Third-party cookie deprecation lets Google please privacy advocates while harming competitors.  Lest the competitive benefits become too clear, the company is eager to show that advertisers can get acceptable results from alternatives like contextual targeting, interest-based cohorts, and publishers’ first-party data.  It just released a test concluding exactly that: ad campaigns without third party cookies performed only a little worse than those using cookies. (Details here.) They mention but don’t stress that the test doesn’t consider lost measurement or retargeting.

If you still think that MCP stands for Male Chauvinist Pig, well, the 1970’s want their disco ball back. Today’s hep cats know that MCP stands for Model Context Protocol, a new-but-widely supported standard that lets large language models access structured data as context for their prompts. Early adopters include Salesforce and Adobe, and search platform Algolia is now using it to feed their data to customer-facing real-time AI agents.
