Link Building Then and Now: What Actually Changed Since 2018

So here's something interesting - link building in 2025 looks pretty different from what people were doing back in 2018. If you're just getting into SEO now, you might hear conflicting advice because the field shifted quite a bit over these seven years.

2018-2019: The Guest Post Gold Rush

Back then, everyone and their cousin was doing guest posts. You'd pitch websites, write a 1000-word article, slip in your link, and call it a day. People were also big on blog commenting and directory submissions. Honestly, a lot of it was pretty spammy, but Google's filters weren't as sharp as they are now.

2020-2021: Content Got Serious

This is when things started changing. Google's algorithm updates got better at spotting low-effort content. Suddenly, those thin guest posts weren't cutting it anymore. People began focusing on longer, research-backed pieces. The phrase "10x content" was everywhere - basically, make something ten times better than what's already ranking. Digital PR started gaining traction too, where you'd create newsworthy content to earn links from actual journalists.

2022-2023: Relationships Over Transactions

Here's where the shift really happened. Instead of cold-pitching hundreds of sites, successful link builders started building actual relationships. Podcasts became huge for this. You'd appear on someone's show, have a real conversation, get a link. Same with expert roundups and collaborative content. The emphasis moved from "how many links" to "how good are these links."

2024-2025: Quality and Relevance Won

Now we're at a point where one solid link from a relevant site in your niche beats fifty random directory links. People are focusing on earning links through genuinely useful resources - think free tools, original research with data, comprehensive guides that other sites want to reference. HARO (Help a Reporter Out) and similar services are still working, but you need to provide real expertise, not generic quotes.

The biggest lesson from this timeline? Link building got harder but more honest. You can't really game it anymore with shortcuts. You need to create something worth linking to, then let the right people know it exists. That's basically where we are in 2025.
