Until now, chartbeat has limited how many sites you can track to five. However, you’ve been asking for the ability to track even more sites and now you can! If you try to add a sixth site to your chartbeat account, you’ll automatically be taken to an upgrade page where you can add more sites to your account in batches of five. Alternatively you can simply go to http://chartbeat.com/plans and pick the number of sites you want to track there. As a guide, the pricing for each set of five sites rises in increments of $9.95. After selecting the plan you want, click change and hey presto you’ll be able to add more sites. One caveat: early users who signed up with Paypal will have to switch to a more standard payment method to add more domains, because of restrictions in the way Paypal handles charges. Please contact firstname.lastname@example.org if you have any issues. New plans for very high traffic sites We've also previously been limiting the number of concurrent visitors measured on each site to 5,000 at any one time. This safely covers all but the biggest sites on the web. However, a few companies with massive audiences have been asking us for a higher limit, so over the last few weeks we've been testing higher limits and the system has been responding just fine. As a result, if you are hitting the 5,000 simultaneous visitor cap please do email us at email@example.com and we can move you onto a tailored plan for your size.
