Backlinks remain one of the strongest ranking signals in Google’s algorithm. A backlink is a link from another website to yours — each one acts as a vote of confidence that tells Google your content is valuable and trustworthy. Building quality backlinks is the most effective way to increase your site’s authority and rankings.
What Makes a Good Backlink
- Relevance: Links from sites in your industry or related topics carry more weight than random sites
- Authority: Links from high-authority sites (DR/DA 40+) pass more value than links from new or low-authority sites
- Editorial placement: Links placed naturally within content are more valuable than links in footers, sidebars, or comment sections
- Dofollow: Dofollow links pass ranking value; nofollow links provide less direct SEO benefit but still contribute to a natural link profile
- Anchor text: Descriptive, natural anchor text helps Google understand what the linked page is about
Strategy 1: Create Link-Worthy Content
The foundation of all link building — content that other sites want to reference.
- Original research and data: Studies, surveys, and industry data get cited by journalists and bloggers
- Comprehensive guides: The definitive resource on a topic becomes the default link target
- Free tools and calculators: Interactive tools earn links from sites recommending resources
- Infographics: Visual content is highly shareable and frequently embedded with attribution links
- Industry statistics pages: Curated statistics compilations are frequently cited
Strategy 2: Guest Posting
Writing articles for other websites in exchange for a backlink to your site.
- Find targets: Search “[your topic] + write for us” or “[your topic] + guest post” to find accepting sites
- Quality over quantity: One guest post on a relevant, authoritative site beats 10 posts on low-quality sites
- Provide genuine value: Write your best content for guest posts — your reputation is on the line
- Natural link placement: Include links within the body content where they add value, not just in author bios
Strategy 3: Broken Link Building
Find broken links on other sites and suggest your content as a replacement.
- Use Ahrefs or Check My Links (Chrome extension) to find broken links on relevant sites
- Create or identify content on your site that matches what the broken link pointed to
- Email the site owner alerting them to the broken link and suggesting your resource as a replacement
This works because you are helping the site owner fix a problem while earning a link.
Strategy 4: Digital PR
Getting media coverage that includes links to your site.
- HARO / Connectively: Respond to journalist queries with expert quotes — published articles typically include a backlink
- Newsworthy content: Publish original research, surveys, or data that journalists find newsworthy
- Press releases: For genuinely newsworthy events (product launches, major milestones)
- Expert commentary: Offer expert opinions on trending industry topics
Strategy 5: Resource Page Link Building
- Find resource pages in your niche (“[topic] + resources,” “[topic] + useful links”)
- If your content would be a valuable addition, email the page owner requesting inclusion
- Works best when you have genuinely useful resources like tools, guides, or data
Strategy 6: Competitor Backlink Replication
- Use Ahrefs to analyze your competitors’ backlink profiles
- Identify their most valuable link sources
- Determine if you can earn links from the same sources (guest posting, resource mentions, directories)
- Create content that is equal to or better than what earned the competitor their link
Link Building Mistakes to Avoid
- Buying links: Violates Google’s guidelines and risks manual penalties
- Low-quality directories: Links from spammy directories provide no value and can harm your profile
- Excessive exact-match anchors: Unnatural anchor text patterns trigger algorithmic penalties
- Ignoring relevance: Links from completely unrelated sites provide minimal value
- Quantity over quality: One link from a DR 60 relevant site is worth more than 100 links from DR 5 sites
How Many Backlinks Do You Need?
- There is no universal number — it depends on your keyword competition
- Check how many referring domains your top competitors have for target keywords
- Aim to match or exceed their link profile quality (not just quantity) over time
- For most keywords, 10-50 quality referring domains to a specific page is enough to compete
