8 Big SEO Changes over the last Decade by Jason DeMers #346

According to Jason Demers via Search Engine Land, the eight biggest changes are the rise of content, the death of link schemes, the reshaping of local search, SERP overhauls, the rise of the knowledge graph, mobile prioritization, the death of keyword stuffing via semantic search, and the shift to continuous core algorithm updates instead of random major rollouts.

Competitors continue making changes that can push your rankings down, and Google constantly updates its algorithm and SERPs. Panda and Penguin now run continuously as part of the core algorithm, so sites must keep content relevant and link profiles clean at all times.

Hummingbird, released in 2013, introduced semantic search. It shifted SEO focus from matching exact keywords and keyword density to understanding searcher intent, meaning Google tries to determine what the user actually means and serves results accordingly, even without exact keyword matches.

The knowledge graph gives users direct answers on the search results page, so they often do not need to click through to a website. This means well-optimized sites can lose traffic even when their content is selected as the best answer, because Google surfaces it without a click.
