of my overall ranking down?

Yes, you can see you were hit by Google update in December and again now. This is quite common... Once Google "penalise" you it will penalise you again during the next update. Nothing to do with your crawling. This is the first stage: Denial. The common question is "Why?" "What is the reason?" "something must be wrong with my site"..... etc... Nothing wrong with your website... Google just doesnt like it any more.

Your site isn't the only one in the gaming niche i've recently heard of being hit by the new HCU extended update.

Suggesting you to wait for one month. Since Mine Got hit and it was on a lower scale and less competitive keywords than you I think. My keywords are getting back in ranking. I did few changes in on page of my website though but not major one's only title and description + some alt tag for images changes in major ranked pages.

Consolidating multilingual pages could help, but don't redirect - improve them. The 'Crawled - currently not indexed' status often points to content that Google doesn't see as valuable.
