You wouldn't hire a mechanic who only knows how to rebuild carburetors when your car runs on fuel injection. You'd smile politely, back out of the shop, and find someone who actually works on modern engines.
But that's exactly what happens with web agencies every single day. A business owner hires a shop that's been around since 2012 and assumes longevity equals quality. Sometimes it does. A lot of the time, it means they've been doing the same thing for 13 years and never bothered to learn anything new.
The Web Moved On. Some Agencies Didn't.
The internet in 2012 was a different animal. Most people browsed on desktops. Google ranked pages mostly by keywords and backlinks. Mobile traffic was a fraction of what it is now.
Today, over 60% of web traffic comes from mobile devices. Google uses mobile-first indexing, meaning it judges your site by the phone version first, desktop second. Page speed is a direct ranking factor. And users? They'll bail on a site that takes more than 3 seconds to load. Google's own research backs this up.
The agencies that started building sites in the early 2010s learned one way to do things. The problem isn't that they started there. The problem is that some of them never left.
Red Flags You're Working With an Outdated Agency
Not every established agency is stuck in the past. But here are signs yours might be:
Your site takes forever to load. If your pages take 5+ seconds to appear, something is fundamentally wrong with how the site was built. According to the HTTP Archive, the median page weight has ballooned to over 2.5 MB. A lot of that comes from bloated code, uncompressed images, and frameworks that ship way more than they need to.
It looks terrible on your phone. Not "a little off." Terrible. Text you have to pinch to read, buttons too small to tap, layouts that clearly started as a desktop design and got crammed onto a smaller screen as an afterthought. That's not mobile-friendly. That's desktop with a squeeze.
They can't explain how Google finds you. Ask your agency how your site gets indexed. If they stare at you blankly or mumble something about "meta tags," that's a problem. SEO isn't a bolt-on feature you add at the end. It needs to be part of the foundation, baked into how pages are structured, how content is organized, and how fast everything loads.
They build everything with drag-and-drop page builders. Think of this like building a house with hot glue instead of nails. It holds for a while. It even looks fine from the outside. But the underlying code these tools produce is bloated, slow, and nearly impossible to maintain long-term.
Performance is never part of the conversation. If your agency has never mentioned Core Web Vitals, load times, or Lighthouse scores, they're not measuring anything. They're guessing. And guessing doesn't cut it when Google is literally scoring your site on speed and user experience.
Every small update takes days. You email them to change a phone number. Three days later, it's done. You shouldn't need to file a support ticket to fix a typo on your own website.
What a Modern Approach Actually Looks Like
Here's what you should expect from an agency that's kept up with how the web actually works now:
Speed that you can feel. Pages load in under 2 seconds. Not because of some trick, but because the site was built to be fast from the ground up. Think of it like the difference between a car that was designed to be aerodynamic versus one that has a spoiler bolted on the trunk.
Mobile-first from day one. The site is designed for the phone screen first, then expanded for desktop. Not the other way around. This matters because that's how most of your customers are finding you.
SEO is structural, not decorative. The way the code is written, the way pages link to each other, the way headings and content are organized. All of it should be built with search engines in mind from the start. Not tacked on after the site launches.
You control your own content. Want to update a blog post, change your hours, or add a new service? You should be able to do that yourself, right now, without calling anyone. A modern site gives you a content management system that's actually easy to use.
Performance is measured. Real numbers. Real tools. Your agency should be able to show you exactly how fast your site loads, how Google scores it, and what they're doing to keep improving those numbers.
The Question You Should Be Asking
It's not "how long have you been in business?" It's "how have you changed in the last five years?"
An agency that can't answer that question clearly, with specific examples of new tools they've adopted, new techniques they've learned, new standards they've built into their process, is an agency running on autopilot.
The web doesn't reward autopilot. Your customers notice when a site is slow. Google notices when a site isn't built right. And your competition notices when you're still running a website that feels like it belongs in 2015.
Find an agency that builds for how the web works now, not how it worked when they opened their doors.
