How to Get Maximum SEO Impact from the IngenCO2 Certificates

Google is into link-authority again — not just little drips, but the full arsenal. That means older link-building strategies matter again. A certification scheme I liked before is now a strong addition to your link profile — and you boost your CSR profile at the same time.

It only costs 1,940 DKK to neutralize your website. You must link to your certificate, so there's a bit of mutual linking involved (you can do that from a no-indexed CSR page). And yes — it's not as good as a one-way link, obviously. But you also get links from an additional 4 other sites, which you're not linking to. So in total you get 5 links. And the sites have serious authority:

co2neutralwebsite.com – Ahrefs DA 79, Majestic TF 42, CF 59
co2neutralwebsite.de – Ahrefs DA 76, Majestic TF 46, CF 54
co2neutralwebsite.fi – Ahrefs DA 43, Majestic TF 32, CF 50
minskaco2.se – Ahrefs DA 65, Majestic TF 33, CF 51
ingenco2.dk – Ahrefs DA 79, Majestic TF 45, CF 52

You also get a link from the participant list on the various sites — but those links are JS-links, and there are many participants on each list. That means the authority gets divided between all members on a single page, which hardly leaves much for your site. But each site also issues an individual certificate page. And each of these pages links directly to you. No redirects. No shared link juice. Pure, do-follow link to your site.

Why It Works — Both for SEO and CSR

Here's why IngenCO2 certificates are a smart activation in 2025:

✓You get five strong links from five separate domains.
✓They come from domains with high trust and proven authority.
✓You improve your site's trust and E-E-A-T at the same time.
✓And you stand stronger both with users and the press (CSR).

It's one of the few SEO opportunities where you get branding, trust and high link value — at a price where you'd normally only get one guest-post on a DA-40 site. Sure, "E-mærket" and other label schemes have their place — but there you only get a single link, and at a markedly higher price.

How to Get the Most out of IngenCO2

All of IngenCO2's platforms are built the same. Same structure, same sitemap setup, which is where the links to the certificates come from. But all certificate pages are orphan pages. They're not linked internally from navigation or menus. In other words: Google can find them — but they only become strong when you help them.

How to Breathe Life into the Certificates

These certificates, as said, don't function optimally by themselves. They must be activated and then boosted. Here's the step-by-step:

1. Find your five certificate URLs

They follow the same format with ID and language variant. Here are mine for reference:

https://www.co2neutralwebsite.de/certificate/7738/de
https://www.minskaco2.se/certificate/7738/se
https://www.co2neutralwebsite.fi/certificate/7738/fi
https://www.ingenco2.dk/certificate/7738/da

2. Send them for indexing

Use IndexInject or another ping system. It kicks Google into gear, so you don't wait for impact you could have now.

3. Link to them yourself

You need to link to the one certificate yourself, so it gets indexed fast. You can also choose to link to the other certificates to enhance their value, which then flows to you. Instead of linking from your main website, you could do it from a guest-blog post, press release or something else entirely.

4. Boost them with 2-3 tier-2 links each

Small, easy links from niche blogs, partner sites or niche forums. Could also be from PBNs. You just need to elevate the authority of the individual certificate page.

And What Do You Get Out of It?

Links from sources with authority around 60 — some nearing 80 — are rare. If you don't have many strong link sources, they can change the game for your site's visibility. Here you get five links with serious authority, one from each domain.

Quick Summary of IngenCO2 as a Strategy:

📉Certificate without links? Weak effect.
📊Certificate pinged and indexed? OK effect.
📈Certificate boosted with tier-2 links? Strong effect.

Why It Works in 2025

Google still looks at relevance. But authority is back in the driver's seat. And with five links from domains with DA65+, you transfer a lot of authority to your own site. And as a bonus? You're doing something good for the planet. IngenCO2 is a real certification scheme — the purpose is actually to neutralize the CO2 a website emits. The purpose isn't link-building. But you can definitely use it for link-building.
