Long Articles – Another Canonical Tag Use

The canonical tag has a lot of applications, and one of them is helping to simplify duplicate content issues. One of these situations frequently occurs with long pieces of content which have been broken out over several pages to improve usability. This is common for content publishers such as newpapers, but also happens with other types of sites. It’s common to use pagination links such as these ones (from Lester Chan’s WP-Pagenavi plugin) to help users and engines find the rest of your article. 

One great B2B content development strategy can be publishing transcripts of webinars, podcasts or conference calls. These transcripts can easily run into thousands of words, and pagination can be a good choice for readability, however it quickly becomes a duplicate content issue. One client recently had a webinar transcribed which ran into 14 pages. To start with, that potentially creates 14 sets of Meta Data to be written, and 14 different places where people could link. While the content is broken into pages around the themes within the webinar, it’s all around a topic which is quite niche to begin with.

This is a classic case where existing best practices would have tried to focus the authority on the first page, and attempted to reduce the duplicate potential of the other pages by using a combination of links, 301 redirects and the Robots Exclusion Protocol. Now we can use a much more straightforward solution in the canonical link tag.

In the example I mentioned before, you would implement the tag across all 14 pages. The tag has the effect of telling the search engines "this is the preferred version, and the one we like the most". It also transfers signals like PageRank to the canonical (preferred) URL. The tag would look like this:

 <link rel="canonical" href="http://www.example.com/first-page.html" />

This will help focus link juice and authority, as well as help deal with possible duplicate content issues.
