What People Get Wrong About Link Building: A Historical Perspective

I've watched people make the same link building mistakes for years now, and it's worth walking through what's changed and what hasn't since 2018. If you're just starting, this might save you some headaches.
2018-2019: Quantity Over Everything
The biggest mistake back then was obsessing over link counts. People would buy packages of "500 backlinks for $50" and wonder why their rankings tanked. Even legitimate strategies got twisted - someone would do 100 low-effort guest posts instead of 10 good ones. Google was already penalizing this stuff, but the message hadn't fully sunk in yet. Directory submissions were still happening way too much, even though their value had dropped to nearly zero.
2020-2021: Ignoring Relevance
This is when people started understanding quality mattered, but they still missed the relevance piece. You'd see a gardening blog with links from tech sites, finance sites, random lifestyle blogs. Sure, they were "quality" sites, but Google got smarter about topical relevance. A link from a small gardening forum became more valuable than one from a massive but unrelated site. Lots of beginners didn't adjust their strategy to match.
2022-2023: Terrible Outreach
Oh man, the email pitches got so bad during these years. Copy-paste templates that obviously went to 500 people. Subject lines like "Quick Question" or "Collaboration Opportunity." Zero personalization. Site owners were getting dozens of these daily and ignoring all of them. The mistake was treating outreach like a numbers game instead of actual communication between humans.
2024-2025: Forgetting the Content Part
Here's what people get wrong now - they focus entirely on the link-getting part and forget that you need something worth linking to first. You can't pitch mediocre content successfully anymore, no matter how good your outreach is. I see beginners spending hours on outreach for a thin 500-word blog post that doesn't offer anything new. It doesn't work.
Another current mistake is avoiding link building entirely because "it's too hard" or "you can rank without it." Sure, for very low-competition keywords, maybe. But for anything competitive? You need links. Just good ones.
What Actually Works Now
The through-line from 2018 to 2025 is this - shortcuts fail eventually. The strategies that work require actual effort: creating legitimately useful content, building real professional relationships, providing value before asking for anything. That was true in 2018 and it's still true now. The difference is Google got way better at enforcement, so you can't fake it anymore.
