Edge SEO is the practice of utilising functions and “service workers” running on major content delivery networks to further optimise the technical setup of a site at page-level.

Edge SEO is an important tool for companies of all sizes where development queues are long, or platform development isn’t possible. By altering content on the CDN nodes (“the network edge”), it is not necessary to have server, platform or CMS-level access. All the changes are made after the HTML leaves the server.

Additionally, by using cache logic, we can help you implement 301 redirects and upgrade 3xx temporary redirects to permanent ones. By using a CDN you can also gain visibility of your access logs if this isn’t possible through your existing platform (i.e. Shopify) or IT team.

A/B testing SEO changes on a CDN

Although this practice isn’t “new”, it’s a fairly recent addition to most SEOs’ technical arsenal. If you have a large, high traffic and templated website then our team can suggest appropriate A/B tests whereby certain subsets of your pages can be altered and the uplift in search visibility and traffic measured. Contact us to discuss if this option is right for you.
