SEO content optimisation

Content that appears in Google search results and is cited by AI. And that convinces your visitors.

You’ve got blogs, product descriptions and landing pages, but they’re not delivering enough results. Your competitor ranks higher than you in Google, and if your customer asks ChatGPT or an AI Overview, your name doesn’t come up. Often, this isn’t down to the amount of content, but to whether that content matches what people are searching for and whether Google and AI models recognise it as a reliable answer.

We analyse your current content, highlight where the opportunities lie and identify what content is still missing. We assess it against Google’s helpful content guidelines and E-E-A-T principles, and ensure that your content is optimised for users, search engines and AI models.

How we work

We don’t start by writing, but by looking at what’s already there and how it works. From this, we draw up a plan that your team can carry out, with us in the background or working alongside you. The five-step process:

  1. Content analysis: We analyse your current content: which pages are performing well, which aren’t, and why. We look at search intent, quality, overlap between pages, and whether the content complies with Google’s helpful content guidelines. We also identify which search queries trigger an AI overview and whether your pages are used as sources in these results.
  2. Search term analysis and content gaps: We identify what your target audience is searching for and what questions they’re asking – including those posed to AI. We then compare this with your current content. This allows you to see which topics are missing, which pages don’t align with the search intent, and where two pages are competing with one another.
  3. Content plan and briefings: We provide a content plan and brief you on the pages. In doing so, we consider search intent, structure, headings, which questions need to be answered, E-E-A-T signals, internal links and metadata. You then get to work on these yourselves; we’ll edit and proofread them if required. If you don’t have the capacity, we can also take care of the implementation.
  4. Reporting and adjustments: We report on organic growth: rankings, clicks, impressions and, where relevant, mentions in AI responses. We do more of what works; we revisit what isn’t performing as well.

Content for Google and AI

Good SEO content has always been content that genuinely answers a question. This is now more important than ever, as AI Overviews, ChatGPT and Gemini build their answers from pages that do exactly that. The same page must therefore be able to do two things: rank in Google and serve as a useful source in an AI response.

That is why we write it like this:

  • The answer is right at the top, not after three paragraphs of build-up
  • Facts, figures and sources rather than vague claims
  • One topic per page, with headings that state the question verbatim
  • An author with demonstrable expertise (E-E-A-T)
  • Structured data where it’s useful (FAQ, product, article)

Windesheim Case Study

Together with the editorial team, we wrote and rewrote 33 pages based on the questions that prospective students actually ask. The pages saw a rise in Google traffic, with 64% more organic clicks and 143% more impressions, and subsequently became a source for dozens of AI Overviews and ChatGPT responses. Read the case study.

What is SEO content?

SEO content is content written for both readers and search engines: texts that cater to the search intent tailored to your target audience and technically well-structured. Think of product descriptions that appeal to customers and Google, blog articles that answer your target audience’s questions, and landing pages designed for specific search terms.

The big advantage is that a good article continues to perform well for months or even years. As a result, SEO content delivers more sustainable results than adverts, which stop as soon as your budget runs out.

What we look out for

These are the factors that determine whether a text is successful. Would you like to give it a go yourself? Then read Writing for SEO: the HUMMSTAL method.

  • Search term and intent: looking for information, comparing options or making a purchase? The text is tailored to what the searcher wants.
  • Structure: clear headings, short paragraphs, easy to scan.
  • Writing for the reader: active, clear, without keyword stuffing.
  • SEO elements: meta title and description, alt-texts, internal links.
  • Enrichment: images, tables, videos and FAQs that provide a better answer to the question.

Frequently asked questions

Usually not. We analyse, draw up the plan and provide page-by-page briefings: your team writes and we edit. That way, your product knowledge or expertise remains in-house. If you don’t have the capacity, we can also take care of the writing, and you can then check that the content is accurate.

Google assesses whether content is genuinely written to help the visitor (helpful content) and whether the source demonstrates experience, expertise, authority and trustworthiness (E-E-A-T). Pages that do not meet these criteria score poorly and are not used as sources by AI models. That is why these are the guiding principles of our content analysis.

That’s the aim. Content that answers a question directly, with facts, sources and a recognisable author, is exactly what AI models use. Do you want to measure that and steer your strategy accordingly? Then we’ll combine it with GEO.

We provide the analysis, the plan and the briefings. You write the content; we review it before publication and make adjustments based on the results. You can combine this with a writing workshop for SEO.

Usually within three to six months, depending on the level of competition and your website’s authority. Rewritten existing pages often rank more quickly than new ones.

Algemeen Directeur

Onder helps us with our organic search visibility, both via SEO and via GEO. They look at how we can maintain our visibility in search engines using Kitcentrum and, increasingly, in AI-generated answers as well. They have already demonstrated their capabilities during previous changes to our URL structure. We did not lose any rankings and, in fact, saw our visibility improve. That gives us confidence. Now, Onder is helping us prepare for our replatforming. We are fully confident that they will guide us effectively through this transition and manage to retain our organic rankings as much as possible.

Marten Stellingwerf

Webmaster

Martijn and Mariska make the SEO story understandable for the layman and are happy to think along with us. It is nice that there is a personal contact moment every month with an extensive report and the opportunity to discuss everything. After just a few months, Onder has already managed to achieve number 1 positions on Google with some of our webshop pages. We are very satisfied with Onder.
