Back in the old days of SEO, we loved any link if it was free, even if it was from a spammy scraper site or the lowest-quality directory you’ve ever seen. If we did nothing to get that link, it was a great link. People assumed that all links were beneficial — and that even “bad” links were completely harmless, with no potential to cause damage.
Then we started to get scared… and we nofollowed links. We performed loads of link analysis and reached out to sites that we thought were spammy and asked to have our links removed. Oh, and let’s not forget that time period where we were terrified of exact-match anchors and then built 50 links that all said “Click here.”
