Green: vk.ru. Thin bar: Social Media & Networking peer median.

Priority fixes for vk.ru

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for 4 days, short of the 30-day benchmark.

   Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.

   What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.

   55% of Social Media & Networking peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Harden

   HSTS kept for at least a year

   Observed: Strict-Transport-Security was sent with a max-age of 183 days, below the one-year benchmark.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

   38% of Social Media & Networking peers do this.

3. Priority 3 · Enable

   XML sitemap discoverable

   Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.

   What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.

   64% of Social Media & Networking peers do this.

4. Priority 4 · Enable

   Meta description written

   Observed: The homepage had no meta description.

   What to do: Write a short, specific description of the page for people, not a list of keywords.

   93% of Social Media & Networking peers do this.
