Working on a website that also has a job board, and over 4000 active job ads. All of these ads are listed on a single "job board" page, and not linked to from anywhere else. Both Ahrefs and SEMRush are thus listing all of these job ad pages as orphans.
How much of a red flag are these orphan pages? Do sites like Indeed have this same issue? Their job ads are completely dynamic, how are these pages indexed?
What is the best way to solve this issue? Create a job category page and link to each individual job ad from there? Any simpler and perhaps more obvious solutions? What does the website structure need to be like for the problem to be solved?
