A multi-chapter free guide to Answer Engine Optimization — getting your name into the answers AI assistants give, rather than into a list of blue links. Covers why search behaviour changed, where ordinary SEO still applies, deciding what you want to be known for, and how to measure and scale the work. Written by Nick Lafferty and Nigel Stevens.
Why I recommend it: The clearest free explanation of AEO I have read, and directly useful if you want an assistant to name you or your business when someone asks. Keep the source in view: Profound sells AEO tracking software and has just raised a $180m round, so the guide is built to make you feel you need a tool to do this. Take the method; test whether you actually need the product.
Search Engine Land's free guide by Curtis Weyant, last updated 30 December 2025, arguing the SEO-versus-GEO argument is a false choice and that the real change is visibility splitting across Google, ChatGPT and social platforms. Quotes the competing positions directly, including Google's "good SEO is good GEO" line. About a 13-minute read, free, no sign-up.
Why I recommend it: If you run a small business and you are being sold a separate "GEO package," read this first. It is the most level-headed free piece I have found on the subject, and it is from a trade publication that lives off this industry, so treat its optimism about measurement tools accordingly.
