Mobile vs desktop parity audit
Content, headings, links, schema, robots tags, and alt text compared on every template, with gaps ranked by impact.
The Problem
Your Site Ranks on Desktop and Slips on Every Phone
It shows up once most visitors arrive on phones. Mobile pages carry less content, load slower, and hide key copy behind taps, and Google judges the site by that version.
Hidden content
Reviews and FAQs vanish from the mobile version.
Hidden content
Restore the same primary content on mobile, using tabs or accordions to save space.
Missing markup
Structured data exists on desktop pages only.
Missing markup
Add the same schema to mobile templates and validate it.
Slow loads
Largest Contentful Paint sits in red on phones.
Slow loads
Compress hero images, preload key assets, and trim scripts on mobile templates.
Pop-ups
A full-screen pop-up covers content on arrival.
Pop-ups
Replace it with a small banner that leaves the page readable.
Your desktop page has 900 words, reviews, and an FAQ. On a phone, a theme setting hides the reviews, the FAQ doesn't load, and a full-screen pop-up covers the first paragraph. Google indexes mostly that mobile version, so the details that won your rankings stop counting. Largest Contentful Paint sits in red on 4G, and buttons are too close to tap. Each week this runs, phone searchers bounce to competitors whose mobile pages simply work.
We start by comparing what Google's smartphone crawler sees with your desktop pages, template by template. Missing copy, structured data, links, and image alt text come back into the mobile HTML. Then we fix mobile Core Web Vitals, replace intrusive pop-ups, and space tap targets so pages work with a thumb. Every change is tested with URL Inspection and on mid-range phones. Your mobile pages carry full weight in search, not a trimmed copy.
Mobile and desktop compared
Each template checked for missing content, markup, links, and alt text on mobile.
Mobile Core Web Vitals fixed
LCP, INP, and CLS tuned for phones on mobile networks, not just a fast laptop.
Tap-friendly layouts
Buttons, menus, and forms spaced and sized so every action works with a thumb.

Compare Options
DeveloperLook vs Speed Plugin vs Generic Agency
A speed plugin can lift scores quickly for little money, and a general agency covers content and links. Phones need parity, speed, and layout fixed together, so here is how they compare.
| Feature | DeveloperLookBest fit | Speed plugin | Generic agency |
|---|---|---|---|
| Content parity check | Every template, mobile vs desktop | Not covered | Rarely checked |
| Mobile speed | Fixes in templates and code | Caching and compression, quick wins | Advice passed to developers |
| Pop-ups and tap targets | Reworked and tested on phones | Not covered | Flagged in reports |
| Structured data on mobile | Matched and validated | Not covered | Sometimes checked |
| Testing method | URL Inspection and mid-range phones | Lab scores only | Desktop crawler by default |
| Upfront cost | Fixed scope from $700 | Free or a small yearly fee | Monthly retainer |
| Risk of breakage | Changes tested on staging | Can break layouts or scripts | Depends on the developer |
| Code ownership | Fixes live in your theme | Tied to the plugin | Varies by agency |

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built and launched websites for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Website Owners Trust Us With Search on Phones
As a mobile SEO company, we test on phones people actually own and judge pages by what Google's smartphone crawler sees. Desktop scores don't count here.
Mid-range phones, not laptops
We test on mid-range Android phones and iPhones over mobile networks. A page that flies on a developer laptop can still crawl on a commuter's phone.
Google's smartphone view first
We judge each page by the rendered HTML in URL Inspection, the view of Google's smartphone crawler. That is the version Google mostly indexes.
Parity before polish
Missing content costs more than a slow animation. We restore what mobile visitors and Google can't see before tuning speed scores.
Google's mobile guidance cited
Each fix links to Google's mobile-first indexing or Core Web Vitals documentation. Your team can check exactly why a change matters.
Honest about scores
A perfect Lighthouse score isn't the goal, and lab scores can differ from real visits. We report field data from real users next to lab numbers.
Fixes stay in your site
Every change lives in your theme or codebase, not in a paid plugin you must keep. You keep the gains if you stop working with us.

Good fit
Sites ranking lower on phones
Your Search Console data shows strong desktop positions, but mobile clicks lag behind, and most of your visitors arrive on a phone.
Businesses with a separate m-dot site
Your mobile site runs on an m-dot subdomain with fewer pages and shorter copy, and that thinner version is the one Google indexes.
Stores with heavy product pages
Your product pages crawl on 4G, and PageSpeed Insights flags Largest Contentful Paint in red for mobile visitors.
Teams cleaning up mobile pop-ups
Your email pop-up covers the whole screen on phones, and you want the sign-ups without hurting mobile friendly SEO.
Agencies needing mobile engineering
Your agency handles content, and you need a mobile SEO agency partner that fixes templates, speed, and parity under your brand.
Not a fit
Site isn't responsive at all
Your site breaks on phones and needs new layouts, not fixes. Our Responsive Web Design Services rebuild the templates first, and mobile search work comes after.
Only speed scores matter
You only want Core Web Vitals in the green, and content already matches on both versions. Our Core Web Vitals Optimization service fits that narrower job.
App store rankings
You need your iOS or Android app to rank in the App Store or Google Play. That is app store optimization, which this service doesn't cover.
Budget under $700
You can't spend $700 yet. Run key pages through PageSpeed Insights and compare mobile and desktop copy yourself: if both look right, you may not need us.

Mobile SEO services start at $700 for a parity audit and content fixes on up to 3 templates. Parity, speed, and layout fixes on up to 6 templates cost $1,350, and site-wide fixes on up to 12 templates, including m-dot sites, cost $2,050. You get a fixed proposal after a free mobile check.
A mobile SEO audit takes about 1 week for up to 3 templates, including the parity comparison and speed review. Fixes add 1 to 4 weeks, depending on your platform and template count. Google then recrawls the changed pages, and Core Web Vitals field data updates over a rolling 28 days.
It's making sure your site's mobile version is complete, fast, and easy to use, so it ranks well in phone searches. It covers content parity with desktop, mobile speed, layout, and pop-ups. Because Google primarily indexes the mobile version, this work affects how the whole site ranks.
It works by making the version Google indexes, which is mostly the mobile one, as complete and usable as your desktop pages. We compare both versions, restore missing content and markup, then fix speed, pop-ups, and tap targets. Each fix is tested in URL Inspection, which shows the page as Google renders it.
Yes, in focus, though the goal is the same. Regular SEO covers keywords, content, and links. SEO for mobile checks that the phone version carries all of that and works with a thumb on a slow network. With mobile-first indexing, a weak mobile version drags down the whole site.
Yes, a mobile-friendly site helps SEO, but a separate mobile site isn't required. Google recommends responsive design, where one URL serves the same HTML to every device. Mobile site SEO on m-dot setups is possible, but it needs matching content, canonical and alternate tags, and twice the upkeep.
The best fit for your site tests on real phones and compares mobile and desktop versions before suggesting fixes. Ask candidates how they check content parity, which field data they use, and whether fixes go into your theme or a plugin. Be wary of anyone who only sells a higher Lighthouse score.
There's no single official mobile experience score in Google Search. People usually mean the Lighthouse performance score in PageSpeed Insights or the Core Web Vitals status in Search Console. Google retired its Mobile-Friendly Test and Mobile Usability report in 2023, so we report LCP, INP, and CLS from real users instead.
Intrusive pop-ups can hurt mobile search performance when they cover the main content right after a visitor arrives from Google. Small banners, legally required cookie notices, and age checks are treated differently. We replace full-screen pop-ups with banners or delayed prompts that keep the page readable on phones.
Yes, every fix lives in your theme or codebase, and nothing depends on a plugin or service of ours. You get 30 days of fix support after the work, or 60 days on Site-Wide Mobile Fixes. New pages and apps can bring problems back, so we leave a short mobile checklist for your team.
