How to Uncover SEO Growth Opportunities with Competitor Insights and Mobile Analysis

No matter how optimized your website is, there’s always room for growth—and often, the best SEO opportunities are hiding in plain sight.

At Theia Media, we work with businesses across industries that want to compete smarter, not harder. One of the fastest ways to uncover actionable SEO wins is to stop guessing and start benchmarking against the competition.

In this guide, we’ll break down two powerful strategies we use to identify growth opportunities: keyword gap analysisand desktop vs. mobile performance auditing.

1. Find Keyword Opportunities with a Competitor Gap Analysis

If your competitors are outranking you on Google, it’s not always because they’re better—it’s often because they’re showing up where you're not.

A keyword gap analysis lets you compare your rankings against competitors to see:

• What keywords they rank for that you don’t
• Which of your shared keywords they outrank you on
• Opportunities to create content or strengthen pages around missed terms

How to Perform a Keyword Gap Analysis

You can use a tool like Semrush’s Keyword Gap or Ahrefs’ Content Gap, but the strategy remains the same:

• Enter your website domain alongside your top 2–4 competitors
• Generate the comparison report
• Look for keywords that your competitors rank for but your site does not

Example from Theia Media:
Let’s say a local roofing company comes to us with solid service page content, but they’re not getting much traffic. After running a keyword gap analysis against the top 3 competitors, we find dozens of missing terms like “roof maintenance checklist,” “flat roof lifespan,” and “metal roofing Sarasota.”

We now have a clear roadmap for blog content, FAQs, and service page updates that can close the gap and win more traffic.

What to Look For in the Report

• Top Opportunity Keywords: These are high-value terms your competitors rank for that you don’t.
• Shared Keywords You Rank Lower On: Find out where you’re appearing but need a boost in content or backlinks.
• Keyword Difficulty and Search Volume: Target those with good search volume and low-to-moderate difficulty.

This analysis not only uncovers what’s missing, but it helps prioritize what to tackle first for the fastest return.

2. Compare Desktop vs. Mobile SEO Performance

Google now prioritizes mobile-first indexing, meaning your mobile site is what determines your rankings—not your desktop version. If you’re not auditing both experiences, you’re missing half the picture.

Why This Matters

Let’s say your site performs well on desktop, but mobile users bounce within seconds. That’s a signal to Google—and a problem for your bottom line. A split in performance might mean:

• Your mobile pages load too slowly
• Elements are difficult to interact with
• Content is hidden, too compressed, or missing entirely

How to Analyze Mobile vs. Desktop SEO Performance

To do this, you’ll need access to Google Analytics 4 (GA4):

1. Log into your GA4 property
2. Navigate to:
   Reports > Acquisition > Traffic Acquisition
3. Click “Add comparison” at the top
4. Select Device Category and choose "Mobile" and "Desktop" for comparison

You’ll now see how users behave on each device, broken down by traffic source.

Look at key metrics such as:

• Bounce rate or engagement rate
• Session duration
• Conversions (form submissions, purchases, etc.)
• Organic traffic growth over time

Example from Theia Media:
We worked with a home remodeling business that was seeing solid desktop traffic but flat growth on mobile. Their mobile bounce rate was over 80%. Upon review, we found their “Get a Quote” form wasn’t responsive and required horizontal scrolling. A 15-minute form redesign dropped the bounce rate by 30% and doubled mobile leads in 60 days.

What This Tells You

This report gives you insight into:

• Whether your mobile SEO strategy is paying off
• Where to prioritize UX fixes
• How users interact differently by device

It’s also a great way to segment the impact of changes. If you implement schema markup or a content update, you can track which device segments respond best and adjust accordingly.

Conclusion: SEO Wins Are Hiding in Your Data

You don’t need to reinvent your website to grow your traffic. Sometimes, the biggest wins come from simply paying attention to the right signals.

At Theia Media, we believe smarter strategy beats guesswork every time. If you're not ranking where you should be—or if traffic isn’t converting—these two techniques can unlock valuable answers fast.
