About the author

I have been building, breaking, and fixing websites since 1999. The day job is Yeseo, an SEO and AI consultancy I founded and still run, working with clients on search visibility, AI workflow, and the kind of small operational decisions that compound over years. Twenty-five-odd years in, the work has shifted from raw search engine work to something broader: search, AI cost modelling, content strategy, and the bits of small-business technology that nobody else fancies explaining.

WebCaretakers is the personal project. It is where I make small, focused calculators for the kind of everyday questions that deserve a clean, honest answer. Every tool here is browser-only, free, ad-supported, and written by a human (specifically, this one). I authored every one of the 108 calculators currently on the site, including the maths, the explanations, the "Prove it" workings and the meta. There is no content team, no farm, no prompt-and-publish pipeline. If a calculator is wrong, the person to blame is me, and the contact form goes straight to my inbox.

You can read more about the consultancy and client work at yeseo.io. The personal-brand site, including coaching and speaking, lives at andrewlaws.com. The blog and the more discursive end of things, including the occasional rant about modern web nonsense, is over at lawsie.com. I am also on LinkedIn if that is your preferred medium for professional small talk. All four are dofollow on purpose: this is the same person, in the same chair, writing under the same name.
