Yesterday I wrapped up my very first talk at BrightonSEO 2025. It was warm enough that I delivered it in a t-shirt and shorts. In April. In England. The weather felt more like July, and so did the energy.
My talk was titled “Unlocking SEO Wins with Cloudflare Workers: No Devs Required.” The idea came from a reality most technical SEOs deal with constantly: you know what needs to be done, but you’re blocked by dev resource. They’re not unhelpful, they’re just fully booked. SEO tickets drop to the bottom.
This talk showed how Cloudflare Workers let us bypass that. Not recklessly, not permanently. But tactically, and quickly. It was about proving what we can do with the access we already have.
Override Canonicals
When a CMS or template is outputting the wrong canonical, you can rewrite it at the edge. I showed how to detect and correct bad canonicals using Workers with scoped routing.
Inject Schema Markup
Need to add structured data to a page but don’t have code access? Workers let you inject JSON-LD into the head without touching the CMS.
Cache Third-Party Scripts
One of the best received demos. We intercepted a slow script from a third-party domain and cached it locally using a Worker. Load time dropped by 63 percent. That’s real Core Web Vitals improvement with no code changes.
Generate Meta Descriptions
For pages missing meta descriptions, we built a Worker that extracts the first paragraph, trims it to 160 characters, and injects it into the head.
Preserve Crawl Budget
We updated robots.txt and served 410s for legacy URLs that no longer need to be indexed. All at the edge. All without dev involvement.
This wasn’t a talk about theory. These are things I’ve deployed for clients. In every case, we were waiting on devs. In every case, we shipped faster because we didn’t.

Thanks to everyone who came, asked questions, or followed up. And thanks to the BrightonSEO crew for another sharp, focused event.
