Full SEO support
throughout development

We work alongside your development team — or take full ownership of the technical SEO from brief to launch.

SEO Audit of Technical Brief

We review the technical specification before development begins — identifying SEO risks in the site structure, URL scheme, multilingual setup, and technical decisions before they become problems.

Proper URL Architecture

We design a URL hierarchy that is intuitive for both search engines and users. Slugs, categories, filters — no cannibalisation or duplicate content from the very start.

Performance Optimisation (Core Web Vitals)

LCP, CLS, INP — we take responsibility for performance metrics at the architectural level: lazy-load, critical CSS, font optimisation, image compression.

Keyword Mapping Before Launch

We research and cluster keywords before the site goes live — so every page is indexed for the right search terms from day one.

Technical SEO Markup

We implement Schema.org, hreflang, canonical, Open Graph, and structured data — in code, not plugins, giving precise control over every markup element.

Internal Linking Structure

We design internal link architecture as part of the overall site structure — so search engines understand page priorities and PageRank flows correctly.

5 stages of SEO
during development

Running in parallel with your development team — at every sprint we review and close SEO tasks together.

01
SEO Brief Analysis

We review the technical specification: structure, URLs, CMS, functionality — identifying SEO conflicts before development starts.

02
Semantics & Structure

We research keywords, design the page hierarchy and URL scheme aligned with actual search demand.

03
Technical Implementation

Together with developers we implement markup: Schema, hreflang, canonical, meta tags, and performance optimisation.

04
Pre-Launch Review

Pre-launch audit: crawler scan, verification of all technical elements, GSC setup, sitemap, robots.txt.

05
Post-Launch Monitoring

We track indexation, early rankings, and technical health — adjusting strategy based on real data.

Technologies We Use
in Our Work

Every decision is backed by data from proven tools — not guesswork.

Claude Code
AI-powered development assistant

We automate the generation of SEO markup, Schema.org, hreflang, and technical recommendations — Claude Code helps us accelerate routine work without sacrificing quality.

Serpstat
Semantics & audit

We collect semantic cores, analyze competitors, track positions, and run technical SEO audits on new pages before they go live.

Ahrefs
Backlink analysis

We analyze link profiles, competitive search results, and content gaps. We use it to build internal linking strategies for new sites.

Screaming Frog
Technical audit & crawling

We audit the technical SEO structure in staging: duplicate titles, missing meta, broken links, canonical and hreflang issues — before going to production.

Cases: SEO

What happens when
SEO is ignored
during development

Architecture-level mistakes cost far more to fix than to prevent from the start.

01
Costly Redesign & Migration

Changing URL structure or CMS after indexation always risks ranking losses. A properly handled migration with SEO support costs 3–5× more than building the right architecture from the start.

02
Slow Organic Traffic Growth

A site without a technical foundation enters search engines twice as slowly. Every month without organic traffic means direct budget losses as you rely on paid channels to cover demand.

03
Technical Debt That Never Resolves

Duplicate pages, missing canonical tags, incorrect hreflang — these aren’t problems you can patch with a plugin. They require template rework and significant developer time.

04
Losing Ground to Competitors

While you’re reworking the technical foundation, competitors are claiming positions in search results. One month of technical debt means at least 3–4 months of catch-up in the SERPs.

Frequently asked questions
about SEO during development

Ideally — during the technical brief stage, before development begins. The minimum acceptable point is during development, in parallel with the first sprints. Involving SEO only after launch leads to inefficient spending on technical rework.
Yes, absolutely. We analyse the current state of development, identify critical SEO elements, and provide technical requirements to the developers. Some tasks can be implemented before launch, others immediately after go-live.
From an SEO perspective, the CMS matters less than the quality of implementation. WordPress, Webflow, Next.js, Shopify — all can deliver technically sound SEO with the right approach. We provide CMS recommendations based on your business type and SEO objectives.
Absolutely. Preparing keyword mapping, URL structure, meta tags, and technical markup before launch allows the site to enter the index correctly from day one. This reduces time to first organic traffic by 2–3×.
Performance is a key SEO factor. We monitor Core Web Vitals throughout development: image format selection, critical CSS, deferred script loading, CDN setup. This is significantly cheaper than optimising an already-built site.
The migration SEO plan includes: preserving all URLs and setting up 301 redirects, migrating meta tags and structured data, updating sitemap and canonical tags, and post-migration monitoring via Google Search Console. We ensure the site retains its rankings during the move.

You can do this
yourself.
But with us — faster.

SEO during development isn’t magic. There’s a clear workflow: semantics, architecture, markup, audit. If you have an in-house SEO specialist and time — you can go through all these steps on your own.

We’ve documented the full process in our guide. Read it through — and if you feel like delegating even part of it, we’re here.

Founder’s View

SEO is an endless process that must pay off. Algorithms change, competition grows, new search formats (AI Overviews, SGE) rewrite the rules. That’s why the most important thing is to have a transparent partner who doesn’t just “do SEO” but constantly tracks changes and adapts the strategy to current best practices. An agency using methods from 3 years ago is costing you money — not earning it.
