Some of the common issues that can have a negative impact on your mobile-friendly test scores.
If your hosting is not as good as it should be, this will directly impact your site’s performance. Cheap hosting accounts are generally slower and less optimised than more expensive ones. Even the most simple of websites should be hosted on a platform that costs you at least £30 per month.
Large plugins can also slow WordPress sites down. What is important to remember here is that whilst the individual plugin developers do what they can to optimise their plugins, they are not responsible for how many you add to your site.
For example, if you are using a page builder plugin, an e-commerce plugin and an event manager plugin on your site, that’s an awful lot of large plugins, so your site will be slower. Team that up with the theme and hosting mentioned above and your website will run at a snail’s pace.
Most themes do what they can to load images appropriately for the device that is being used to view your site, but if you upload 100s of huge images to your website, this can also slow it down.
Embed, don’t host a video on your site as doing so will simply slow it down, again, this will be more noticeable if you team it up with slow hosting.
If your DNS hosting is slow, your site is going to be slow because your DNS affects how quickly a visitor connects to your website (before they even see it). Slow DNS can make people go back to the search results to look for another website before they have even read anything on your site.
Your website is your 24/7 marketing tool, so hosting it somewhere that charges you £5 per month is counter-productive. We recommend that you should invest at least £30 per month in hosting your site, for a basic website. Larger sites need more resources, so more investment will be required.
Add a caching plugin to your site.
We recommend WP Rocket for caching stuff on your website. It’s a premium plugin, but it’s worth the money as it makes a huge difference and integrates with Cloudflare.
Moving your DNS to a faster host.
Cloudflare is a premium DNS hosting platform with a built-in cache (yes, another one) and additional security options. Moving your DNS to Cloudflare alone can make your site quicker right away. There are paid and free options on Cloudflare, so you can try them before you buy.
Moving your DNS is not something that should be done without full knowledge of what you are doing, if in doubt, speak to the experts.
Compress all your images.
If your site is serving up images that are larger than needed, it’s going to flag issues. This is both in terms of the image dimensions and the file size.
Tools like Smush by WPMU will go through all your images and compress the ones already uploaded and compress new ones as you upload them – this is again something that is not free, but worth the small investment.
Remove unused CSS and JS.
This is a really tricky one as you may not always know what you can or can not safely remove. If you are using a large theme, it may not be possible.
You’ve invested time and money in your website design, build and content, so not bothering with making sure it’s mobile-friendly can harm your rankings and you will miss out on winning potential customers in the search results.
