Google Is Moving More Links Into AI Search Answers. What Should Publishers Change?
Google's October AI Search update adds more visible inline sources, official links and news carousels. Here is what changed and what publishers should measure.
The Inverted Index
A sorted dictionary mapping terms to document IDs. Transform search from O(corpus size) to O(1) lookup, enabling full-text search at scale.
Tries: Why Autocomplete Doesn't Scan Every Word
A trie finds all words with a prefix in O(p) time, independent of dictionary size. Radix compression and top-k heaps make autocomplete instant.
