TABLE OF CONTENTS Protocol Buffers (Protobuf) is a statically typed data serialization format developed and used extensively by Google. Its purpose is similar to JSON, but it is significantly more compact, faster to serialize and deserialize, and requires a predefined message schema for both encoding and decoding. A Protobuf message is binary data. Since binary data cannot be embedded directly in URLs or other text-based formats, it is often Base64-encoded before transmission.

Prompt Engineering focuses on shaping a model call, while Loop Engineering focuses on what happens after that call: how an agent observes the result, updates its state, chooses the next action, and decides whether to continue. The difference sounds simple. But it is hard to feel until you build something where the model has to keep going: A conceptual Loop Engineering loop, from trigger and state to tools, observations, memory updates, and the stop condition.

July 20, 2026. The U.S. District Court for the Northern District of California granted our motion to dismiss Google’s lawsuit, marking a win not just for SerpApi, but for all who depend on an open internet. We’re pleased that the court rejected Google’s attempts to expand the DMCA to assert control over access to public pages. The internet’s founding principle – open access to usable information – is essential to driving innovation and ensuring everyone benefits from the promise of data.

Over the past several years Google Search had one of the biggest transformations in its history. Now it does way more than just rank pages. AI Overviews, AI Mode, generated interfaces, and search agents are changing what happens after a query is submitted. Three years ago, Google's generative search was an experiment behind a waitlist. By the middle of 2026, AI Overviews reached more than 2.5 billion monthly users.

When you search for a person, place, movie, TV show, city, or other topic with Google Search, you might get a card the top of the page with organized details. For movie searches, the card might contain ratings, where to watch it, the release date, the genre, and other information. That's called the Knowledge Graph, and under the hood, it's powered by the Knowledge Graph ID (kgmid) database. Every person, place, or thing that Google can identify has a Knowledge Graph ID.

Blog TABLE OF CONTENTS In the last part of this series, we looked at how web pages are loaded into the browser, and how the content that is downloaded (HTML & CSS) is designed for humans to understand, primarily visually. We also discussed that for a machine, parsing (or understanding) this content works differently. Instead of using a medium that's designed to organise information visually, for the machine we need a medium that organises information semantically.

TABLE OF CONTENTS Whether you're building a travel booking platform, an AI travel assistant, a corporate travel tool, or an accessibility-focused application, providing accurate accessibility information can make a meaningful difference for your users. The challenge is that this information is often spread across multiple Google services in different ways.
