There are simple SEO practices that you can use that will help improve page speed. A key factor in slowing down page speeds is images. More often than not, images will make up a lot of a page and therefore can slow it down. Being able to optimise and compress these images can have a positive effect on page speeds.
Optimising your website code is another useful way in which you can improve your page speed. Having unnecessary spaces within your code can be detrimental to the performance of your page so getting rid of these spaces can be a subtle improvement to the site.
Looking at your server response time is one other idea that can improve your page speed. If there is a lot of traffic heading to your site, it can put a strain on your server and therefore effecting speeds all over the site. If a servers response time is anything over 200ms, it would be worth looking at resolving any issues to ensure that this doesn’t hinder your page speeds.
After making these adjustments to your pages, now is a good time to see how they have improved your pages speeds. There are many tools that can do this but google page speed insights is a good place to start. It will start scanning your site for issues and opportunities to further improve your page speeds.
