Sometimes you want your website/PWA to be crawled by bots and visible to search engines, and sometimes you don't. We allow you to choose.
On an ID's navigation bar you will have an "SEO" tab. Select it to see your SEO controls.
Turn on SEO if you want your page to be crawled.
You can also control the "metadata" (information that a computer understands) so that a search engine better ranks and categorized you page. The information on the SEO tools page is also what the search engine will most likely use for the preview it shows of your page. It is important to write this information to influence people seeing the preview to click through to your page.
