Title: Leverage browser caching – Super Cache Last modified: September 15, 2016 --- # Leverage browser caching – Super Cache * [hadders](https://wordpress.org/support/users/hadders/) * (@hadders) * [9 years, 8 months ago](https://wordpress.org/support/topic/leverage-browser-caching-super-cache/) * I have run the Google speed test and I keep getting this message Leverage browser caching. * I have tested six or seven different cache plugins and the results are much the same. * For Super cache, it says to Set expires header but the check box is greyed out so I can’t activate it. * Do any of you clever coders know what to do as this stuff totally confuses me. * Thanks Viewing 4 replies - 1 through 4 (of 4 total) * Thread Starter [hadders](https://wordpress.org/support/users/hadders/) * (@hadders) * [9 years, 8 months ago](https://wordpress.org/support/topic/leverage-browser-caching-super-cache/#post-8185121) * A few months ago I was getting speed test of 87 for both mobile and desktop. Now its 56 and 66 and all I have done is add three posts. * [David Artiss](https://wordpress.org/support/users/dartiss/) * (@dartiss) * [9 years, 8 months ago](https://wordpress.org/support/topic/leverage-browser-caching-super-cache/#post-8185153) * Hi [@hadders](https://wordpress.org/support/users/hadders/), * I’ve no tried Super Cache but to add the Set Expires Header, it will need to write to your .htaccess file – maybe it can’t access this? Have you checked their documentation on what to do in this case – it might be worth questioning this on their own forum at [https://wordpress.org/support/plugin/wp-super-cache](https://wordpress.org/support/plugin/wp-super-cache)( assuming it’s WP Super Cache you’re referring to). * The question, though, is – does your site feel any slower? This is always a personal thing but I try not to get too wrapped up on what these sites return as a number. Follow their advise, yes, but if the site seems fast enough I wouldn’t spend too much time chasing the final figures 🙂 * Thread Starter [hadders](https://wordpress.org/support/users/hadders/) * (@hadders) * [9 years, 8 months ago](https://wordpress.org/support/topic/leverage-browser-caching-super-cache/#post-8188446) * Hi [@dartiss](https://wordpress.org/support/users/dartiss/) – that’s a good point about whether it feels right. Dang metrics huh. Cheers for the response. * [David Artiss](https://wordpress.org/support/users/dartiss/) * (@dartiss) * [9 years, 8 months ago](https://wordpress.org/support/topic/leverage-browser-caching-super-cache/#post-8189202) * As I said, it is a personal thing – I just feel you can sometimes spend too long chasing the numbers. For me the important part is their recommendations and trying to implement as many as possible. And, yes, how the site REALLY looks and feels. * Also, you have to remember that some of these recommendations come with caveats as they have possible side effects – caching, for instance, often means that changes you may make to to a post or the site generally may not show up immediately( and if, like me, you forget that it’s down to the caching you can end up spending a lot of time scratching your head wondering what’s happened!). * I also remember a discussion on here recently where a user was being recommended by one of these sites to add a cache plugin but he found, when testing, that it added little to the end score and, in some cases, even made it slower (probably due to the overheads of the plugin running). I suspect this is because often the other recommendations (around changed to .htaccess) often add caching anyway. * So my recommendation – implement all the recommendations that you can but if it doesn’t improve your score then, well, probably don’t bother. When you’ve done all you can stop worrying about that end score – if your site feels quick and your users feel the same then you’ve done what you need to. * If you’re not already using it I would recommend the plugin GTmetrix for WordPress– from your admin it will get scores from PageSpeed and Yslow and give recommendations. I got mine to a ‘B’ score across the board and stopped there.
