"We'll do SEO later" is a sentence that usually means paying for it twice. Part of what SEO covers is content, and that really can be added for years. The other part is the structure of the site, and that's hard and expensive to change later.
This post separates the two.
What gets built in, not added
URL structure
A page's address is decided at the start and is expensive to change. Every change needs a redirect, and a chain of redirects dilutes what the page has built up.
/services/custom-websites and /page?id=42 aren't the same thing, for a person or for a search engine.
How many pages there are
This is the biggest single decision and the one most often missed.
One page listing five services ranks for none of them, because it isn't about any of them. Five separate pages rank for five terms.
Splitting one page into five afterwards means new content, new addresses and redirects: work that was free at the start.
Heading hierarchy
Headings are the frame a search engine reads the page by. When an h3 is used because it's smaller, not because it's a subheading, that frame disappears.
Fixing it on a finished site often means touching every component.
Languages
If the site will ever have a second language, the structure is set up straight away, even while there's only one. Adding it later means changing every address.
Speed
Speed isn't added. It's a consequence of how the site is built: how much code is sent, how it's served, how the images are prepared. The details are in what makes a website fast.
On a finished site you can fix images and scripts. The amount of code a platform sends, you can't.
Structured data
The data that tells Google who you are, what you offer and at what price. It's added relatively easily, but it needs the content to exist in a form that can be described, and that's a matter of structure.
What really can be added later
To be fair, because the opposite gets exaggerated too:
- Content. Texts, pages, answers to questions. This work never stops, and it's normal for it to start after launch.
- Links from other sites. They're built over years.
- Google Business Profile.
- Refining titles and descriptions based on what Search Console shows.
So it's fair to say: SEO isn't a one-off service. But the foundation is laid once.
What it costs to fix later
Roughly, from practice:
- Titles and descriptions: small, a few hours.
- Structured data: a day or two.
- Heading hierarchy: depends on how the site is built; from a few hours to reworking every component.
- Splitting one page into five: new content and redirects.
- Changing the URL structure: a job that touches the whole site.
- Adding a second language afterwards: often close to a new build.
The same list, done at the start, adds almost nothing to the project. The difference isn't in the effort but in the timing.
So why isn't it always done
Three common reasons:
It's sold separately. SEO as a monthly service is a better business than SEO as part of the build.
People don't know. Some developers do what they've seen done, not what's been checked.
The client doesn't ask. If it isn't in the quote, it usually isn't done either.
The question that settles it: "Which parts of SEO are included in the build, and which are separate?" The answer shows who you're talking to.
What to look for in a quote
That the build includes at least:
- A separate page per service.
- A title and meta description for every page.
- Correct heading hierarchy.
- Clean addresses.
sitemap.xmlandrobots.txt.- Structured data for the business and services.
- Search Console and analytics set up.
- Speed checked on mobile.
That isn't an extra service. That's building a website properly.
Frequently asked questions
Does that mean I don't need an SEO service afterwards?
It depends on the market. The foundation and basic content are enough for local queries and your own name. Competitive queries need content written regularly.
How much does it add to the cost of the build?
With me it doesn't: it's part of the build. Elsewhere, ask, because it's often charged separately.
I have a finished site. Is it too late?
No. Some of it is cheap to fix, some isn't. The checklist is in an SEO checklist for launch.
How long until it shows?
Three to six months for a new site.
