On-Page SEO
Duplicate title
A duplicate title occurs when two or more distinct URLs render the same or functionally indistinguishable HTML document title.
What it means
Duplication often comes from missing template variables, paginated views, product variants or boilerplate that omits the unique subject. The URLs may contain different content, so the title defect must be diagnosed separately from canonical duplication.
Why it matters
Identical titles make browser tabs, reports and search results harder to distinguish and give search systems weak document-identification signals. The correct fix depends on whether the URLs are unique, alternate or accidental duplicates.
Example
Every course page renders `Online Course | Academy` because the course name variable is empty. The template is corrected to include the verified course name while canonical relationships remain unchanged.
Common mistakes
Do not redirect URLs solely because titles match, add arbitrary keywords to make strings unique or ignore faceted and paginated templates. Determine whether the underlying pages deserve separate Indexing first.
