When I started playing around with these tags, my Google PageSpeed score for **Accessibility** jumped to 100. Before I got flagged for missing the Main Landmark. Is there any info in the manual about the different Advanced HTML Tags and how to use them? @dan ![Container Advanced Tag](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/9/8/982979053989bd3089b117b5afb15ba00e84bfe7.png) ![Container Advanced Tag Main](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/9/6/96aaf3e9953d4950f450454ffa20a57c4b90f0c1.png) ![PageSpeed Desktop](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/6/b/6b039f279ff6f32bf9c4d428915e093fb4b8cc8f.png) ---

I tested some more tag settings and **Performance** improved from 90 to 94. I will not get 100 since my photos are too large and not enough compressed … ![PageSpeed Desktop-94](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/5/4/5434651ad50b52c7eb18cd99aaf1d48e2f06b2e7.png)
