Glenn Gabe Unveils Google Algorithm Update Patterns

Glenn Gabe is an independent search consultant who monitors changes to Google Search before they are announced. He documents his findings on his blog, The Internet Marketing Driver, which has been running since 2006. Gabe's analysis helps the marketing community stay informed about algorithm updates and their impact on websites.

Gabe's method involves tracking volume and analyzing query and landing-page performance using data from Search Console API exports and third-party tools like Semrush, Ahrefs, and Sistrix. He identifies three possible causes for a drop in traffic: relevancy adjustment, intent shift, and overall site quality. Only the latter is addressable, and Gabe emphasizes that quality issues are often complex and multifaceted.

Gabe's expertise has made him a go-to source for information on Google algorithm updates. He has been documenting changes since 2006 and has developed a reputation for accuracy. His analysis has helped marketers understand the impact of updates like the Phantom update in 2015, which affected how quality is assessed.
