Just recorded my first podcast 🎙️

I joined the Niche Pursuits Podcast to talk about bootstrapping 3 SEO SaaS, what worked (and didn’t), and where SEO might be heading.

Fun experience, thanks @JaredBauman

Toujours intéressant de confronter la théorie SEO aux données terrain.

[François Mommens @mommens]

The thing with serial entrepreneurs shipping product after product is that they already have an audience, usually earned from a first win.
That makes validation fast.
For the rest of us, every product starts with a promotion grind.

Merci à @jsellitto pour la mise en avant d’Indexometer sur @abondance_com. En espérant que ces données aident la communauté SEO à mieux comprendre comment Google indexe le web. #seo

En novembre 2025, Google n’a indexé que 70 % des 250 000 pages testées avec Indexometer de @IndexCheckr

➡️ 3 pages sur 10 restent donc hors de Google, même présentes dans les sitemaps.

🚀 Introducing the Indexometer

Each month, we measure how much of the web Google actually indexes.

📊 First results:
October 2025: 72.9%
November 2025: 70.0%

Sample: 250,000 URLs across 20,000 domains.

See the full chart + methodology ↓

[François Mommens @mommens]

Google indexed 3.98% fewer pages in November.

📊 October: 72.9% indexed
📉 November: 70.0% indexed

Each month, the Indexometer checks 250 000 URLs from 20 000 domains to track Google’s real indexing rate.

Why do you think indexing is slowing down?

Is not having competitors a good or a bad thing?

Painful lessons, but I’m still building.

Nobody talks about failure.
I spent $136k and 4 years to reach $2.5k MRR.
Here are a few mistakes I made:

[François Mommens @mommens]

And maybe the biggest one:
I fell into the sunk cost fallacy. I kept going because I’d already invested too much to stop.
