Mobile-Friendly Checker

A mobile-friendly website is one that displays properly and functions well on mobile devices without requiring users to zoom, scroll horizontally, or struggle with touch interactions. Key characteristics include: responsive design that adapts to screen sizes, readable text without zooming, properly sized touch targets, no use of incompatible technologies like Flash, and fast loading times on mobile networks.

Google uses Googlebot Smartphone to crawl and evaluate websites for mobile-friendliness. The evaluation checks for: proper viewport configuration, readable font sizes (16px+ recommended), adequate tap target sizing (48px minimum), content that fits within the viewport without horizontal scrolling, and absence of incompatible technologies. Google also considers Core Web Vitals metrics for mobile performance.

Mobile-first indexing means Google predominantly uses the mobile version of a website's content for indexing and ranking. Since March 2021, Google has used mobile-first indexing for all websites. This means if your mobile site has less content than desktop, that missing content won't be indexed. Responsive design ensures content parity and is the recommended approach.

Google recommends a minimum base font size of 16px for mobile devices. This ensures text is readable without zooming. For secondary text like captions or labels, 14px is the absolute minimum, though 16px+ is preferred. Using relative units (rem, em) based on a 16px root allows for better accessibility as users can adjust their browser's default font size.

The standard viewport meta tag is: <meta name="viewport" content="width=device-width, initial-scale=1">. This tells browsers to set the viewport width to the device width and start at 1x zoom. Avoid adding "maximum-scale=1" or "user-scalable=no" as these disable pinch-to-zoom, which creates accessibility issues.

Google recommends touch targets (buttons, links, form fields) be at least 48x48 CSS pixels with at least 8 pixels of spacing between them. This accounts for the average human fingertip size and prevents accidental taps. The visual element can be smaller if sufficient padding brings the touchable area to 48px. Apple recommends 44x44 points as minimum.

Responsive images automatically adjust their size based on the viewport and device capabilities. This is achieved using the srcset and sizes attributes or the picture element. Responsive images serve appropriately sized files (smaller images for mobile), reducing bandwidth usage and improving load times. CSS should also include max-width: 100% to prevent images from overflowing containers.

Yes, mobile-friendliness is a confirmed Google ranking factor. Google first introduced the "Mobilegeddon" algorithm update in 2015 specifically to boost mobile-friendly pages in mobile search results. With mobile-first indexing, this is even more critical - Google indexes and ranks based on your mobile site. Pages that aren't mobile-friendly may see significant ranking drops on mobile search.

Responsive design is a technical approach using CSS media queries to adapt layouts to any screen size. Mobile-friendly is a broader term meaning the site works well on mobile devices, regardless of the technical implementation. You can have a mobile-friendly site using responsive design, separate mobile URLs (m.example.com), or dynamic serving. Google recommends responsive design as it's easier to maintain and ensures content parity.

To make your website mobile-friendly: 1) Add the viewport meta tag, 2) Use CSS media queries for responsive layouts, 3) Set font sizes to 16px+ for body text, 4) Size touch targets at 48x48px minimum, 5) Use max-width: 100% on images, 6) Remove Flash and other incompatible plugins, 7) Test with this tool and Google's Mobile-Friendly Test, 8) Optimize for Core Web Vitals, and 9) Ensure content parity between mobile and desktop versions.

Yes! Our mobile-friendly checker supports bulk testing. Switch to the "Bulk Check" tab and enter up to 10 URLs (one per line) to analyze them all simultaneously. This is perfect for auditing key pages across your site or comparing mobile-friendliness across different URLs. You can export results as CSV for further analysis.

Our tool considers pages with a score of 70 or higher as mobile-friendly. However, you should aim for 80+ for optimal mobile experience. A score of 90-100 indicates excellent mobile optimization. Remember that this is a static analysis - real-world mobile performance also depends on factors like JavaScript execution and server response times.
