🎨 Setting Up a Consistent Look and Feel Across All Blogs

Search Atlas does not currently have a single built-in "global blog template" feature that automatically applies one design to every blog. However, you can achieve a consistent look and feel across all your blogs using the workarounds below.

📋 Option 1: Use Brand Vault as Your Style Reference

Brand Vault stores your brand assets — logos, color palettes, and font choices — so you can apply them consistently when building or editing each blog.

  1. Access Brand Vault: top-right More Features menu (grid icon, next to your account menu) → Brand Vault, or Header More Features menu (apps-grid icon, top-right) → Brand Vault.
  2. Confirm your brand colors, fonts, and logo are saved.
  3. When creating or editing a blog in Website Studio, open the Brand Vault panel and apply your saved brand assets to match your desired style.
  4. Repeat this process for each blog to keep styling consistent.

Limitation: Brand Vault does not push styles automatically. You must apply your brand assets manually to each individual blog.

🖌️ Option 2: Apply Custom CSS to Each Blog

If you need more precise control over the visual appearance, you can add custom CSS directly to each blog.

  1. Open the blog you want to style in Website Studio.
  2. Go to Settings within the blog editor.
  3. Locate the Custom CSS field.
  4. Paste your CSS rules. Use the same CSS code for every blog to keep the look consistent.
  5. Save and preview to confirm the styles are applied correctly.

Tip: Keep a copy of your CSS snippet in a text file so you can paste it quickly into each blog without re-writing it.

📄 Option 3: Duplicate an Existing Blog as a Starting Point

  1. Build and style one blog to your exact specifications.
  2. Use the Duplicate option on that blog to create a copy.
  3. Rename the duplicate and update its content.
  4. Repeat for each additional blog you need.

This is the fastest way to maintain a uniform design when creating multiple new blogs from scratch.

🔍 Understanding the "11 Pages Have Multiple Canonical URLs" Error

A canonical URL tells search engines which version of a page is the primary one. When Search Atlas detects that 11 pages each have more than one canonical URL defined, it flags this as an error because conflicting canonical signals can confuse search engines and hurt your rankings.

⚠️ Common Causes of Multiple Canonical URL Errors

  • Duplicate canonical tags in the page source: A canonical tag exists in both the <head> section and an HTTP response header, creating two competing signals.
  • Pagination misconfiguration: Paginated content (page 2, page 3, etc.) is accidentally self-canonicalizing each paginated URL instead of pointing back to the root page.
  • Sitemap conflicts: Pages listed in the sitemap have a canonical tag pointing to a different URL, creating a mismatch.
  • Blog post syndication or duplication: The same content exists at multiple URLs with inconsistent or missing canonical tags.
  • Plugin or theme conflicts (external sites): If your site is connected to Search Atlas via integration, an external plugin may be injecting additional canonical tags.

🛠️ Step-by-Step: Diagnosing the Error

  1. Go to OTTO SEO → Site Audit in the left sidebar of Search Atlas.
  2. Open the latest crawl report and filter for Canonical issues.
  3. Click into the Multiple Canonical URLs error to see the full list of affected pages.
  4. For each affected page, note the conflicting canonical URLs shown in the report.
  5. Open your browser and view the page source (Ctrl+U or Cmd+U) to find all <link rel="canonical"> tags in the <head> section.
  6. Also check the HTTP headers of the page using a tool such as a browser extension or developer tools to detect header-level canonical tags.

✅ Step-by-Step: Fixing the Error

  1. Remove duplicate canonical tags: Ensure only one canonical tag exists per page, placed in the HTML <head>. Delete any additional or conflicting tags.
  2. Fix pagination settings: Paginated pages should either self-canonicalize correctly or use rel="next" and rel="prev" markup. Do not have page 2 canonicalize to page 1 unless that is intentional.
  3. Align your sitemap: Make sure every URL in your sitemap matches the canonical URL defined on that page. Remove any URLs from the sitemap that are not the canonical version.
  4. Check for HTTP header conflicts: If your server or a caching plugin is adding a Link: <URL>; rel="canonical" header, disable that setting to avoid conflicting with your HTML canonical tag.
  5. Re-crawl your site: After making changes, return to OTTO SEO → Site Audit and trigger a new crawl to confirm the errors are resolved.

🔄 Verifying the Fix

Once the re-crawl is complete, return to the Canonical issues section of the Site Audit report (OTTO SEO → Site Audit). The 11 affected pages should no longer appear under Multiple Canonical URLs. If any pages remain flagged, repeat the diagnostic steps for those specific URLs.
