Proxy
A proxy server is an intermediary server that sits between a client device and the internet, forwarding requests on behalf of the client. In SEO, proxies are used for rank checking at scale (to avoid rate limiting by Google), competitive research, and scraping. Reverse proxies on the server side are used to cache content and improve performance.
From an SEO tooling perspective, rank tracking tools like SEMrush, Ahrefs, and Rank Tracker use distributed proxy networks to check rankings from different geographic locations and devices. Server-side reverse proxies (Varnish, Nginx, Cloudflare) are configured by DevOps teams and audited via server log files for caching efficiency.
