What is Duplicate Content?
Substantively identical content at multiple URLs, from facets, parameters, or syndication. Diagnose the pattern (template, locale, pagination) before prescribing canonicals or consolidation.

Canonical Tag
A hint (rel="canonical") naming the preferred URL when duplicates exist. Only about three in five pages web-wide carry a valid one, so validation must cover target quality and conflicting signals.
Duplicate Title Tag
Identical titles across pages, usually a symptom of faceted URLs or weak templates rather than the root problem. Fix the URL pattern or template, not just the string.
Content Consolidation
Merging overlapping pages into one authoritative URL with 301s and link updates. Consolidation resolves cannibalization and gives one page the combined relevance and links.
On-Page SEO
Optimizing individual pages: titles, headings, content depth, internal links, images, and schema. On-page work decides relevance once technical SEO has made the page reachable.
Title Tag
The clickable headline in search results and the strongest on-page relevance signal. Google rewrites most titles, so clarity and completeness beat rigid length rules.
Meta Description
The optional summary that can become the result snippet. Absence is not a penalty and Google rewrites most descriptions, so prioritize valuable pages where controlled wording earns clicks.
