There has been a lot of speculation about what Google Caffeine will do to search rankings — will it be the Google slap-apocalypse?

Most likely, no.

The people at WebProNews sat down with Matt Cutts from Google to examine the issue. You can watch the video at WebProNews.

His main points were that most people won’t notice a change when Google Caffeine rolls out. He also made a point to say that it would be rolled out slowly and would be tweaked based on user feedback.

At the core, Google Caffeine is only an update to how Google actually crawl’s Web sites, so there should be no quality-score adjustment that could hurt online marketers.

From the article:

This infrastructure modification will lay the foundation for future indexing changes and will also allow for the expansion of website speed and size. Incidentally, it could even provide a stronger architecture for potential real-time and semantic efforts.

Google Caffeine could be laying the framework for the upcoming Google Wave.
