  • Canonical Formats and Query Strings

    www.mysite.com/mypage.aspx and www.mysite.com/mypage.aspx?param=1 are reported with the SEO violation "The page contains multiple canonical formats". Does this imply that in general query strings are bad news SEO wise? As an extreme example, I have a property booking site where the query string contains the parameters "propertynumber" and "bookingdate" leading to a large number of reported violations. I could of course recode to pass the information in another fashion.

    The short answer is that it does not necesarilly means Query Strings bad for SEO, but it might. It really depends on your content. I would need to understand more on how your page changes based on this query string and if in fact you want those pages to be indexed as different pages in search engines. In the meantime I wrote the long answer here:

    Thanks for that! I had spent some time "Binging" around the topic but your blog entry is a model of clarity. I take to heart your suggestion to take charge of the canonical relationships and not leave it to the search engines to second guess my intentions. Fortunately in my case, it is a simple matter to remove the query string altogether.
