Duplicate title tags: fix the title generator

How to fix duplicate title tags

First group the affected URLs by their final canonical document and compare the content. Two distinct pages can share a title because a template falls back to the same text. That is a title-generation defect, not a reason to canonicalize one page to the other.

Give each page a concise title describing its subject and intent, with branding kept brief. Check the initial response and rendered head for a single title element, then confirm that the visible main heading describes the same page.

If the URLs really are duplicate versions of one document, consolidate their URL signals instead. Keep maintained destinations in the sitemap and point internal links directly to them. Google can generate a different search-result title; changing the HTML does not establish a ranking change.

Google’s title-link guidance explains distinct, descriptive titles; its canonical URL guidance covers duplicate representations.

The emitted titles expose the collision

The collision begins in the shared service template. A fallback title can conceal different substantive pages even when both canonical URLs are correct.

I would request both pages directly and navigate between them after deployment, because a page can arrive at the right URL while the old title survives in the rendered head even when its own initial response supplies the correct title. A test that checks only the destination URL would miss the template collision.
