10 Link Building Strategies That Still Work (and 4 to Drop)
The link building strategies that still work give another site a real reason to cite you: your data, your expertise, a mention you already earned or a fix for their broken page. Anything that only works because money changed hands is a liability.
Google's spam policies class exchanging money, goods or services for links as link spam.
Paid links are fine only when marked with a nofollow or sponsored attribute, which means judging them as advertising.
Swapping links at scale
"Link to me and I'll link to you" in small doses is normal on the web.
Excessive swaps and partner pages that exist only for cross-linking are named in Google's spam policies.
Low-quality directories and bookmark sites
Google lists these explicitly. A handful of real, curated directories in your industry are different, and my take on whether paid business directories are worth it covers where the line sits.
Automated or networked link programs
Tools that create links for you, and networks of sites built to sell placements, are the clearest footprint of all.
Don't panic-disavow, though. Google's disavow guidance says most sites never need the tool, and that it's meant for a considerable number of spammy links tied to a manual action, actual or likely.
Pick Three Strategies and Start This Week
You don't need ten strategies running at once.
Pick three for this month:
Strategy 2 or 3 for quick, relevant wins you've already earned.
Strategy 4 for links that reflect real relationships.
One longer play, such as data, a tool or expert comment.
Before you chase any new link, check the site is worth it with my process for checking backlink quality.
Link building is one part of off-page SEO, alongside reviews, mentions and listings.
And if you'd like someone to run the prospecting, vetting, outreach and reporting for you, here's how I run link building as a hands-on campaign.
Frequently asked questions
What is the most effective link building strategy?+–
For most businesses I work with, the most effective link building strategy is reclaiming what they already earned: unlinked mentions, partner and supplier pages, and links pointing at old URLs that now return errors. After that, original data and expert comment for journalists tend to earn the strongest links, though they take longer to pay off.
How many backlinks do I need to rank?+–
There is no fixed number. It depends on how strong the pages already ranking for your query are, and how relevant their links are. Compare your page with the top results in a backlink tool, look at the kinds of sites linking to them, and aim to close that gap with links of similar quality rather than a target count.
Are guest posts still a good link building strategy?+–
Guest articles still work when the publication has real readers, edits what it publishes and would run your piece without payment. Google's spam policies call out keyword-rich anchor links in articles and guest posts distributed across other sites, so the risk sits in scale, paid placements and optimised anchors, not in writing for a respected trade title.
How long does link building take to work?+–
Reclaimed links can go live within days, but search engines need time to crawl them and reflect them in rankings. PR and asset-led strategies take longer, because the asset has to be built, pitched and picked up. Judge the first months on links earned and referral visits, and expect several months before ranking changes are clear.
