PHPKB is not just a great knowledge base tool, it also offers solid SEO support for your knowledge base pages so search crawlers do not report issues like duplicate pages, duplicate titles, and missing canonical tags.

What is a canonical tag?

A canonical tag is a way of telling search engines that a specific URL represents the master copy of a page. Using the canonical tag prevents problems caused by identical content appearing on multiple URLs. Practically, the canonical tag tells search engines which version of a URL you want to appear in search results.

Why does canonicalization matter?

Duplicate content is a complicated subject, but when search engines crawl many URLs with identical or very similar content, it can cause several SEO problems such as:

  • If search engines have to go through too much duplicate content, they may miss some of your unique content.
  • Large-scale duplication may affect your ranking ability. Canonicalization helps you control your duplicate content.
  • Even if your content does rank, search engines may pick the wrong URL as the original. The canonical tag tells search engines which version of the URL you want to appear in search results.

Canonicalization in PHPKB Knowledge Base Software

If an article is posted in multiple categories, the same article appears multiple times with different URLs based on category. In such a case, a search engine might consider them as duplicate contents and impose a penalty on the knowledge base. By adding canonicalizations, PHPKB knowledge base software guides the search engine about which page to index i.e. which is the original page.

<link rel="canonical" href="https://www.yoursite.com/kb/category/article-title-here.html" />
