A few weeks ago I noticed on my AdSense Home page that Google were showing a ranking for Revenue Optimisation, site health and Google +. Under site health it said that I had a page speed performance issue with my most popular page.
Following this through I've taken what advice I can implement with my limited knowledge of HTML. I've resized all images, and made Facebook/Twitter load asynchronously (if that's a word!).
I'm now getting a score of 94 out of 100 (sometimes 97, presumably depending on demand on the server), but I've no way of knowing whether that's good or not.
So can I now relax and get on with writing content, or is 94 - 97 still a slow speed?
