The usual order is: build the site, launch it, then hire someone to “do the SEO.” It sounds sensible. It’s backwards, and it’s the reason so much SEO work turns out to be expensive.
What gets decided during the build
Much of what determines whether a site can rank isn’t the writing. It’s the structure. And structure gets locked in early:
- How fast pages load, which comes mostly from how the site is built rather than what’s written on it.
- Whether each page has its own address and a clear reason to exist, or whether the whole site is one long scroll with nothing separate to point at.
- How pages link to one another, which is how search engines work out which of them matter.
- Whether the site is labeled behind the scenes, so search engines and AI models can tell what you do and where you do it.
None of that is content work. All of it is build work. Once the site exists, changing any of it means taking parts of it apart again.
Adding SEO to a finished site is renovation. Building it in is just construction.
The version that costs real money
Here’s how it usually goes wrong. A business gets a genuinely beautiful site where every section is one long scroll and the entire thing lives at a single address. It photographs well. There is nothing for a search engine to rank except the front door.
Fixing that isn’t a monthly SEO retainer. It’s a rebuild, and it tends to get sold as one about a year later, to the same business, for the second time.
And now there’s a second reader
There’s a newer reason this matters. AI models read your site too, and they’re less patient than search engines are. A search engine will make an educated guess about a badly structured page. A model putting together a recommendation will skip it and use a competitor’s page that was easier to read. That’s a different job again, and it’s the one behind why ChatGPT might not be recommending you.
Same fix. Twice the reason to do it up front.
What to ask before a build starts
Three questions, and you don’t need to be technical to ask any of them:
- Does every page I care about have its own address?
- How fast will this load on a phone, on mobile data, not office wifi?
- Is the site labeled so search engines and AI models can tell what we do?
If the answers come back vague, the SEO invoice is already being written. You just haven’t received it yet. Worth knowing what a build should cost before you have that conversation: what a website actually costs.
