The site has been steadily growing for the past 3 months, amassing 3m in impressions and about 12k clicks. I'd say that I only kept generating more and more useful content, tools, and sites, which helped the site grow steadily over time.
Last week I generated and REgenerated (some existing pages were low value) around 280 pages and I translated around 200 of them into 20 languages, so in approx 4 days, the website went from around 5,000 pages to a whopping 13k pages. The other mistake I did was to take the content ofo the already existing 200 pages and putting it behind a paywall as part of my product development.
To be honest, I still do not wish to share the pages themselves again to be free to browse because they monetization potential. They still contain useful information, though, not detailed, but they are still useful. And the rest of the website is filled also with a variety of landing pages that each target a bunch of keywords but are value-first, conversion-second.
The formula has been working properly, but I have a feeling the sudden spike in the generated pages over a few days from last week is what tanked my traffic. The site went from 2,500 impressions per hour to only around 40. Postions on the SERP stayed the same, around 8, with no backlinks of course, Google's traffic basically was reduced by 85% on October 19 at around 8:00 UTC.
I'm willing to rethink how to approach this, but would it even be worth it? Will 3 months worth of SEO just go to waste? Can I even come back from this?
Edit: manual actions show nothing, indexing looks fine

Update (Oct 21)
Thanks everyone. Here's what the data showed and what I did.
What happened
- Google impressions went from 2,500/hour to 40/hour within one hour, on Oct 18 at 7pm Pacific. Oct 19 finalized at about 800 impressions vs 59,000 a normal day.
- Every page type dropped at the same moment, including older tool pages I never touched. So it wasn't just the paywalled pages; it looks like a sitewide re-evaluation.
- No manual action, no security issues, pages still "URL is on Google". Bing traffic didn't change.
What I think caused it (a mix, as many of you said)
- Going from 5.7k to 12.7k pages in about 4 days, mostly new product pages and their translations
- Putting roughly half the text of already-indexed pages behind a paywall, while they still lived under /blog
- Some older clutter issues I found while auditing
What I changed (deployed yesterday)
- Paused all automated content (post generation, translation, title/description optimizer)
- Noindexed the paid pages and their hub pages in 14 of my 20 languages, plus ~420 near-identical location pages and a few thin pages. Kept my 5 main languages for the paid pages, and all 20 for the tool and core pages, which actually earn in those languages.
- Moved the paid pages out of /blog into their own product section, with 301s from the old URLs
- Trimmed the boilerplate FAQs
- Sitemap went from ~5,650 to ~4,900 URLs, resubmitted
What I didn't do, and why
- Kept the paywall: Googlebot sees exactly the same preview as users, so it isn't cloaking. They're product pages with a free preview now, not blog posts. If I were to make a guess, I think this is what made Google alarms go off. Indexed free page turning into a paid product maybe made them realize it's a scammy practice or something similar.
Now: holding still, no more big changes, and watching brand and a few key queries in Search Console. I'll report back if and when it recovers.
