Definition
Duplicate content is text that is identical or very similar across several web pages, on the same site or on different sites, which Google treats as a problem because it dilutes the relevance of search results and blurs which page is the reference. Google then has to guess which version deserves to rank.
In plain English
When Google detects duplicate content, it has to choose which version to index and show in its results. That creates confusion: the search engine does not know which page to favor, which weakens the ranking of every version involved.
Duplicate content can be internal (several pages on the same site carry the same text) or external (your content is copied elsewhere, or the other way around). Either way, you risk diluting your visibility: instead of one strong page in position 1, several weak pages compete for positions 8 to 15.
Accidental duplication is common on law firm websites: near-identical practice area descriptions, automatically generated content, printer-friendly versions of pages. Google does not always penalize it, but you lose the chance to make each page count with unique content that answers one specific search intent.
For a law firm
An employment law firm creates four separate pages for "wrongful termination lawyer Dallas," "wrongful termination lawyer Houston," "wrongful termination lawyer Austin," and "wrongful termination lawyer San Antonio." The writer copies the same 800-word text onto each one and changes only the city name.
The result: none of these pages ranks well. Google hesitates between the four versions, indexes them at random, and ends up favoring competitors that wrote original content for "wrongful termination lawyer Dallas." The fix is to build one main reference page, then truly differentiate each local page with regional context: local court decisions, regional labor data, and the specifics of the local job market.
The same problem comes up with partner bios copied onto several legal directories, such as Avvo, Justia, and FindLaw, or with legal news reposted word for word from a government website.
The Hendy figure
In the SEO audits we run for law firms, we find that 18% of pages on average are internal duplicate content, mostly practice area descriptions copied across cities or client types (individuals and businesses).
In other words, nearly one page in five on a typical law firm site competes with another page of the same site instead of supporting it.
Key takeaways
- Duplicate content dilutes your authority on a topic instead of concentrating it on one reference page.
- Internal duplication is more common than external copying, and a structured editorial plan fixes it.
- Each page should answer a distinct search intent with genuinely different content, not cosmetic variations.
