  • DC issues - Diagnosis & causes
  • For example, a blog entry may appear on the home page of a blog, in an archive page, and in a page of other entries with the same label.
  • Not forgettingprintfriendlypages,tracking and sortingURL parameters, www and not www etc…https://www.google.com/webmasters/tools/spamreport?hl=en&pli=1
  • Google does not recommend blocking crawler access to duplicate content on your website, whether with a robots.txt file or other methods. If search engines can't crawl pages with duplicate content, they can't automatically detect that these URLs point to the same content and will therefore effectively have to treat them as separate, unique pages. A better solution is to allow search engines to crawl these URLs, but mark them as duplicates by using the rel="canonical" link element, the URL parameter handling tool, or 301 redirects. In cases where duplicate content leads to us crawling too much of your website, you can also adjust the crawl rate setting in Webmaster Tools."Boiler plate" originally referred to the maker's label used to identify the builder of steam boilers. This link shows an example of a boiler plate.In the field of printing, the term dates back to the early 1900s. From the 1890s onwards, printing plates of text for widespread reproduction such as advertisements or syndicated columns were cast or stamped in steel (instead of the much softer and less durable lead alloys used otherwise) ready for the printing press and distributed to newspapers around the United States. They came to be known as 'boilerplates'. Until the 1950s, thousands of newspapers received and used this kind of boilerplate from the nation's largest supplier, the Western Newspaper Union.[citation needed]Some companies also sent out press releases as boilerplate so that they had to be printed as written. The modern equivalent is the press release boilerplate, or "boiler," a paragraph or two that describes the company and its products.
