@shubr86 Thanks a lot for getting the information over. I can’t see anything to stands out from your Site Health information and your story is passing AMP validation so looks good.
I did notice that you are not on the latest version of Web Stories so I would recommend updating to the latest version if you can but this shouldn’t make any difference to your traffic to your stories.
As you Web Stories setup looks good I would say that questions about search rankings and traffic are generally better suited for Google Search Central, as they go a bit beyond our support offering for the Web Stories WordPress plugin.
That being said, it is not unusual to see spikes and declines in traffic, for example when content is being featured on Google Discover. At the same time, Google Search is constantly improving its algorithms, which can affect ranking. Linking to / embedding stories from other places on your sites and following the recommendations from the pre-publish checklist is a good way to ensure your users will find your stories.
If you’re not sure whether a change in traffic is caused by a change to your site, use Search Console’s various tools to see if your content is properly crawled and indexed. The help resources at Google Search Central can further help debug cases like this.
