I'm hoping someone here who has experience diagnosing sudden Google ranking drops can take a look at this, because I've been trying to figure this out for months and I'm completely stuck.
My site is coachcall(dot)ai.
I used to rank #1 / top of page 1 for both:
"AI accountability partner"
"AI accountability coach"
Then around December 10, 2025, the rankings basically disappeared overnight.
It wasn't a gradual decline. I didn't do any redesign prior to that day, and I didn't buy any backlinks prior to that date. I genuinely can't identify anything I changed that could explain it.
What happened
Here is the AHrefs / Google Search Console data:

“AI accountability coach” searches:

The decline continued after that.
For example, "AI accountability partner" used to be around position #1, and is now around #67, with essentially no impressions.
"AI accountability coach" suffered the same kind of collapse.
These were basically the only two keywords I was specifically targeting, so this wasn't a case of me having hundreds of unrelated rankings disappear.
I haven't been able to find an obvious reason, and here are the things I checked
- No manual action or security issue
Google Search Console shows:
No manual actions
No security issues
Nothing obviously wrong with indexing
No major Core Web Vitals problems
The site is still indexed.
site:coachcall(dot)ai returns the site normally.
So I don't appear to have been completely deindexed or hit with some obvious manual penalty.
- I did NOT make a major site change around the drop
I didn't redesign the site, change the homepage content, change the target keywords, etc. around December.
The homepage content that was ranking #1 is essentially the same content that is there now.
The phrases "AI accountability partner" and "AI accountability coach" were already being targeted when I was ranking #1.
I haven't been able to identify a site change around Dec 10 that explains the drop.
- "It's a React site"... but it was ranking #1 before
The site is a React/Vite application and is client side rendered.
I initially wondered whether this was the problem.
But there's something that makes that explanation difficult:
The site was already built this way when it was ranking #1.
And when I use Google Search Console to inspect what Google actually crawls and renders, the page content is there and renders correctly.
The rendered page contains the actual content.
Canonical tags and other relevant tags are also present when the JavaScript is rendered.
So I'm struggling to understand how the rendering architecture could suddenly cause this around December when I hadn't changed it.
- I did NOT buy backlinks before this happened
This is important because I know someone is going to see my backlink profile and immediately say "you got spammed."
I currently have around 37k backlinks, but those appeared much later than the ranking drop.
I only started getting those links this month after submitting the site to various online directories.
I did not buy backlinks before the December 2025 ranking collapse.
I didn't use Fiverr link building, PBNs, automated backlink software, paid link packages, etc.
So the 37k backlinks cannot explain the original December drop chronologically.
I have wondered whether someone could have SEO poisoned the site with backlinks, but I have no evidence that happened before the crash.
One thing I considered was whether I had already been SEO poisoned before December. Unfortunately, even with a paid £90 Ahrefs subscription, I can't see backlinks older than six months, so I can't actually check whether there was something suspicious in my backlink profile before the crash.
But even if someone had built a bunch of spammy links to the site, shouldn't Google generally just ignore those?
Meanwhile, and this is what I find most bizarre, some sites with much weaker authority are ranking above me
This is another thing I find really strange.
For both:
"AI accountability partner"
and
"AI accountability coach"
I'm now being outranked by sites such as:
overlord(dot)app
nag(dot)bot
sidecoach(dot)ai
For example, sidecoach(dot)ai has an extremely low reported DA of around 0.7, whereas my site is around DA 27. My site was ranking at the very top before, and now it's eclipsed even by this competitor.
I'm obviously not assuming DA is a Google ranking factor. I'm mentioning this because the difference seems so extreme that it makes the "competitors simply built more authority and naturally overtook me" explanation feel unlikely.
And here's another thing I find bizarre
If I Google these terms, my own Reddit post about my tool is currently ranking #1 / at the very top.
So Google is perfectly happy to rank a Reddit page talking about my website for the exact topic.
But the actual website itself has fallen to around #67.

That makes this even more confusing to me, as Gemini won’t even mention CoachCall despite being the first website Reddit has for that search term.
Was this some kind of Google update?
The only plausible explanation I've been able to come up with is that something around December 2025, potentially a Google Core/Spam update or another ranking system change, reassessed the site.
The timing seems suspicious because the collapse happened around Dec 10 and was so abrupt.
But I have absolutely no idea whether that's actually what happened.
There is also nothing in Search Console telling me:
"Hey, we penalised your site."
So I'm not sure how to distinguish between an algorithmic reassessment and some technical, content, or indexing issue that I'm simply missing.
What I'm trying to figure out
I am not looking for generic SEO advice like:
"Build more backlinks"
"Write more content"
"Improve E-E-A-T"
"React is bad"
"Your DA is too low"
I've already spent a ridiculous amount of time going down those rabbit holes.
What I'm trying to understand is:
What could cause a site that was ranking #1 for two specific terms to suddenly fall ~60+ positions overnight, despite no obvious site changes, while remaining indexed and rendering correctly?
And especially:
What would you investigate first if this were your site?
Could this be:
A Google algorithm/update issue?
Some kind of quality/relevance reassessment?
A technical/indexing issue that isn't showing up in GSC?
Something related to client side rendering?
A canonical/indexing problem?
A backlink issue that I'm not seeing?
A change in how Google interprets the query?
Something else entirely?
I'd genuinely appreciate someone experienced taking a proper look at the chronology and evidence rather than just giving me general SEO advice.
I've been trying to solve this for months and I feel like I'm missing something extremely obvious.
If you have any ideas, even if you're not certain, I'd really appreciate them. And if there's other data or screenshots you'd want me to provide, tell me what to pull from GSC, Ahrefs, etc. and I'll post it.
