WordPress theme checklist

Mobile friendly

It is important that your website performs adequately and is readable and usable on all available devices. From November 2016 onwards, it has been more popular to browse on mobile devices than on desktops and Google has now also adopted ‘Mobile-first indexing.’ This means that your sites’ ranking in Google for every device is determined by how mobile-friendly your website is. Determine how mobile-friendly your theme is.

Last update

When was the theme last updated? If that was over a year ago, it is likely that the theme is no longer actively maintained. This can incur some obstacles regarding performance, compatibility and safety issues in particular. We also advise you to check whether the theme is compatible with the latest version of WordPress.

Number of users

View the number of ‘Active installs’ on or the number of sales on If a new theme does not have many users yet, it will automatically be a riskier choice. You won’t know how well it is going to perform in the market and how well the theme will be maintained in the future.


The number of theme reviews in combination with them being positive or negative gives you a reasonable impression on the theme’s quality. The more great reviews, the better. In addition to checking the positive rating, it is always a good idea to read what other users have to say about the theme.

Browser support

Verify that your theme works in all the usual browsers. You can find the most globally used browsers on Stat Counter Global Stats. Currently, these are Chrome, Safari, UC Browser, Firefox, Internet Explorer and Opera.


If you run into problems with your theme, you should be able to find answers to your questions or to ask someone for assistance. Are there FAQs available on the theme and do the developers respond quickly to support questions? You can test this for yourself by contacting them.


You want your website to be accessible and usable for as many people as possible, and that includes people with disabilities. You can easily test a website’s accessibility with AxE – the Accessibility Engine.

W3C validator

W3C stands for World Wide Web Consortium. This is an organisation that maintains a number of important Internet standards. They design guidelines for the use of HTML, XHTML, XML, CSS and web content accessibility. Your website should meet all these guidelines. You can easily test your theme with the W3C validator. terms and conditions
