Pricing questions
Is the €449 setup fee really all-inclusive?
Yes. The €449 covers building the full 5-page website, all AEO configuration (schema, llms.txt, sitemap) and going live. The Pro plan includes AI chatbot setup too. After that, you only pay the monthly fee.
What is the difference between Essential (€79) and Pro (€149)?
Essential gives you everything to get found by ChatGPT and Google: hosting, 4 new pages per month and full AEO setup. Pro adds an AI chatbot that answers customer questions 24/7, qualifies leads and handles quote requests — including nights and weekends.
Can I upgrade from Essential to Pro later?
Yes, at any time. You can switch to the Pro plan whenever you want. The chatbot will be set up and trained on your business within a week.
What exactly are the 4 new pages per month?
Every month we write and publish 4 new pages on your site: about current subsidies, comparisons, regulations or local relevance. These pages get found by ChatGPT and Google. You can order more pages via the calculator.
Can I cancel at any time?
Yes, monthly cancellable with no penalties. Your site and all content remain yours. Only the monthly maintenance and new pages stop.
How do I know what Sieng did for me each month?
At the end of every month you receive a clear PDF report by email. It includes: which articles were published (with links), how your AI visibility score changed in ChatGPT and Perplexity, which technical improvements were made, and an overview of all Google indexing submissions. The same report is also available in your client portal.
Do you work with businesses outside the installer industry?
Currently we focus exclusively on solar panel, heat pump, and insulation installers in NL and BE. This focus means we know the subsidies, customer questions, and content that works — delivering better results than a generalist.
