Google Prioritising Mobile Friendliness in Search Results as a basic ranking factor
Is your Website Mobile Friendly?
What are the consequences of Google prioritising mobile friendliness or making it a ‘ranking factor’– how can your website suffer?
- Could your text size be too small?
- Is your content wider than the page?
- Do you have a poor length of navigation bars, or spacing of links?
- Is your mobile viewport not set?
- Are file sizes of graphic content too big?
- Do you have 3rd Party plugins that are not mobile friendly or is there general confusion in the layout?
- Are elements too close together?
Google can see when visitors just bounce away and might punish poor sites by dropping them in search rankings.

Why is Mobile Important?
Chances are that your website is not fully mobile friendly, so you will need to do some work. Being mobile responsive is not enough, your website needs to be mobile ‘response-able’. In other words, your website’s mobile view should be different from its pc or desktop view or its tablet view, which improves navigation and speed on the smaller screen. For newer websites, this should be part of the basic deliverables.
According to Google:
- Mobile friendly websites show up higher in search results
- These mobile views constitute more than half of Google searches
- The majority of traffic comes from people on mobile devices
- Visitors are 5 times more likely to leave your website if it is not ‘mobile friendly’
Mobile Browsing Stats
Over 70% of buying decisions are made online, even if the purchase is done in store or over the phone after a conversation. In America over 90% of people use smartphones for local search, so this makes mobile friendly websites critical. In addition, over 75% of searches are done at home where there is probably a bigger computer nearby. Furthermore, almost 90% of people click on one of the 10 organic results of a search on page 1. More importantly, over 40% click on the first organic option, while only about 10% click on the second or third result. And, the number of people going to page 2 is in the single percentage figures. Evidently, the majority of buyers are starting their search on a phone, so check out your website’s mobile speed for FREE here.
Core Web Vitals
Core Web Vitals was introduced way back in May 2020. These are a set of metrics that Google uses that relate to website speed, mobile responsiveness, and visual or layout stability. In other words, these metrics are the overall page experience ranking factors.
The page experience ranking factor is a measure of how well people enjoy interacting with a page beyond the information value of that particular page. The 3 Core Web Vitals or additions to the page experience ranking factor include:
Largest Contentful Paint (LCP) – Measures how quickly a page loads – ideally under 3 seconds.
First Input Delay (FID) – Measured interactivity and page responsiveness. Google replaced First Input Delay (FID) with Interaction to Next Paint (INP) as a Core Web Vitals metric on March 12th 2024. This is a ‘metric that assesses page responsiveness using data from the Event Timing API’.
Cumulative Layout Shift (CLS) – Measures unanticipated layout movement on a page. In other words, things that are unexpected and annoying.
*This ‘supposedly’ could include lazy loading, but as long as you add all the dimensions, as in width and height for the placeholder, then lazy loading of the image itself should not make any difference. It relates more to boxes and buttons moving around the page, which happens with a lot of Ad boxes. For accurate explanation check out https://web.dev/cls/ for more information.
“What is a good CLS score?”
To provide a good user experience, sites should strive to have a CLS score of 0.1 or less. To ensure you’re hitting this target for most of your users, a good threshold to measure is the 75th percentile of page loads, segmented across mobile and desktop devices.” Realistically you should be scoring 90 or more for both Mobile and Desktop. All the results should be green.
Update March 2024
Fast forward and the first 3 Core Web Vitals metrics are being paired with the following four existing website signals to round out Google’s stated understanding of overall page experience:
Mobile-Friendly– Measures mobile usability and responsiveness of a page on a smart phone.
Safe Browsing – Identifies security issues on a page, if there are any.
HTTPS – Confirms pages are using an SSL protocol, which makes the little “lock” appear in the top left corner where the url is located.
No Intrusive Interstitials – Determines if pages have unwanted pop-ups.
Google has laid down the gauntlet, and we need to get in line with their current expectations… or else we risk losing valuable business! Don’t let Google Prioritising Mobile Friendliness affect your business negatively. Check how your website scores at Google Page Insights. Remember; You want to score 80 to 90 or more.

What makes a website slow?
There are lots of reasons a website could be slow. Here is a list to get you started. Some can be fixed by a website user or webmaster. Some need the technical input from an experienced developer.
Hosting is always the first port of call. Your hosting may be poor quality. Or the server software, the php software version could be outdated. There could be a caching issue.
Using a CDN Content Delivery Network such as Cloudflare could help deliver the website faster in different parts of the world.
Website Javascript or CSS may be an issue. Or the website platform software such as WordPress may need updating. The actual website code could be heavy or bloated. The site may have a Theme which may have unused or unrequired elements, making the site heavy or full of 404 pages. Likewise too may 301 redirects can slow things up.
Design elements may have moving parts which causes delays.
Content such as photos or videos may be too big and be causing delays.
Pages may not be technically well optimised.
Plugins or extensions may need updating. Or one could be causing a conflict with another. There could even be too many plugins installed. One or more could be outdated or has not been updated recently by its developers.
It is possible that there is Malware injected in to the website – hopefully not.
And there may be other reasons. If all of this makes sense to you then take the FREE Google report and get to work to improve things. Or send the details to your web design agency and tell them to get it sorted asap.

Google Page Speed Insights Explained
Google Page Speed Insights or Page Experience is a combination of current Google ranking factors plus a recent set of performance-related factors called Core Web Vitals. These current signals are Mobile friendly, Safe browsing, HTTP or security and lastly No intrusive interstitials.
What are Googles Core Web Vitals?
Ostensibly a set of three performance related core metrics that look at the loading, the interactivity and visual stability of a page., Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS).
Largest Contentful Paint (LCP)
Largest Contentful Paint (LCP) measures the loading performance of the largest piece of content on a web page. LCP looks at the time taken for Google to render or deliver “the largest image or text block visible within the viewport, relative to when the page first started loading”. Google says, the LCP of a page should be less than 2.5 seconds.
First Input Delay (FID)
The First Input Delay (FID) metric measures the interactivity of a web page and looks at the time a browser such as Chrome or Safari takes to respond to the user’s first interaction on a page. Examples of interactions include clicking on a link or button, Clicking on a checkbox, Inputting text into a form or selecting an option from a drop-down menu. A good FID score is 100 milliseconds or less.
Cumulative Layout Shift (CLS)
Cumulative Layout Shift (CLS) measures visual stability, a relatively new metric that accounts for unexpected layout shifts on a web page. The idea is to minimise sudden shifts in the content that result in a poor user experience, so strive to have a CLS score of less than 0.1.
Measuring Page Experience Metrics
Google provides a few tools to do this, Google Search Console which has a Core Web Vitals report and a Page Experience report, PageSpeed Insights and Google Chrome Lighthouse Report.
Google Search Console
Google Search Console has two reports to let you to measure page experience metrics accurately for Core Web Vitals and Page Experience. The report categorizes links or URLs into three categories for desktop view and mobile view, poor URLs, the URLs that need improvement and the good URLs or links. Clicking on any report will give you more information about any current issues. You want 100% of your URLs as being good on mobile to improve the Page Experience report.
The Page Experience Report
When your URL’s are showing as good on mobile in the Core Web Vitals report, this then qualifies them for the Page Experience report. Google introduced the Page Experience report in Google Search Console which summarises the user experience of the individual pages on your website. This report combines the Core Web Vitals report with other page experience signals HTTPS or Security, Safe browsing Mobile-friendliness Intrusive interstitials and any Google Ad experience violations. The Page Experience report explains which URLs offer a good user experience along with the number of search impressions over any given period of time. Check your website or page HERE.
Google Chrome Lighthouse Report
Google Chrome you can generate a report directly from the browser, simply load the specific page you want to test, right click anywhere and click on inspect (ctrl+shift+i). Click on resources and navigate to the ‘Lighthouse Tab’ and click on Generate Report, which when finished will give you a complete report that should show you any detected issues in Performance, Accessibility, SEO and Best Practice.
