The most expensive mistake in SEO isn’t bad copy or a shortage of links. It’s a site that was built first and only then thought about SEO. We’ve seen dozens of projects where the client spent hundreds of thousands of hryvnias on development, got a beautiful site — and a month after launch learned it had to be rebuilt. The URL structure is wrong, the needed pages don’t exist, the technical side won’t let the catalog be indexed, the content is written ‘for people’ with no connection to queries.
Preparing a site for launch with SEO in mind is a separate service that saves you budget for years ahead. Instead of building the site twice (first however it turns out, then how it should be), you build it once and right from the start.
What usually goes wrong after a ‘normal’ launch
- An illogical URL structure — links like /page-32, /service-1, /catalog/?id=15. A year later you’ll have to do mass redirects and lose some link equity.
- No landing pages for key query clusters — there’s a ‘services’ category but no separate pages for ‘landing page development’, ‘online store development’, ‘corporate site’.
- Duplicate content — identical text on different URLs, parameter variants, print versions without canonical.
- No schema markup — Google doesn’t understand that this is a product, review, FAQ or service. AI search ignores such pages entirely.
- Important pages that can’t be indexed — blocked in robots.txt ‘just in case’, noindex on categories, wrong canonicals.
- Release on a test domain with open indexing — Google manages to bake in duplicates before the official launch.
What we do BEFORE launch
We build the full semantic core. Based on it we design the site structure — a map with all landing pages, hierarchy and internal linking. We agree the URL logic with the developers: clean URLs, no duplicates, correct handling of pagination and filters.
We prepare detailed specs for each page — H1, Title, Description, required subheadings, keywords and LSI terms, recommended length. We hand them to copywriters or your content team.
During the design stage we check the mockups for typical SEO mistakes: a missing H1, headings as images instead of text, unclear CTAs, illogical content structure. During the build stage we make sure meta tags, schema and OpenGraph are implemented correctly.
A special case — migrating an existing site
If you’re rebuilding a site that already works, the risk of losing traffic is at its highest. Changing the URL structure without redirects means -60 / -80% organic traffic in the very first week. We prepare a detailed redirect map from old URLs to new ones, test it on a staging environment, and measure rankings before and after release. In 95% of our migrations we don’t lose traffic — on the contrary, we gain by fixing accumulated errors.
Launch-day checklist
Right before launch we go through a 120-item checklist. Among them are dozens that are usually forgotten:
- robots.txt is open for indexing;
- noindex removed from the test environment;
- sitemap.xml created and submitted to GSC;
- all canonicals checked;
- schema.org validates;
- OG tags configured;
- analytics and GSC connected;
- 404 pages return the correct code;
- HTTPS set up with no mixed content;
- load speed in the green zone of Core Web Vitals.
Miss any of these and you start with problems that then take months to fix. Better to spend 2–4 weeks on preparation than 6 months on fixes.
