Instart Logic is a content delivery network CDN, which claims to have a positive effect on time to first bite (TTFB). Faster site = good for SEO, right?
Our initial investigation seems to confirm its claims to some degree, which is great, but at the same time we think it may lower our score on Google's PageSpeed Insights tool, which sort of negates its effect in other areas. If the user experience is worse (according to Google's own tool), are we effectively shooting ourselves in the foot by concentrating on TTFB as a ranking algorithm factor?
