Good hosting plan

Your hosting plan is one of the most important aspects that determines the performance of your site. When you are starting out, most likely, you would go for a shared hosting plan. Some of the shared hosting plans are really good, as they focus on speed optimization as well. However, since it is a shared service, you might occasionally face troubles in the allocation of resources.

A managed WordPress hosting service would be great for your site performance if you have considerable traffic coming to it.

Use a good theme

A bloated WordPress theme can considerably slow down your store. If you are using a versatile, multi-purpose theme for your site, chances are high that it comes with a lot of bells and whistles. This might be really good theoretically, but not so much practically. The success of your WordPress site will be dependent on how you are able to focus on your domain. When you try to do that, a lightweight, specialist theme will be a much better option than having a theme with features you don’t need.

Use quality plugins from trusted developers

Another aspect that has a major influence on your site’s performance is the plugins that you use. In the WordPress ecosystem, you will find numerous plugins with varied capabilities. The trick is to use plugins only when you really need them. Just because a feature is good to have, you don’t have to implement that on your site. If it really helps with your site’s user experience, you can consider adding it to your site.

Moreover, when you are choosing plugins, make sure you are getting them from developers who follow WordPress coding standards. A badly-coded plugin can do more bad to your site than good. So always do a bit of research on the developer before getting one. If you are downloading a free plugin from WordPress plugin repository, check the star rating, user reviews and updates of the plugin. In addition to the repository, you can find good plugins from WooCommerce extensions store, ELEX, YITH, PluginHive, WisdmLabs, etc.

WordPress allows you to upload video and audio files directly. However, it is not a great idea as it may slow down your site. This is why experts advise to use a third party video hosting tool like YouTube or Vimeo to upload videos. After uploading videos to the hosting service, you can embed them to your WordPress post. To embed a video file, you can simply paste the url to the post, and WordPress will embed it automatically.

You can disable these scripts altogether, or merge them into one to optimize & speed up your WordPress site.

Disable pingbacks and trackbacks

When one of your pages or posts receive a backlink from another site, you will get a pingback. This might appear to be a useful feature, but it uses a lot of server resources by generating requests back and forth. Experts suggest to disable this feature on your WordPress admin itself and use some other tools to track backlinks to your site. On your WordPress admin panel, you can find the option to disable pingbacks and trackbacks under Settings > Discussion.

Optimize home page

Your homepage is where majority of your site user land on. So, it is important to offer the best experience to them on this page. Make sure to keep it uncluttered and well organized. Keep excerpts of your posts, and display an optimum number of posts. Also, make sure there are no unnecessary widgets for social sharing or other features that are causing hindrance to a better user experience.

Split long posts to pages

Informative long posts are a great way to please users as well as search engines. However, long posts would also have a lot of images, and hence might take more time to load. One strategies you adopt here is to split a long post into multiple pages. You can use the WordPress default tag for this, or use a plugin like WP-PageNavi to optimize & speed up your WordPress site.

Split comments to pages

Comments on your blog post will be a great indicator of customer engagement. However, having a large number of comments can reduce the page loading speed as well. To avoid this, WordPress has a setting, where you can specify how you want to split comments on your posts. You find this options on the WordPress admin panel (Settings > Discussion).

Optimize scheduled tasks

There might be several scheduled tasks running on your site’s background, such as backups or cron jobs. You need to optimize these tasks to ensure that they are not affecting your site performance. For example, running backups during a low traffic period would not affect user experience that much. Similarly, you can check out crawl reports on your Search Console also to ensure there is no impact on performance.

Update PHP

You need to make sure that your site is running on the latest version of PHP. If you are using one of the WordPress recommended hosting service providers, chances are high that it is regularly updated. However, if in case you find out that your website is not running on the latest version of PHP, you can request them for that.

Regular update of WordPress and related tools

As you know, one of the salient features of WordPress is that it is regularly updates. The entire set of tools in the ecosystem follows this pattern actually.
