Performance is one of our top priorities that we try to balance with the rich set of features that have been requested. Keep in mind that performance tools, such as Google Page Speed, show the cold cache and no cookie experience that few users will have due to our reach. We’d love to work with you to find out how or why our tools have impacted your site. Please reach out to us at help@addthis.com and we’d be happy to assist you.
About the price – our tools have always been available for free with no usage limits. We do offer modest paid plans with additional features, such as reduced branding and other customization options.
As part of our dedication to site performance we are having a webinar on “Tips for Making Your Website Load Faster” with a speaker from iStrategyLabs. Check it out and register here.
