Every so often, someone announces that "link building is dead." And every so often, it proves to still be one of the ranking factors Google weighs most heavily. The reason is simple: a link from another site is, to Google, a vote of confidence. The more quality votes you get, the more Google trusts that your content deserves to rank higher.
Not all links are worth the same
A link from a relevant publication in your industry carries far more weight than a hundred links from irrelevant or low-quality sites. In fact, an excess of low-quality links can hurt more than it helps. Quantity without quality is worthless — worse, it can be counterproductive.
Legitimate ways to earn links
The strategies that work long-term are the ones that offer something real: content so useful others want to link to it naturally (guides, original research, free tools), genuine relationships with industry blogs and publications, press mentions when you do something newsworthy, and real collaborations with complementary brands or businesses.
What to avoid
Buying links in bulk from link farms, joining automated link-exchange networks, or hiring services that promise "1000 links for 20 euros" are nearly guaranteed ways to get your site penalised, not improved. Google detects these patterns increasingly well.
How to know if your link profile is healthy
Tools like Google Search Console (free) show which sites link to yours. A healthy profile has links from varied, relevant domains for your industry, earned gradually over time, not in artificial, suspicious spikes.
Frequently asked questions
How many links do I need to rank well?
There's no magic number. The quality and relevance of each link matters far more than the total count. Ten links from relevant sites in your industry are worth more than a thousand from irrelevant ones.
Is buying links always a bad idea?
Buying links in bulk, in a detectable way, yes. It's against Google's guidelines, and the penalty risk far outweighs any short-term benefit.
How long does it take to build a good link profile?
It's one of the slowest SEO processes: think months or even years for businesses starting from zero, though the pace picks up if your own content is genuinely good and shareable.
