Does the page on which you're running surfer link to that website?

Can you show us exactly what you mean (with a screenshot or a copy and paste of Command Window text) by "encountering" that website?

No, the page on which I'm running surfer does not link to that website.

I transferred the ouput of my results on a '.csv'. So, PFA two images with the surfer run on two different websites, both of which have either 'ogp.me' or 'opengraphprotocol.org' (both of which link to the same website), in their results.

I recitified the issue by adding those two pages to the skip list in 'surfer' function. But I would still like to understand why that happened.

Thanks

P.S: I'm only able to insert one image per comment, so the other image will be in my next comment. The first website is the page on which I ran the 'surfer' function.
