I recently began work on an existing Wordpress website that was revamped about 3 months ago. https://thedoctorwithin.com. I'm a bit new to Wordpress, so I thought I should reach out to some of the experts in the community.Checking ‘Not found’ Crawl Errors in Google Search Console, I notice many irrelevant links that are not present in the website, nor the database, as near as I can tell. When checking the source of these irrelevant links, I notice they’re all generated from various pages in the site, as well as non-existing pages, allegedly in the site, even though these pages have never existed. For instance: https://thedoctorwithin.com/category/seminars/newsletters/page/7/newsletters/page/3/feedback-and-testimonials/        allegedly linked from: https://thedoctorwithin.com/category/seminars/newsletters/page/7/newsletters/page/3/ (doesn’t exist) In other cases, these goofy URLs are even linked from the sitemap. BTW - all the URLs in the sitemap are valid URLs. Currently, the site has a flat structure. Nearly all the content is merely URL/content/ without further breakdown (or subdirectories). Previous site versions had a more varied page organization, but what I'm seeing doesn't seem to reflect the current page organization, nor the previous page organization. Had a similar issue, due to use of Divi's search feature. Ended up with some pretty deep non-existent links branching off of /search/, such as: https://thedoctorwithin.com/search/newsletters/page/2/feedback-and-testimonials/feedback-and-testimonials/online-continuing-education/consultations/  allegedly linked from: https://thedoctorwithin.com/search/newsletters/page/2/feedback-and-testimonials/feedback-and-testimonials/online-continuing-education/ (doesn't exist). I blocked the /search/ branches via robots.txt. No real loss, since neither /search/ nor any of its subdirectories are valid. There are numerous pre-existing categories and tags on the site. The categories and tags aren't used as pages. I suspect Google, (and other engines,) might be creating arbitrary paths from these. Looking through the site’s 404 errors, I’m seeing the same behavior from Bing, Moz and other spiders, as well. I suppose I could use Search Console to remove URL/category/ and URL/tag/. I suppose I could do the same, in regards to other legitimate spiders / search engines. Perhaps it would be better to use Mod Rewrite to lead spiders to pages that actually do exist. Looking forward to suggestions about best way to deal with these errant searches. Also curious to learn about why these are occurring. Thank you.
