There are many elements to look out for to ensure your website complies with a mobile-first design, however, our team have compiled six key ranking factors that the search engines will be measuring your site against.
When showing content on smaller screen sizes, it is critical to make sure it is still readable. “Text too small to read” is one of the main issues that flag up when Google is crawling websites for mobile usability. Our team recommends that your font is at least 16pt for mobile web pages.
Your website should contain high quality, rich imagery, whilst ensuring that it is optimised so as not to increase page size and loading times. We would recommend JPGs being 80-100kb in size for both mobile and desktop to avoid slow-loading imagery, with PNGs being as close to 100kb as they can be, without losing quality.
Buttons should also be adequately spaced out from one another, so that website users don’t unintentionally press the wrong button whilst browsing your mobile site. If a user lands on a page accidentally, they may close the tab, causing a higher exit rate, which in turn can affect your search engine rankings. It is also important for your buttons to be static, and not animate - it may look great on a desktop if an arrow changes shape or direction, however on mobile it can affect your CLS (cumulative layout shift), which is one of the major factors in Google's Page Experience algorithm.
It's important not to strip any content out of the mobile version of your website due to less space. Using the same content across your desktop and your mobile version of the website will ensure that it is just as useful for visitors, as well as including those all-important keywords for the search engines to use when ranking your webpages.
Video content is a great way to engage with users whilst they are on your website. However, because many people browse the web on the go, you must set your video content to not auto-play, as this could eat up a user’s mobile data, and stop them from wanting to visit your website again in the future.
A great website on all devices can make the difference between ranking on page one for your search terms, or not appearing at all, and as the search engine crawlers are becoming more human-like, each improvement we make for the crawlers will be appreciated by our users.
