How long does it take for a BIMI logo to update in Yahoo cache and how to fix SVG logo errors?

Summary

Updating a BIMI logo in Yahoo's cache can be a lengthy process, often taking days or even weeks, due to caching and validation processes. The most critical aspect is ensuring a correctly formatted SVG logo, which must be a perfect square, use a secure HTTPS URL, and crucially, have the `<title>` element placed as the first child of the `<svg>` element, outside of any `<g>` tags. Validation using an SVG validator is highly recommended. Additionally, ensure correct DNS records, a valid VMC (if required by Verizon Media/Yahoo/AOL), and if problems persist, contact Yahoo support directly due to potential issues on their end. Propagation times vary across ISPs; monitor your BIMI record and be patient.

Key findings

  • Yahoo Caching Delays: Yahoo's BIMI logo updates are often delayed due to caching mechanisms. Expect potential delays of days or weeks.
  • SVG Formatting Crucial: Correct SVG formatting is paramount. This includes a perfect square aspect ratio, secure HTTPS URL, and correct `<title>` element placement.
  • Title Element Placement Key: The `<title>` element must be the first child of the `<svg>` element and outside any `<g>` grouping tags.
  • Verizon Media VMC Requirement: Verizon Media (Yahoo, AOL) requires a valid VMC for BIMI implementation.
  • Validator Recommended: Using an SVG validator is highly recommended to catch subtle errors in the SVG code.

Key considerations

  • SVG Verification: Thoroughly verify the SVG is a perfect square, uses HTTPS, and has the `<title>` element correctly placed.
  • DNS Record Checks: Double-check all DNS records for accuracy and correct VMC association (if applicable).
  • Verizon Media Compliance: If targeting Verizon Media (Yahoo, AOL), ensure compliance with their specific requirements, including the VMC.
  • Patience & Monitoring: Be patient as propagation times vary. Monitor the BIMI record and allow ample time for updates.
  • Contact Support if Needed: If issues persist despite all checks, contact Yahoo support for assistance.
