Before making a purchase, you should never skip your research. Compare one hosting provider to another, even if it takes ages. Make sure you purchase the best hosting service, which has at least 99.5% server uptime, under 200ms server response time, and abundant bandwidth.

Problem #3: Too many large, unoptimized images

Images play a significant role in making your articles more engaging. However, you need to remember that high-resolution images cause heavy loads for your website. Uploading your pictures without compressing it is one of the critical problems to your website being slow.

The common desktop screen resolution is 1920×1080, and the mobile phone’ is mostly 720×1280. Therefore, the images you upload on your website shouldn’t overkill both of the screen resolutions.

Problem #5: WordPress is outdated

WordPress is an open-source platform; users can expect updates even for the tiniest errors any developers can find. Apart from fixing errors, the updates also cover speed and security improvements.

Fix: Update (and auto-update) WordPress

Punch the Update button every time it pops up, or opt for enabling automatic updates. However, before updating WordPress, you need to ensure your plugins and theme are compatible with the new version. Also, make sure that you get all your data backed up.

Leaching or hotlinking happens when someone uses your images for their websites by directly linking them to your website. This situation is harmful, as it can reduce your bandwidth. And as more traffic is directed to your website, hotlinking will also result in the lagging website.

Fix: Disable hotlinking

Similar to enabling the gzip compression, access your .htaccess file to disable hotlinking. Give a little edit to the code, and that’s how you block websites to directly link your content.

Problem #7: Too many, poorly coded plugins

We’ve seen how ineffective coding may harm your site’s performance. This can happen with the plugin’s code too. While adding many plugins adds load to your website already, having poorly coded ones can double the load.

It’s tempting to add more plugins to keep stacking features on your site. On the other hand, five to ten plugins are enough for a WordPress website. Therefore, tidy up your plugins frequently. You can use Query Monitor to help you eliminate plugins that perform poorly.

Problem #8: Too many HTTP and database requests

Plugins and themes often hold information from other websites. As a result, they contribute to external HTTP requests. Typically, the theme’s codes contain thousands of lines, resulting in heavier loads for your website.

Fix: Use a trusted, lightweight theme

Free themes are often targets for malware and virus threats. Therefore, avoid using one, especially from unfamiliar developers. Also, you ought to always make sure you use the latest version of it.
