High potential SEO opportunity or high risk with generative AI + user-generated content?

Tl;dr: Has your SEO been penalized for using AI-generated content? We managed to rank 1st page on Google for certain long tail keywords after only 2 days of indexing. Context: - I recently launched a travel planning site powered by GPT. - As a part of my latest launch, I tested out whether AI content with input prompts from users would rank on Google. For example, someone would search "5 days trip to Costa Rica for less than $1,000" and the AI would write the entire trip. We only direct it to optimize for certain keywords/output in a certain format. - I was quite skeptical at first because a few of my SEO friends warned me against doing so. But with all things considered (new site, nothing to lose), I decided to go ahead instead. Rationale: - My thinking is simple, while big travel sites can easily dominate popular keywords like "5 best things to do in Paris", they wouldn't bother to create very very specific keywords like "A 7 day trip to oregon for a family of 3 that includes a 10 year old" (which is a real travel brief we answer). - And capturing that longtail gap is where we're going to carve out a niche for our site. How did we do it? 1. For every user's travel request, we generate a corresponding itinerary with a nice URL such as /itinerary/trip-to-paris-for-family-of-4. 2. This page is optimized for SEO with AI-generated meta description, h1, h2, and other og social tags. 3. Every day, we would collect all the new URLs created yesterday from 1 & 2 with a simple script & submit the sitemap to Google for indexing 4. We make sure our site would be properly scaled and those URLs wouldn't return any abnormal status like 5xx or 4xx. 5. We wait about 1-2 days for the indexing to happen. 6. We check on certain long tail keywords and compare the result. The outcome: - Our page started to get indexed about 1 day after the sitemap submission request. - When we checked for certain longtail keywords, like "hidden gems in jharsuguda", our page was in the top 4! What does this mean: - It means regardless of whether Google detects AI content, they don't reject you at the indexing step - It also means Google doesn't penalize your ranking as well. Otherwise, my page wouldn't be in the top 4 against the other 90k sites. - But caution: we haven't integrated with any proper keyword planning tools like ahrefs or seomoz so the keywords ranked are not the most efficient (i.e purposely target easy keywords with a decent search volume of around 1k per month). So what do you all think? Anyone with similar experience to share?
