A small web agency was looking for ways to add value without constantly chasing bigger projects. They already offered design, maintenance, SEO, and performance optimization. The problem was that every proposal looked almost identical to what dozens of other agencies were putting in front of the same clients.
Then a client asked about the environmental impact of their website.
It was a small question — almost offhand. But the agency had no answer. No data, no benchmark, nothing to point to. The conversation moved on, but the gap stayed with them.
The Add-On
Instead of building a new service from scratch, they added a website sustainability report to their existing maintenance package. The report showed how much data the site transferred per visit, estimated CO₂ emissions per page view, and tracked whether things were improving or getting worse over time.
The first client they showed it to loved it. Not because they had suddenly become obsessed with carbon emissions — but because it gave them a clear, visual metric they could share with their own management and include in internal sustainability initiatives. Something concrete where before there was nothing.
The agency started offering monthly sustainability monitoring as a standalone add-on for $200 per client per month.
The Math
Monthly monitoring tool
$299/month for up to 100 client sites
Add-on price per client
$200/month
Break-even point
2 clients paying for the add-on
With 10 clients
$2,000/month in new recurring revenue
The service required almost no extra effort. Most of the work was already happening through regular maintenance and optimization. The reports simply gave clients a new way to see the value of work that was already being done.
What Happened Next
A few clients signed up. Then more.
What started as a response to one client question became a reliable source of recurring revenue — billed monthly, low overhead, easy to explain.
But the biggest surprise wasn't the extra income.
It was how often the reports opened new conversations. Instead of discussing only website bugs and content updates, the agency was talking about measurable improvements, sustainability goals, and long-term website performance. Clients started bringing them into broader strategic discussions they hadn't been part of before.
The websites were already being maintained. Now there was a better way to show the results — and a reason for the client relationship to keep growing.
How to Replicate This
The approach doesn't require a new service line, new expertise, or new staff. It requires three things:
A way to scan and track client sites
You need CO₂ per page view, an A–D rating, and trend data over time. That's what MyCarbonScan provides — daily automated scans for every site in your account.
A client-ready report
The report has to look professional enough to hand to a client or drop into a quarterly review deck. It needs to be generated automatically, not assembled manually.
A simple pitch
"We now include monthly sustainability monitoring as part of our service. You get a carbon score for your site, tracked over time, that you can share with your own stakeholders." That's it. Most clients say yes.
