HOW SEOS ARE USING COMMON CRAWL'S WEB GRAPH DATA FOR AI RANKING SIGNALS

Summary from the TLDR Marketing newsletter

AI visibility is increasingly tied to how often a site appears in Common Crawl data, and that frequency is influenced by link-based authority metrics like Harmonic Centrality (HC) and PageRank. Common Crawl uses HC to determine crawl priority, and sites with higher HC scores are crawled more frequently. More frequent crawling means more appearances in monthly archives, which means greater representation in AI training data. Research also shows that traditional Google rank still matters. Position 1 pages have a 46-48% chance of AI citation versus about 19-20% at position 10.
