With a few days to think about this:
1. Kyle's right about using
kayak.com data to validate - or even
kayak.ai data to validate - whether a "share" is worth indexing. Some sort of "review of quality" is needed before spammers are creating "backlinks"
a. Right now their use of parameters and indexing different countries concerns me on their XML sitemap.
b. Their XML sitemap hasn't really budged since their launch, which is a good thing.
i. That being said, I haven't been messing with browser user-agents to test it (they could very well be doing this to throw off some competitors, but IYKYK)
c. We'll know this is a serious play when
kayak.ai is promoted.
d. Depending on how tight they'd want to define their clusters via embeddings, you could see a lot of shares actually all redirect to a "canonical" share that's both most popular but similar in intent.
2. Doing tests like this (Throw your website as an AI chat wrapper) on a separate domain will become a new norm if LLM's to unlock data for providers of content and experiences.
3. If the app is helpful and people are sharing really helpful trip plans... then the content is actually not crap or considered doorway pages. How judicious you are with various signals to shared trip plans on indexing is what makes or breaks this UGC programmatic SEO play.
a. Spammers will need prompt engineering skills to get the right kind of response from an LLM which benefits their blackhat plays - which may also serve as a deterrent - but every hack that gets through can be collected as an edge case to train against.
b. Travel planning isn't a DAU kind of activity, let alone WAU. To make habits stick you need usage. Without usage, everything falls apart.
