I don't think that it is a good strategy, but it makes sense, especially for content that you want to be scraped (like product pages).
The SEO solution is to be in the list of results that the search engines return to the LLM. That list is relatively small.
You don't even get into the "LLM evaluation" stage unless you're one of the top X number of results for the LLM search. Being that the LLM search uses the search engines and not the LLM, it's fatal if you don't score high enough for the search engines. Whatever makes your results top hits for the search engine is what it will take to get the LLMs to notice you in the future.
ie - for now, OpenAI is dependent on the search engines when doing research. So it's actually the search engines that represent the gatekeeper.
SEO practices are mainly guesses and superstition. The principles of making a well structured website were known in 2000 and haven't changed.
But your well structured site will be ignored both by search engines and by llms. And that is all there is to it, really.
