Tech SEO Agency

Tech SEO agency for sites where the crawler is the bottleneck. INTSEO Media is built around one job: finding the technical reasons a site underperforms in search, then working with your engineers until the fix is live. Crawl budget, indexation, JavaScript rendering, migrations, Core Web Vitals, structured data. The unglamorous work that decides how much of your content Google can actually see.

The problem

Technical SEO is where most sites quietly lose

A page gets crawled and never indexed. A replatform drops 40% of organic traffic on launch day and nobody catches it for a week. A JavaScript framework renders fine for users and poorly for Googlebot, so half the catalogue is invisible in search. An agency delivers a 90-page audit and the file sits in a shared drive, unread, while rankings slide.

None of that shows up in a content brief or a keyword report. It hides in log files, in the rendered DOM, in redirect chains left behind by three past migrations, in a robots.txt rule someone added in 2019. The site looks healthy from the outside and leaks traffic from the inside.

The uncomfortable truth is that most technical SEO problems are organisational, not technical. The fix is usually known within a week. It ships six months later because it sits behind a dev backlog with no owner. Closing that gap is the real job of a tech SEO agency, and it is what our team optimises for.

How we work

What working with a tech SEO agency should feel like

The audit is the easy part. The difference is whether the findings turn into shipped code. Our process is built around that handover.

01

Discovery and access setup

We get read access to Search Console, Bing Webmaster Tools, analytics, and server or CDN logs, plus staging for anything pre-launch. We map the templates, the URL patterns, and the platform constraints before touching a crawler.

02

Crawl and log analysis

We crawl the site with Screaming Frog or Sitebulb, cross-reference the Search Console Pages report, and read the server log data to see what Googlebot actually requests and how often. Log files are where crawl waste and orphan pages stop being theoretical.

03

Prioritised findings, scored honestly

Every issue gets a score for likely impact and for implementation effort. A high-impact, low-effort fix goes to the top. A 90-page list of everything technically imperfect helps nobody, so you get a ranked register instead.

04

Implementation with your engineers

We write each fix as a ticket with reproduction steps, acceptance criteria, and a verification plan. On modern stacks we can open pull requests directly. This is the step most audits skip, and it is the step that decides whether anything changes.

05

Verification after deploy

Once a fix ships we confirm it in the field: rendered HTML, index status, redirect behaviour, Core Web Vitals from real users. If it did not move what we said it would, we reopen it. Nothing gets marked done on a promise.

Field reference

Where technical SEO breaks most often

A working reference we use on nearly every engagement. Match the symptom to the likely cause, confirm it in the right place, then ship the fix.

This is a starting point, not a diagnosis. The same symptom can have three different causes on three different stacks, which is exactly why a real audit reads your logs instead of guessing.

Platforms and stacks

We work where your site already lives

We do not push a preferred CMS. We meet the platform you have, with its real constraints, and we know where each one tends to cause trouble.

Stacks

  • Next.js & React
  • Shopify & Shopify Plus
  • WordPress & headless WordPress
  • Webflow
  • Adobe Experience Manager
  • Sitecore
  • Custom & in-house stacks

Site types

  • Large ecommerce catalogues
  • Marketplaces
  • Publishers & media
  • SaaS products
  • Multi-region enterprise sites

A headless WordPress build breaks differently from Shopify Plus, which breaks differently again from Adobe Experience Manager. Knowing the platform means we spend the first week finding problems instead of learning the CMS. That fluency is a large part of what you actually hire a tech SEO agency for.

Guardrails

What we will not do

A short list, and the reason each one fails. This is usually where you can tell a specialist technical SEO agency apart from a reseller.

90-page audit PDFs with no prioritisation

A document that lists every imperfection without ranking it by impact is a way to look thorough while shipping nothing. Your team cannot act on 400 undifferentiated line items, so they act on none.

Tool exports rebranded as an audit

A raw crawl export or a PageSpeed screenshot is not analysis. Anyone can run the tool. The value is in reading the output against your logs, your architecture, and your business, then deciding what actually matters.

Recommendations we cannot explain to an engineer

If we cannot describe why a change works and how to verify it, a good developer will push back, and they should. Every recommendation comes with the reasoning and the test, so it survives code review.

Ranking guarantees

Nobody controls Google's ranking systems, and anyone promising a position is either naive or dishonest. We commit to the technical work and to measurable changes in crawl, index coverage, and Core Web Vitals, which is what we can actually influence.

Work we cannot verify after deploy

If a fix cannot be confirmed in logs, in the rendered DOM, in Search Console, or in field data, we treat it as unfinished. Verification is the difference between advice and results.

Positioning

Why teams choose a specialist technical SEO agency

Generalist agencies are good at content and links and campaigns. That work matters. But it assumes the site underneath it can be crawled, rendered, and indexed cleanly, and on large or complex sites that assumption is often wrong. A specialist technical SEO agency starts from the infrastructure and works up.

The value of a technical SEO agency is not a longer list of issues. It is judgement about which issues matter, on your stack, at your scale, and the ability to sit with your engineers and get the fix merged. That is the part that is genuinely hard to buy, and it is what we do all day.

A tech SEO agency worth hiring also keeps the scope honest. If your real constraint is content strategy rather than crawling, we will tell you, because a perfect crawl of pages nobody wants to read does not move revenue.

FAQ

Questions buyers actually ask

How long does a technical SEO audit take?

For most sites, two to three weeks from the point we have access. A large ecommerce catalogue or a multi-region enterprise site with millions of URLs takes longer, mostly because crawling and log analysis at that scale is slow. We scope the timeline before we start so there are no surprises. The audit is not the slow part. Implementation is.

Do you work with our in-house developers, or around them?

With them, always. We write findings as engineering tickets with acceptance criteria, not as a PDF thrown over the wall. That means reproduction steps, the expected behaviour, and how we will verify the fix after deploy. Most of our value shows up in that handover, because the audit is easy and the shipping is hard.

Can you work directly in our repo?

Often, yes. For Next.js, React, and other modern stacks we can open pull requests for rendering, metadata, sitemap, and structured data changes, then let your team review and merge. On locked-down enterprise setups we stay in tickets and pairing sessions instead. We adapt to how your engineering org actually works.

What access do you need to get started?

Read access to Google Search Console and Bing Webmaster Tools, analytics, and ideally server log files or CDN logs. For migrations we also want staging access before launch. If log files are hard to get, we can start without them, but say up front that log data is where the most useful findings tend to hide on large sites.

How do you handle a migration that has already gone wrong?

First we stop the bleeding. We crawl the old and new URL sets, find the broken and chained redirects, check for lost canonicals and noindex tags shipped by accident, and confirm what Google has already dropped from the index. Then we sequence the recovery by traffic impact so the highest-value URLs get fixed first. Recovery is usually possible. It is faster the sooner we look.

Do you just hand over a spreadsheet and leave?

No. A findings register is one deliverable, not the engagement. We stay through implementation, answer developer questions, review the changes on staging, and run a verification pass after deploy to confirm the fix did what we said it would. Work we cannot verify after it ships is work we will not put our name on.

What if our dev team never implements the recommendations?

This is the real failure mode in technical SEO, and it is usually organisational rather than technical. We fight it by scoring every finding on impact and implementation effort, keeping the priority list short, writing tickets a developer can pick up without a meeting, and reporting on what shipped rather than what was recommended. We can also present directly to engineering leadership to get the work onto a sprint.

How do you report on the work?

A living findings register your team can see, plus a short written update at agreed intervals tied to what changed and what moved. We pull field data from the Chrome UX Report and Search Console rather than vanity lab scores. For large accounts we can wire Search Console and log data into BigQuery and Looker Studio so you watch crawl and index trends over time.

How long is a typical engagement?

It varies. A standalone technical SEO audit is a fixed piece of work. A migration runs from pre-launch planning through post-launch monitoring, usually two to four months. Ongoing technical SEO for a large site is a retained relationship, because crawl, index, and rendering issues keep appearing as the site and its templates change. We will recommend the smallest engagement that solves your actual problem.

How does scoping and quoting work?

We do not publish pricing, and honestly no tech SEO agency can quote fairly without seeing the site, because the number depends on scale, stack, log availability, and how much implementation support you need. The first call is scoping. We look at the site, ask about access and constraints, and follow up with a written proposal and a custom quote. No packages, no anchored price on the site to work backwards from.
