Introduction to Web Standards
Google’s Search Relations team members, Martin Splitt and Gary Illyes, recently shared their insights on web standards on the Search Off the Record podcast. They explained how these standards are created and why they matter for Search Engine Optimization (SEO). Their conversation reveals details about Google’s decisions that affect how we optimize websites.
Why Some Web Protocols Become Standards
Google has formally standardized robots.txt through the Internet Engineering Task Force (IETF). However, they left the sitemap protocol as an informal standard. This difference illustrates how Google determines which protocols require official standards. Illyes explained that with robots.txt, there was a benefit because different parsers tend to parse robots.txt files differently. On the other hand, sitemaps are simple XML files, and there’s not much that can go wrong with them.
Priorities in Standardization
This statement from Illyes reveals Google’s priorities. Protocols that confuse platforms receive more attention than those that work well without formal standards. Google focuses on standardizing protocols that have a significant impact on how websites are crawled and indexed.
Benefits of Protocol Standardization for SEO
The standardization of robots.txt created several clear benefits for SEO:
- Consistent implementation: Robots.txt files are now interpreted more consistently across search engines and crawlers.
- Open-source resources: The standardization of robots.txt allowed Google to open source their robots.txt parser, and people started building on it.
- Easier to use: Standardization means there’s less strain on site owners trying to figure out how to write the files.
The Web Standards Process
The podcast also revealed how web standards are created. Standards groups, such as the IETF, W3C, and WHATWG, work through open processes that often take years to complete. This slow pace ensures security, clear language, and broad compatibility. Illyes explained that you have to show that the thing you are working on actually works, and there’s tons of iteration going on, which makes the process very slow but for a good reason.
Participating in Web Standards
Both Google engineers emphasized that anyone can participate in these standards processes. This creates opportunities for SEO professionals to help shape the protocols they use on a daily basis. By participating in web standards, SEO professionals can contribute to the development of protocols that affect their work.
Security Considerations in Web Standards
Standards also address important security concerns. When developing the robots.txt standard, Google included a 500-kilobyte limit specifically to prevent potential attacks. Illyes explained that when reading a draft, he would look at how he would exploit stuff that the standard is describing. This demonstrates how standards establish security boundaries that safeguard both websites and the tools that interact with them.
Practical Strategies for SEO Professionals
For SEO professionals, these insights indicate several practical strategies to consider:
- Be precise when creating robots.txt directives, since Google has invested heavily in this protocol.
- Use Google’s open-source robots.txt parser to check your work.
- Know that sitemaps offer more flexibility with fewer parsing concerns.
- Consider joining web standards groups if you want to help shape future protocols.
Conclusion
In conclusion, understanding web standards is essential for SEO professionals. By knowing how standards are created and why they matter, SEO professionals can optimize their websites more effectively. The standardization of protocols like robots.txt has created several benefits, including consistent implementation, open-source resources, and easier use. By participating in web standards and considering security concerns, SEO professionals can contribute to the development of protocols that affect their work and improve their SEO performance.
