What Is Mobile SEO?

Mobile SEO is a type of search engine optimization for websites that focuses on mobile devices. Mobile search engine optimization techniques also ensure that your site functions properly on mobile browsers. Mobile SEO is the practice of optimizing your content to achieve higher rankings and a better user experience.

That’s the basic definition for what is mobile SEO. Next, we’ll go over why mobile SEO is important.

Why Is Mobile SEO Important?

Mobile SEO is important because it ensures that mobile visitors have a good experience that’s optimized for their mobile device. Important factors of mobile search engine optimization include site design, site structure, page speed, and on-page mobile SEO practices.

According to Google, “When people have a negative brand experience on mobile, they are over 60% less likely to purchase from that brand in the future than if they have a positive experience.”

Google also reports that “some people are spending up to 70% of their time on mobile”. And “mobile conversion rates are 47% of the levels achieved on desktop.”

And if you were not aware of this already, Google now uses mobile-first indexing where it predominantly uses the mobile version of the content for indexing and ranking.

As of this writing, the percentage of users who perform Internet searches worldwide with a mobile device is 55% reported by StatCounter and 61% by Perficient.

With those factors in mind, it’s easy to see why mobile SEO is important for every website and brand.

How Does Mobile SEO Work?

Mobile SEO works by optimizing a website and content to achieve higher rankings in search engine results pages (SERPs). Mobile search engine optimization works to improve organic traffic, which is traffic coming to a site from the SERPs.

Google primarily crawls and indexes pages with its smartphone agent. And if you monitor the crawl traffic to your site, you should see an increase in traffic from Smartphone Googlebot.

Because of mobile-first indexing, the mobile version of your website is considered the primary version for crawling and organic SEO ranking purposes.

If your mobile and desktop versions are the same, then you shouldn’t have any significant problems with your site’s performance in the search results. However, if your mobile site serves different content than the desktop site, then you could experience ranking complications with search engine optimization.

The key takeaway here before we move onto the tips for how to improve mobile SEO is that the desktop version of a page’s content doesn’t matter much anymore. When evaluating the relevance of a page to a user’s query, Google prefers the mobile version of your site for crawling, indexing, and ranking.

How to improve mobile SEO

How to Improve Mobile SEO

1. Use a Responsive Design

Google advocates responsive designs for mobile SEO purposes.

So the easiest way for how to improve mobile SEO is to use a responsive design on your website.

With a responsive design, your site has one URL and all pages share the same content for both the mobile version and desktop version.

Responsive design is better than dynamic serving or a separate domain because it makes it easier for Google to understand the content and index it accordingly.

Dynamic serving uses server-side technology to serve a different version of your site to mobile users. The URLs stay the same but the files sent are completely different. 

A separate domain usually refers to a subdomain with an “m.” attached to the domain and it has different content on it. When a user visits your website from a mobile device, the server can detect this and serve the subdomain content instead of the standard content.

Google supports separate domains but only if you make the correct connections between your regular desktop domain and the mobile domain.

2. Improve Your Mobile Site Speed

Speed is now a ranking factor for Google Search. So you must pay attention to it for mobile search engine optimization.

Google gives you access to a free PageSpeed Insights tool that allows you to measure individual page loading speeds on both mobile and desktop and gives you suggestions on how to improve the performance.

The two most important factors for mobile search engine optimization include:

  • LCP (Largest Contentful Paint): This measures the amount of time it takes for the largest element of a requested page to appear in the viewport. A higher score (i.e. faster speed) gives the impression to a user that a page loads faster. Sites should strive for an LCP of of 2.5 seconds or less.
  • FID (First Input Delay): This measure the time from when a user first interacts with an element on your site to when the browser responds to that input. Examples include clicking a link or tapping a button on the page. Sites should strive for a FID of 100 milliseconds or less.

There are a number of optimizations you can make for mobile SEO site speed, many of which fall under technical SEO, including:

Optimize Images and Use Fewer of Them

Use a Quality Web Host

Update to the Latest PHP Version

Transition to HTTP/2

Improve Server Response Time

Enable GZip Compression

Remove Unnecessary Redirects

Fix Render-Blocking Content Above the Fold

Optimize and Minify CSS and Javascript

Use a Contend Delivery Network (CDN)

Use Server-Side Caching or Client-Side Caching

Remove Unnecessary Plugins

3. Optimize for Mobile SEO On the Page

An essential part of mobile SEO is your on-page optimization.

This includes optimizing key areas of the page for your target keywords, including:

  • Meta Title
  • Meta Description
  • URL
  • H1 Tag
  • H2-H6 Tags
  • Body Content
  • Images
  • Internal Links
  • Navigation Menu

A mobile page that includes your keywords in the right places and the correct number of times can rank higher for those queries.

4. Use Structured Data

Structured Data, also known as Schema Markup, allows Google to better understand the type of content you have on your site.

And with good Structured Data in place, your pages can obtain rich results in the search engine results pages (SERP).

For example, Structured Data can get your content listed with review stars, recipe images, and event dates in the SERPs, which can significantly increase the click-through rate for your web pages. It can also display your business’ name, address, and phone number (NAP) right on the SERP listing.

You can use Google’s Structured Data Tool for testing your website and improve it for mobile search engine optimization.

5. Optimize for Local Search

According to Google research, “69% of smartphone users turn to mobile search first in a moment of need.” And “76% of people who search on their smartphone for something nearby visit a related business within a day.”

Therefore, a good mobile SEO strategy will include optimizing for local search, as long as your business serves local customers.

Local SEO can help you capture “near me” searches and localized searches with a mobile device. And a few good strategies for that include:

  • Writing localized content
  • Building local backlinks
  • Setting up a Google My Business Listing
  • Getting customer reviews on Google
  • Adding your business NAP information to your website with Structured Data

6. Specify the Correct Viewport

The viewport is the user’s visible area of a web page and it’s very important for mobile SEO and responsive design.

By specifying the correct viewport, you can ensure that mobile visitors are served the mobile version of your site and not the desktop version.

To optimize your pages correctly, a meta viewport tag must be in the head of the HTML document. This meta viewport tag is what gives the browser instructions on how to control the dimensions and scaling for the page so it is displayed properly for a mobile visitor.

7. Improve Mobile Legibility

If a website is hard to read on a mobile device, then it can cause a poor user experience.

And poor user experiences can lead to a drop in rankings if your content cannot meet the needs of your users.

Use large fonts and good spacing being paragraph lines so the content is more legible and easier to read on a mobile screen.

8. Improve Tap Target Sizes

According to Google Developers, “interactive elements like buttons or links [need to be] large enough, and have enough space around them, to make them easy to press without accidentally overlapping onto other elements.”

Google Developers goes on to say that “A minimum recommended touch target size is around 48 device independent pixels on a site with a properly set mobile viewport. The 48×48 pixel area corresponds to around 9mm, which is about the size of a person’s finger pad area.”

9. Don’t Use Interstitials or Pop-Ups

Google has stated that “Pages that show intrusive interstitials provide a poorer experience to users than other pages where content is immediately accessible.” And, “pages where content is not easily accessible to a user on the transition from the mobile search results may not rank as highly.”

Therefore, it’s best not to use interstitials or pop-ups on the mobile version of your site.

The biggest causes for concern include:

  • Showing a popup that covers the main content, either immediately after the user navigates to a page from the search results, or while they are looking through the page.
  • Displaying a standalone interstitial that the user has to dismiss before accessing the main content.

10. Monitor, Analyze & Test

As with all SEO practices, optimizing for mobile SEO is not a one-time project.

You need to continue to monitor your results, analyze the data, and test new strategies to find more winning opportunities.

Make sure to set up and regularly check your Google Analytics and Google Search Console for trends in keyword rankings, click-through rates, bounce rates, dwell time, and other metrics for your content.
