The content of the PPT is very limited, it's just an outline and necessary presentation, the real content is in the delivery.
So, I still suggest that if it's convenient for you, to truly benefit from it, try to attend such events in person in the future.
What's important is that the core of these kinds of meetings isn't in the presentation part, but in taking advantage of the opportunity the event provides to expand your network. In the SEO industry, there are rarely occasions where people are gathered as completely together; there are also rarely so many companies with extremely high attention on SEO present at the same time. It's a good opportunity to discover business opportunities, find talent, and seek development.
