- Answer Engine Optimization (AEO)→
We shape content so AI answer engines (ChatGPT, Perplexity, Google AI overviews) cite YOU: clear claims, structure, sources, schema. The successor discipline to classic SEO in 2026.
- Zero-Click Search→
Searches resolved right on the results page (AI overview, snippet) with no click to any site. Rising fast: you win by being the cited source, not just by ranking.
- Featured Snippet→
The boxed answer Google lifts to the top ("position zero"). Win it with a crisp, directly-phrased answer placed right under a question heading.
- People Also Ask→
Google's expanding box of related questions. Each one is a content opportunity: answer them explicitly to capture the box and the long-tail traffic.
- Crawl Budget→
How many pages a search engine will crawl on your site per visit. It matters for large sites: waste it on junk URLs and your important pages get crawled late.
- Canonical URL→
The <link rel="canonical"> that tells search engines which URL is the master when duplicates or params exist. Prevents ranking signals from being diluted across near-identical pages.
