A desktop preview can make a website look finished while hiding problems customers encounter on a phone. A menu may cover a service description, a floating button may sit over the form, or essential details may disappear at a smaller screen size. A mobile SEO review should examine both the information visitors receive and the steps they take to enquire.
1. Compare the information, not just the layout
Google uses the mobile version of website content for indexing and ranking. Check that your mobile page retains the important service description, headings and supporting information available on desktop. The presentation can change: an accordion can organise a long section, for example. But important content should not depend on a visitor clicking a button before it is fetched.
For a web development service, compare the project scope, delivery process and contact options on both screen sizes. If a customer can understand the offer only on a laptop, make the missing explanation available on the phone as well.
2. Walk through the navigation with one hand
Open the website on an actual phone and try to reach a service from the homepage. Check whether the menu opens reliably, category items expand clearly and the close control remains reachable. Test long labels such as Online Reputation Management rather than checking only short menu items. Look for horizontal scrolling and links that are too close together to select comfortably.
3. Test the enquiry form with the keyboard open
A form that fits an empty screen can become awkward once the on-screen keyboard appears. Enter a name, phone number and email, select a service, and confirm that the submit button remains reachable. Check the error message for an invalid email before testing a successful enquiry. Labels should remain understandable after placeholders disappear.
Watch the interaction between the form and floating controls. A WhatsApp shortcut is useful, but it should not cover a field or the close button of an enquiry popup. Verify that closing the popup returns visitors to the page without leaving scrolling locked.
4. Keep meaningful images readable
Inspect mobile crops instead of assuming that a desktop banner will work at every width. A product detail or an important part of a screenshot should not be cut off. Use appropriate image sizes while retaining clarity. If a visual contains instructions, provide those instructions as readable page text too. For file delivery and alternative descriptions, see our image SEO guide.
5. Use a repeatable acceptance checklist
Choose a homepage, one detailed service page, an article and the contact page. Review each in portrait and landscape, then record the device, URL, issue and expected behaviour. Prioritise problems that prevent reading or submitting an enquiry before adjusting decorative spacing. Recheck the same tasks after a menu, theme or form update.
