Every agency you've ever talked to says "SEO included." It's right there on the proposal, usually near the bottom, like a little bonus they're throwing in. Sounds great, right? Free SEO with your new website.
Here's the thing. What most agencies mean by "SEO" and what actually moves the needle for your business are two very different things. And that gap is costing you real money.
What Most Agencies Actually Do
When a typical agency says they'll handle your SEO, here's what that usually looks like in practice:
- They install a plugin like Yoast on your WordPress site. That's a tool, not a strategy. It's like buying a gym membership and never showing up.
- Someone writes a meta description for the homepage. Just the homepage. The other 15 pages on your site? Blank.
- Keywords get sprinkled into random paragraphs with no real plan behind where they go or why.
- Maybe, if you're lucky, they submit your site to Google once and never touch it again.
That's it. That's "SEO included."
And look, some of these agencies aren't trying to rip you off. They just don't have the knowledge or the time to do it right. SEO is a whole discipline. Tacking it onto a web build as an afterthought is like asking your plumber to also rewire your electrical panel while he's there.
What Real SEO Actually Looks Like
Real technical SEO is a checklist of about a dozen things that all have to work together. Miss one and the whole thing underperforms. Here's what should actually happen when someone says SEO is part of the build.
Every single page gets its own title and meta description. Not just the homepage. Every page. Google uses these to decide what your page is about and how to display it in search results. If they're missing, Google just guesses. You don't want Google guessing.
URLs are clean and readable. Your pricing page should live at /pricing, not /page?id=47392. Clean URLs tell both humans and search engines what's on the page before they even click. Google's own documentation recommends simple, descriptive URLs.
Headings follow a real hierarchy. H1, H2, H3 — they're not just font sizes. They tell Google how your content is organized, like chapters and sections in a book. When agencies just pick heading sizes based on what "looks good," the structure turns into noise.
Images are the right size and have alt text. A 4MB photo that takes six seconds to load will tank your page speed. And if the image doesn't have alt text describing what's in it, Google can't "see" it at all. Web.dev's image guide breaks this down well.
The site loads fast. Google has said plainly that page speed is a ranking factor. If your site takes four seconds to load on a phone, you're getting penalized before your content even gets evaluated.
It works on mobile first. Google uses mobile-first indexing, meaning it looks at the mobile version of your site before the desktop version. If your site is janky on a phone, that's what Google judges you on.
An XML sitemap gets submitted to Google Search Console. Think of a sitemap like handing Google a table of contents for your entire site. Without it, Google has to wander around and find pages on its own. With it, you're saying "here's everything, go index it." Google recommends this for every site.
Structured data tells Google what things are. This is the one almost nobody does. Structured data (also called schema markup) is code that tells Google "this is a business," "this is a service," "this is an FAQ." It's how you get those rich results in search — star ratings, FAQ dropdowns, business info panels.
Internal links connect your pages with purpose. Every page on your site should link to other relevant pages. It helps visitors find what they need, and it helps Google understand the relationship between your content. Moz's beginner guide covers why this matters.
Someone actually monitors it after launch. SEO isn't a set-it-and-forget-it thing. Search algorithms change. Competitors publish new content. Pages break. If nobody's watching your Google Search Console data and making adjustments, you're slowly falling behind without knowing it.
The Car Wash Analogy
Think about it this way. "SEO included" at most agencies is like a car wash that sprays your car with a garden hose and calls it a full detail. Sure, technically they washed your car. But a real detail means the engine bay, the tires, the interior, clay bar, wax, the works.
Both places say "car wash." Only one of them actually does the job.
That's the difference between an agency that installs a plugin and one that builds your site with search in mind from day one.
How to Protect Yourself
Next time an agency tells you SEO is included, ask them to be specific. What pages get meta descriptions? Will there be structured data? Are you submitting a sitemap to Search Console? Who monitors performance after launch?
If they can't answer those questions, they're handing you a garden hose.
Real SEO isn't a feature you bolt on. It's how the site gets built in the first place.
