Check how your site renders across browsers

Site owners and beginners to web design should know from the start that your site will not and cannot look the same in all browsers and operating systems and some visitors on certain devices will run into some sort of difficulty on your site.

Your website CAN’T look the same in ALL of these browsers, but if it looks poor in most of the popular browsers, then you might have a problem.

In fact – Google specifically states in their Webmaster Guidelines that you should:

QUOTE: “Test your site to make sure that it appears correctly in different browsers: Test your site in as many browsers as possible. Write good, clean HTML. Specify your character encoding. Consider accessibility.” Google, 2020

Check browsers your visitors use in Google Analytics

Google Analytics is a great place to see the browsers your visitors are using. Remember – to design to satisfy your own target audience first.

It is worth pointing out – this site has a very tech-savvy audience – more likely to have modern operating systems with the latest browsers.

You may not.

It is an essential element of good website design that you test your website and how it looks or ‘renders’ in as many web browsers as possible – though it is worth remembering it is impossible to design a website to look exactly the same in all browsers.
