Are there any resources around ways to optimize my site to show up for more LLM queries?
1. One of the sites was dev.to, meaning that is one of the sites that it is crawling. You could write an article there, linking back to your site for more info. Just make sure the article is substantive in case they have an intelligent quality filter. Also, announce the article in social media and in your own circles to bring traffic, which might make it easier for the crawler to find, rather than pass over an article that's at the bottom of the stack because of less interest. Do this for any other sites that show up as references and let you post, though you should write unique articles because you don't want to spam the crawler.
2. Look for any sites that might have link lists. This might be old school, but when everyone was doing their own web sites, we had categorized link lists for related sites. Swapping links was good for everyone's traffic and good for the community.
Also, you might want to put an allow in your robots.txt to ensure you're explicitly inviting the crawler. Here's the details on ChatGPT, though you can learn more about other LLMs by visiting their site:

Essentially, do the research to find sites that are being crawled and try to figure out how to build paths for the crawler to find you in the link graph.
