The Technical Web Guide for Marketers: What Every Marketer Should Know About Domains, Email, Tracking, Search and AI (New Book)
A plain-language book for marketers who work with websites every day: domains and DNS, email deliverability, tracking and attribution, technical SEO and AI search. What's inside and who it is for.

For more than fifteen years I have been on the technical side of websites: building OpenCart stores, fixing email that wouldn’t send, setting up tracking, cleaning up after website migrations. Over that time I saw the same thing happen again and again. A marketing team plans a good campaign, and something technical that nobody owned breaks it.
The domain expires because the renewal card was a former employee’s. The launch email goes to spam because the new email platform was never authenticated. The ads report 200 conversions and analytics shows 90, and nobody can explain why. The redesigned website goes live and organic traffic halves in a month.
None of these need a marketer to become a developer. They need a marketer who knows enough to ask the right question at the right time. That is why I wrote The Technical Web Guide for Marketers: What Every Marketer Should Know About Domains, Email, Tracking, Search and AI.
Who the book is for
- Marketing managers and generalists who own the website, the email platform and the analytics account, often without a developer on the team.
- Marketing operations and email specialists who are asked to “just add a DNS record” and want to know what that record does.
- Founders and small business owners who do their own marketing and want to stop guessing.
- Agency teams who inherit client websites and need a quick way to check what is set up and what isn’t.
You don’t need to know how to code. When a term like DNS, DKIM, canonical tag or server-side tagging appears, the book explains what it is, why a marketer should care, and what to ask your developer, hosting company or agency.
What it covers
| Area | The questions it answers |
|---|---|
| Domains | Who really owns our domain? What happens if it expires? What does DNS do, and what breaks when someone changes it? |
| Why do our emails land in spam? What are SPF, DKIM and DMARC? What do Gmail, Yahoo and Microsoft now require from bulk senders? | |
| Tracking | How do UTMs, cookies, pixels and consent fit together? Why don’t analytics and ad platform numbers match? |
| Search | What technical problems stop good content from ranking? How do we redesign or migrate a website without losing traffic? |
| AI | How do AI assistants and AI search find and use our content? Which crawlers can we allow or block, and what does that change? |
Why marketers need this now
The technical side of marketing used to be something you could leave to IT. That changed over the last few years:
- Gmail, Yahoo and Microsoft now require authentication from anyone sending email in volume. Getting it wrong is no longer a small dip in open rates. Your email gets junked or rejected.
- Privacy laws, consent banners and browser restrictions mean tracking is incomplete by default. Marketers who understand why can still make good decisions with the data.
- Search results now include AI answers, and people ask ChatGPT, Gemini, Claude and Perplexity before they ever visit a website. Whether your content can be read and cited is partly a technical question.
