Backlinks remain one of the most powerful ranking factors in SEO. Quality backlinks signal to search engines that your content is valuable and trustworthy. Here's how to build them without spending a dime.
What Are Backlinks?
Backlinks are links from other websites pointing to your site. Think of them as votes of confidence. The more quality backlinks you have, the more authority your site gains in search engine rankings.
Proven Strategies to Get Free Backlinks
1. Guest Blogging
Write valuable content for other websites in your niche. In return, you get a backlink in your author bio or within the content.
How to Find Guest Post Opportunities:
- •Search Google:
"your niche" + "write for us" - •Search:
"your niche" + "guest post guidelines" - •Search:
"your niche" + "contribute" - •Check where your competitors are guest posting using Ahrefs or SEMrush
Pro Tip: Pitch unique angles, not generic topics. Editors receive hundreds of pitches -stand out with data-driven or contrarian takes.
2. Broken Link Building
Find broken links on relevant websites, create similar content, and reach out to suggest your link as a replacement.
Step-by-Step Process:
- Install the "Check My Links" Chrome extension
- Visit resource pages in your niche and scan for broken links
- Create content that matches or improves upon the dead page
- Email the site owner: "I noticed a broken link on your page... I have a similar resource that might help"
Pro Tip: Use Ahrefs' "Broken Backlinks" report to find broken pages with existing backlinks, then recreate that content.
3. Resource Page Link Building
Many websites maintain curated resource pages listing helpful tools and content. Getting listed can provide high-quality, relevant backlinks.
How to Find Resource Pages:
- •
"your niche" + "useful resources" - •
"your niche" + "helpful links" - •
"your niche" + inurl:resources - •
"your niche" + inurl:links
Pro Tip: Create a genuinely useful resource (free tool, calculator, or comprehensive guide) before reaching out.
4. HARO & Journalist Outreach
Help A Reporter Out (HARO) connects journalists with expert sources. Respond to queries and get featured in news articles with backlinks.
Top Platforms for PR Backlinks:
- •Connectively (formerly HARO) - connectively.us

- •Featured.com - featured.com
- •Twitter/X - Search #journorequest
Pro Tip: Respond within 1-2 hours of receiving a query. Include your credentials and a concise, quotable answer.
5. Create Linkable Assets
Create content so valuable that others naturally want to link to it. These "link magnets" can generate backlinks for years.
High-Performing Linkable Asset Types:
Pro Tip: Statistics pages are link magnets. Create "[Your Industry] Statistics 2025" and update it annually.
6. Skyscraper Technique
Find content that already has lots of backlinks, create something significantly better, then reach out to sites linking to the original.
How to Execute:
- Find popular content in your niche using Ahrefs or BuzzSumo
- Analyze why it earned backlinks (data, design, depth?)
- Create a 10x better version (more current, detailed, visual)
- Email everyone linking to the original piece
Pro Tip: Don't just make it longer -make it better. Add original data, expert quotes, and updated information.
7. Unlinked Brand Mentions
Find websites that mention your brand but don't link to you. A simple outreach email can convert these mentions into backlinks.
How to Find Unlinked Mentions:
- •Set up Google Alerts for your brand name
- •Use Ahrefs Content Explorer: search brand, filter "highlight unlinked"
- •Search:
"your brand" -site:yourdomain.com
Pro Tip: These have 40-50% conversion rate because the author already knows your brand.
8. Community Participation
Engage genuinely in forums and communities. Provide real value first -backlinks come naturally when you're seen as a helpful expert.
Best Platforms by Niche:
Pro Tip: Follow the 80/20 rule -80% helpful comments without links, 20% with relevant links.
