Technical SEO consulting

Technical SEO consultant for sites that need fixes in production, not another content calendar.

I work as a technical SEO consultant on crawlability, indexation, site architecture, schema, and the SEO risk inside a website redesign. SEO consulting here is implementation-heavy. If you need 40 blog posts a month, that is a different hire.

What you get

What changes when this is done right.

Three outcomes I hold myself to before anything ships. If these are not the job, this is the wrong page.

01

A crawlable, indexable site

The SEO consulting starts with the technical base: crawl paths, indexation, canonical logic, and the structure search engines actually reward.

02

Migrations without the drop

Replatforming or redesigning is where most sites lose rankings. I map redirects and protect the URLs that already earn traffic.

03

Fixes that ship, not a PDF

An SEO consultant who also builds sites means recommendations get implemented, not filed. I stay in the room during the build.

The engagement

What this work actually covers.

Scope first, so you know what you are buying and what stays out.

What SEO consulting covers here

Technical SEO audits, SEO migrations, website optimization, and the structured data a worthwhile site actually needs. I also stay in the room when the redesign or website development starts, so recommendations do not die in a PDF.

When this is the right hire

You are replatforming, the site dropped after a launch, or Search Console is noisy and nobody owns it. An SEO consultant who also builds websites is useful there. A generic SEO agency pitching guest posts is not.

What I will not sell you

Guaranteed rankings, private blog networks, or a 200-keyword list with no page to put them on. The work is the site, the architecture, and the pages that can rank.

What SEO consulting services include

SEO consulting services here cover a technical SEO audit, crawlability and indexation fixes, architecture and internal linking, schema, redirect mapping for redesigns, and Search Console after the work ships. An SEO optimization consultant who also builds sites means those fixes get implemented, not filed.

Freelance SEO consultant versus an SEO agency

A freelance SEO consultant is one person in the codebase and in Search Console. An agency often sells a content calendar and a junior on the account. If you need a technical SEO consultant for a migration, a leaky site, or a website redesign, the freelance model is usually the better fit. Local SEO consultant work can sit next to that when the business actually needs local visibility.

Local SEO and the map pack

Map pack work is a subsection of technical SEO consulting, not a separate MedSpa retainer. Categories, NAP consistency, Google Business photos, and a site that matches the listing come before more city pages. Clinic articles on this site are lead-ins to that work and to website redesign.

How it works

A sequence, not a scramble.

Same order every time. Discovery, the plan, the build, then the check after launch.

  1. Technical SEO audit

    A full crawl of the site: indexation, architecture, speed, schema, and the issues quietly leaking rankings. You get a prioritized list, not a data dump.

    Days 1-5

    Prioritized issue list

  2. Fix the base

    Crawlability, canonicals, internal links, titles, and structured data get fixed first, because content cannot outrun a broken foundation.

    Week 2

    Crawl, canonical, and schema fixes

  3. Protect during changes

    If a redesign or migration is coming, I map redirects and guard the URLs that already rank so nothing is lost at launch.

    During the build

    Redirect map ready before go-live

  4. Measure and iterate

    I watch Search Console after changes, confirm what moved, and tighten the pages that are close to ranking.

    30 days after

    Search Console report and next fixes

Zlatko is a PRO! Something I was struggling with for months, took him only a few days.

What is included

What lands on your side.

The artifacts you keep after the call, the build, or the audit.

Technical SEO audit

A crawl of the site with a ranked list of what to fix first, not a 90-page PDF dump.

Crawlability and indexation fixes

Canonicals, robots, sitemaps, and the pages that should be in the index but are not.

Architecture and internal linking

A structure search engines can crawl and visitors can follow to the pages that should rank.

Schema and structured data

The markup a worthwhile site actually needs: Organization, WebPage, FAQ, Article, Service.

Redirect mapping

URL-level mapping for redesigns and migrations so rankings do not walk off a cliff at launch.

Search Console monitoring

A watch after the work ships, with a short report on what moved and what still needs a pass.

Before we start

Questions about this work.

Short answers so you can tell if this is the right engagement.

Technical SEO is the core. I also fix titles, internal links, and page purpose when that is what is blocking the query. I do not run a separate content mill.

Yes. Some companies want the audit only. Others keep an SEO consultant through the website redesign and the first months after launch.

Technical fixes can show up in weeks. Rankings on competitive terms take longer. I will tell you what should move first and what is a longer play. I do not sell guaranteed rankings.

No. Anyone who does is selling you something they cannot control. I fix the site, the architecture, and the pages that can rank, then we measure in Search Console.

Sitewide technical SEO is the default: crawlability, indexation, architecture, schema, and migrations. Local SEO can sit next to that when the business actually needs it.

Yes. That is one of the highest-value times to hire an SEO consultant. I map redirects and protect the URLs that already earn traffic before anything launches.

A crawl of the site, indexation and canonical issues, architecture, internal links, titles, schema, and a prioritized list of what to fix first. Not a 90-page PDF dump.

If the technical base is broken, more posts will not save it. Once the site can be crawled and the pages have a job, content helps. I will tell you which problem you actually have.

Freelance. You work with me on the audit, the fixes, and the migration. SEO consulting services are not handed to a junior after the sales call.

A technical SEO audit, crawl and indexation fixes, architecture and internal linking, schema, redirect mapping when a redesign is in play, and Search Console monitoring after the work ships.

Related services

Other ways I can help.

Same person, same commercial standard. Different entry point.

01
Digital strategy

Digital strategy consultant for companies that need a digital strategist, not a workshop deck.

Most teams do not need another workshop deck. They need a digital strategist who can say what the site is for, what to build first, and what can wait. I do digital strategy consulting that stays connected to design and website development, so the plan does not die in a PDF.

02
Website redesign

Website redesign services that protect SEO and give the site a commercial job.

A redesign fails when it starts in Figma. Website redesign services should start with website strategy, the pages that create pipeline, then website design and website development. I run that sequence so a custom website redesign does not erase the rankings you already have.

03
CRO

Conversion rate optimization consultant for sites that get traffic and still miss the sale.

Conversion rate optimization consultant work starts with the offer and the page job, then I change the page. If the offer is unclear or the website redesign never defined a job for each URL, tests will not save it.

View
04
AI application development

AI application development for teams that need a product in production, not another demo.

Most Lovable, Bolt, and v0 apps stall after the prototype. You need someone who can take the idea from prompt to production: structured outputs, auth, billing, logging, cost controls, and a codebase your team can maintain.

05
White-label web development

White-label web development for agencies that need senior delivery without another full-time hire.

Your client signed, the internal bench is full, and the deadline did not move. I handle white-label Next.js and Webflow delivery under your agency's brand, including a trial task, clear ownership, and code your team can keep.
