What is mobile SEO?
Mobile SEO (Mobile Search Engine Optimization) is a practice of optimizing your website to perform well on mobile search engine results. Mobile SEO encompasses a broad range of practices, from page speed and metadata optimization for mobile users to limited popups and mobile sitemaps.
The ultimate goal of mobile SEO is to make website text, images, and videos easily accessible for those browsing on their smartphones, tablets - basically, anything that’s not a desktop. Mobile SEO practices also ensure that your site’s UI and navigation take mobile users into account.
Why is Mobile SEO Important?
For starters, ever since 2019, mobile-first is the default way Google crawls and indexes new websites. As for the older ones, mobile usability plays a massive factor in good overall page rankings.
On top of that, mobile search is slowly overtaking a lot of desktop experiences. If you take a look at Statista, back in 2013 only around 27% were using their mobile devices for search engine visits, whereas in 2021 this number grew all the way to 61%. Needless to say, this trend is not going anywhere.
It should be in every website owner’s best interest to learn about mobile SEO practices and how to implement them, and this is what we’re about to cover.
Mobile SEO Best Practices
So what does it actually take to make your website optimized for mobile search?
Best mobile SEO practices fall under these nine categories:
- Mobile-friendly website configuration
- Optimized titles and meta descriptions
- Responsive images
- Exceptional mobile UX
- Optimized mobile website speed
- Structured data for mobile pages
- Ensuring content accessibility
- Optimized video and animated content
- Submitting mobile sitemaps
Let’s dive into each of these mobile SEO aspects with recommendations for proper mobile site optimization.
Implement a mobile-friendly website configuration
Three most popular ways to ensure mobile visibility are responsive design, dynamic serving and separate URLs for desktop and mobile versions of your website. They differ based on the solutions you need for your HTML, CSS as well as URLs used to access your web pages.
Responsive Web Design - Recommended
The concept of responsive design is rather self-explanatory - your website is supposed to respond and adapt to the environment in which it is being used.
Responsive web design is basically a mix of grids, layouts and CSS that all come together and react to device characteristics, serving content in a way that’s accessible to that reader.
Among its biggest perks is the fact that your HTML and CSS remain unaltered, meaning you serve one and the same version of your page everywhere, the only difference is how it shows up. You also don’t need to worry about separate URLs and canonical tags to explain relationships between different versions of the same page.
The only need to be concerned with including the viewport element and using CSS media queries correctly.
This way of adapting your website to different screen sizes involves serving different HTML and CSS depending on the user’s devices.
Vary HTTP header is the key factor in the success of this configuration. You should use it to specify which version of your website is supposed to be served at which instance - those browsing on a Samsung S7 tablet should get its version, whereas those using iPhone 13 should get their respective design.
The biggest downfall of this mobile SEO method is that you have to design a website version for all popular devices. With the level of technological advancement we’re witnessing, this method for a mobile-friendly website is hardly scalable.
This configuration is also pretty self-explanatory - all of your website versions not only serve different CSS and HTML, but also have different URLs.
It’s by far the most outdated and the least scalable way to improve your mobile SEO, even Google itself does not recommend it. Plus, it’s a pain to manage. If for whatever reason you’re forced to use it, make sure your <link> tag with rel="canonical" and rel="alternate" elements are on point, otherwise, you risk duplicate page issues and broken website structure.
Optimize titles and meta descriptions
The best metadata optimization practices for general and mobile SEO aren’t all that different. Your meta title is a ranking factor and needs to contain a focus keyword, whereas your meta description should be a good summary of your page content, include an action verb and in general be well written.
The only additional aspect to consider is character length. As of recently, Google increased mobile meta title length to 78 characters, whereas meta descriptions get 120 characters. If you compare that to desktop’s 70 characters for meta title and 150 characters for meta description, you’ll see that you have to make sacrifices in how much information you put in there if you want both mobile and desktop versions to be fully displayed on SERPs.

Optimize images for mobile devices
Visuals are an inseparable part of a quality mobile website, but don’t forget to optimize them.
Featured or hero images, if not optimized, can easily take up several folds of mobile screen. Knowing mobile user habits, it’s easy to assume that if people need to scroll a lot to get to the actual content, they will quickly leave the website. To have your featured and decorative visuals optimized for mobile SEO, adjust their size to fit into the top of a mobile screen or remove them altogether.
But how do you handle images that are integral to your website, such as product photos? They can still negatively affect your mobile SEO and mobile site speed if not optimized, but you can’t remove them.
To ensure your images comply with the best mobile SEO practices, you should efficiently encode them:
- Implement responsive images
- Compress images
- Serve images in mobile-optimized formats, such as WebP
- Use CMS plugins or image compression apps

Improve mobile user experience
The way mobile users interact with their devices and the content on them is drastically different from behavior seen on desktop. Adapt to that for a successful mobile SEO strategy by considering these three foundational mobile UX aspects.
A mobile user opens your website and they don’t need to zoom in, scroll or squint. Instead, they can immediately start reading.
That’s what a mobile-optimized website content should look like. To get there, you need to take care of a few aspects:
- Font size. At least 16px is advised for responsive websites.
- Contrast. People often use their mobile devices outside, plus the screen size is significantly smaller. If there isn’t sufficient contrast between your background and text or images, the content will be difficult to read.
- Paragraph length. Break up your content into short paragraphs, 2 or 3 lines at most. The idea here is to avoid paragraphs that stretch further than a single screen fold.
- Line length. When creating content, orient towards 60 characters per line.
Let’s face it, pop-ups might be among the most hated on-page features. Nonetheless, a lot of time they get the job done. If you have pop-up ads present on your mobile website, make sure you follow Google’s guidelines for appropriate interstitials and banners.
If you have to display a cookie consent, log-in, or banner pop-up, make sure it does not take up the entire screen, has a clear option for closing it and does not interfere with the reading experience too much.
Element size and placement
Element placement to allow easy mobile on-page interaction is crucial for mobile SEO. This is especially true with buttons - there is nothing more frustrating than misclicking and ending up somewhere you never intended to be.
Three main notes here:
- Use negative space. Unlike when designing for desktop, with mobile devices, the more space you have around a clickable element, the better.
- Place buttons strategically. Instead of leaving them somewhere at the top of the page, place social share buttons in a sticky sidebar or bottom bar.
- Space out links. Any contextual links you place in your text should be far enough apart that mobile readers could click on them without any issues.
Take care of mobile page speed
Every user expects a fast-loading website, especially when they’re browsing on mobile. That’s why mobile page speed should be one of the utmost priorities for an effective mobile SEO strategy.

Optimize for local searches
According to Google itself, 94% of all local searches happen on mobile devices. If you’re running a local business, take advantage of the perks GPS is providing for you and optimize your website for local searches.
A well-optimized website for local searches on mobile should:
- Provide basic company information. Display business name, address, phone number, and other necessary info in multiple places on the website. It’s best to place this information in the footer and the contact page.
- Display reviews. Ensure that if customers leave reviews about your business on review sites or on Google, they find their way to your website. Social proof is one of the most likely ways to attract people browsing for local services on the go.
- Create local content. While it’s great to rank for “Guided tours near me”, don’t limit yourself to that. Do research around long-tail local search queries, such as “Top things to do in Toronto during the summer”, create valuable content with tips and you can attract people searching for local attractions.
Tip: Quite a few businesses still haven’t claimed their Google My Business listing. Don’t fall behind and make sure you connect with people searching for your services on Google Maps.
Implement structured data
Just like desktop results, mobile SERPs display rich results. You want to capture as many of them as possible because rich snippets significantly improve click through rates.
Any structured data markup you implement for the desktop version of your website should work just fine on mobile as well.
We already discussed the importance of optimization for local search queries. Structured data can help here too! The emphasis should go on Local Business schema markup, preferably using JSON-LD.
Implementing it allows you to display panels with detailed business information including working hours, customer reviews, contact information, and more. It’s incredibly valuable - you immediately inspire trust in your business and provide people with all the information necessary to choose you over your competitors.
Make all content accessible for search engine bots
Sometimes website owners think that the amount of content they display on the desktop version of their website feels crowded on mobile and decide to hide some of it.
With Google being mobile-first, whatever is hidden from the mobile version is hidden from Google, meaning you should make the same version of the website accessible for all users.
Tip: Unsure of what Google sees when it visits your mobile site? Use “Fetch as Google” and look at your robots.txt files to see if anything is being hidden from mobile users.
Optimize video and animated content
You don’t want mobile users seeing broken videos or blank spaces instead of animations, it’s bad for user experience and for mobile SEO.
Any animated or video content you embed in your website should come in HTML5 format. It’s optimized and designed to function on all browsers of all devices. Video content displayed using some other software, such as Flash, might not work on mobile devices, causing broken links and low mobile rankings.
Create mobile sitemaps
If your website runs on dynamic serving or separate URL configuration, you would benefit from a separate mobile sitemap. This way, Google has an easier mapping out your mobile site structure and what mobile visitors are seeing.
Note that if you have responsive design implemented, a regular XML sitemap is more than enough to help Google understand your site structure - yet another reason to choose responsive design.
Mobile SEO tips for eCommerce websites
If you’re running an eCommerce store, mobile SEO should be an even bigger priority of yours. Stores without an optimized mobile version are at risk of losing many, many customers.
On top all of the best general mobile SEO practices listed above, make sure to:
- Set up canonical tags. In some cases, for instance when using Shopify, your product pages might end up being duplicated on different URLs (e.g. main and collection product pages). Set up canonical tags pointing to your main product page to avoid duplicate content issues.
- Sort out filter indexing. Filtering is an incredible way to ease site navigation and improve mobile SEO of your eCommerce store. However, if you create too many filters and all of the pages are indexed, it can once again create duplicate content issues. Organize the number of filters and their pages by following the best product filtering practices for mobile SEO.
- Use eCommerce tools for mobile SEO. WordPress SEO plugins or Shopify apps for SEO are designed to improve your store’s performance on mobile search.

Test your website mobile optimization
Now that you know what steps exactly you need to take to have a mobile-friendly website, it’s time to figure out how well your website is doing in the mobile SEO department.
There are main tools and ways to test how well optimized your website is for mobile users.
Here is a bit on the three main ones.
Google search console
Mobile usability report in your Google Search Console gives you a great understanding of where you stand in terms of mobile SEO. Based on how your page performs on mobile in the eyes of Google, it can receive either a Valid or an Error verdict.
Some of the more common errors include your content being wider than screen, incorrectly set viewport tags, text being too small to read or elements appearing too close together.
You want to take all warnings from Google Search Console seriously and put effort into resolving them for good mobile SEO.
Tip: Whenever you fix mobile SEO issues you noticed in your Search Console report, submit your page for indexing. The faster Google sees you made the necessary changes, the faster your page will start ranking well.
Google's Mobile-Friendly Test
To test how mobile-friendly a page of your website is at any given moment, you can submit it for Google’s Mobile-Friendly Test. Not only will this mobile optimization checker specify if it comes across any issues while crawling the page, it will also give you a snapshot of what it looks like to mobile users in real time.
Check how your mobile website looks
There is no better way to spot mobile SEO and usability problems than seeing what your mobile version actually looks like and how it performs.
If you’re a Chrome user, use DevTools to view your page on mobile. Toggle Device Mode at the top left of the DevTools dashboard. You can also adjust screen resolution at the top of the page to take a look at a specific size device you’re interested in.
Mobile SEO: summary
