Hi folks,

There is a popular myth about duplicate content, and that is that Google penalizes sites for having duplicate content.

Greg Grothaus of the Search Quality Team of Google cleard that Google itself is not penalizing you for it.

Google recognizes that most duplicate content is not created to be deceptive. There are of course exceptions, which are considered spam. They're being penalized for being spam but not for having duplicate content.

There are some issues that can arise that may negatively affect your rankings.

1) Your link popularity will be diluted. Backlinks pointing to several different URL versions(like domain.com, www.domain.com, domain.com/index.htm) of the same content, will make it harder to accumulate link juice for one URL.

2) User-unfriendly URLs in search results may offset branding efforts and decrease usability as well.

3) With multiple versions of the same thing, Google will spend more time crawling the same content, meaning it will have less time to go deeper into your site, and you run the risk of having content not get indexed.

Quick clarification tying the thread together: is right that Google doesn’t automatically “penalize” innocuous duplicate content — manual action only comes into play when duplication is clearly deceptive, spammy, or part of an abuse pattern. Search systems try to pick one URL to show and consolidate signals; your job is to make that preference obvious. (developers.google.com)

Concrete, prioritized fixes (internal duplicates and URL variants):

  • Prefer server-side 3xx redirects when you want to retire a URL (strongest signal).
  • Use a single canonical URL for each piece of content via a rel="canonical" link in the page head (or Link HTTP header for non-HTML files).
  • Make your sitemap list only the canonical URLs and keep internal links pointing to those canonicals.
  • Avoid trying to “canonicalize” by blocking the canonical page with robots.txt or by mixing noindex with canonical — that breaks the signal.
    Example canonical and redirect patterns:

<link rel="canonical" href="" />

Apache example:
Redirect 301 /old-page

These methods are the recommended workflow for consolidating duplicates and preserving link value. (developers.google.com)

Syndication, edited reposts and scrapers: crediting the source (as suggested) is important editorially, but by itself it won’t guarantee search visibility. If you syndicate, ask partners to either (a) add a rel="canonical" to your original, (b) include a clear link attribution and publish your version first, or (c) apply a noindex on the copy if appropriate. If content is clearly scraped and harming your site, monitor the Manual Actions/Spam reports and use URL inspection, sitemaps and removal/DMCA options as needed. (developers.google.com)

Short checklist to take away: pick one canonical URL, enforce it with redirects or rel=canonical, keep sitemaps and internal links consistent, and monitor Search Console for crawl, index, and spam/manual-action signals.

Also, sam09 is talking about the same content under multiple URLs on the same page. Duplicate content is usually revolving around the same article or content across multiple websites (aka plagiarism).

Will Google even track the contents that are duplicate but edited in the way that they will not be recognized by bots and if someone posts the content but gives credits to original content, will Google still penalize the website?

The appropriate way to reproduce content is to use the <blockquote> html tag, and use <blockquote cite="original source url"> to give credit. This tells Google that your content is reproduced and so if someone does a Google search, show the original content and not yours (so you won't really get any Google traffic off of a page with a reproduced article) but you don't get any type of penalty for duplicate content yourself either. And that's a good thing.

Sorry, So my post can be considered as duplicate content. :)

Appropriately enough, DaniWeb uses <blockquote cite=""> for all

bbcode, where the cite URL is the permalink to the individual post you cited.
