Publishers are often concerned about the impact third party tags have on performance. Fortunately, the Quantcast asynchronous tag has minimal impact on load time because it enables your web page content to load first. To learn the technical details of how we’ve accomplished this, please see our Web Measurement Implementation Guide.
Making a site fast certainly has it’s advantages, but it does not significantly improve your chances of reaching top positions in search results (see related article). According to Google’s Matt Cutts “we still put much more weight on factors like relevance, topicality, reputation, value-add, etc. — all the factors that you probably think about all the time. Compared to those signals, site speed will carry much less weight.”
Last year, on the Webmaster Central Blog, Google stated “While site speed is a new signal, it doesn’t carry as much weight as the relevance of a page. Currently, fewer than 1% of search queries are affected by the site speed signal in our implementation”.
100+ million web destinations across the web directly measure their properties via the Quantcast tag. This speaks to the confidence that many publishers place in its performance. View a list of many of our Quantified publishers.
