QUICK ANSWER

What is SEO?

SEO (search engine optimization) is the practice of improving a website so it ranks higher in search engines like Google and appears in AI answers, bringing more relevant visitors without paying per click. It covers technical health, content, on-page optimization and authority.

What does SEO stand for?

SEO stands for search engine optimization. The search engine optimization meaning is simple: making pages easier for search engines to find, understand and trust, so they show them to people searching. Sources like the SEO Wikipedia entry describe the same core idea.

What do the numbers say about SEO and AI search?

Research presented at KDD 2024 (Aggarwal et al., Princeton University and IIT Delhi) found that adding citations, quotations and statistics can boost a source's visibility in generative engine responses by up to 40%, while classic keyword stuffing performed worse than doing nothing. Google's Core Web Vitals define a good experience as Largest Contentful Paint within 2.5 seconds, Interaction to Next Paint of 200 milliseconds or less and Cumulative Layout Shift of 0.1 or less, measured at the 75th percentile of page loads (web.dev). Toffyjar SEO retainers cost $499 a month for Starter and $999 a month for Growth, with Enterprise priced on scope, and every plan includes GEO for AI search. Put simply, rankings now depend on fast pages and answers that cite real sources, and the same work also earns citations in AI Overviews, ChatGPT and Perplexity.
