  • Response compression enabledlow impactlow effort

    no content-encoding header

    This HTML is served uncompressed, so every visitor downloads far more bytes than necessary — text compresses extremely well, and the savings directly speed up first render on slow connections. Enable Brotli or gzip on your server or CDN: in nginx it's "gzip on;" (or the brotli module), in Apache it's mod_deflate via .htaccess, and on most CDNs it's a single toggle. Make sure compression covers all text types (HTML, CSS, JS, JSON, SVG), but skip already-compressed images — recompressing them wastes CPU for no gain.

  • Reasonable HTML sizelow impactmedium effort

    1.1 MB

    A very large HTML document slows parsing on every visit and risks exceeding the portion of a file crawlers are willing to fetch — content past the cutoff may simply never be indexed. Slim it down: move large inline <script> and <style> blocks into external cacheable files, strip embedded JSON data blobs and base64-encoded images, and paginate or lazy-load very long listings. Check the most common culprit first: a framework serializing the entire page state or dataset into the document itself.
