What Are Link Building Tools?
Link building tools are SEO tools that help you acquire, analyze, and track backlinks — the hyperlinks from other websites to yours. When a high-authority website links to your page, it passes “link equity” — a ranking signal that tells Google your page is trusted and worth ranking higher. According to Google’s explanation of how search works, backlinks remain one of the most important signals for determining which pages to show in search results.
Not all backlinks are equal. A single link from a DA 70 news site can be worth more than 100 links from DA 5 blogs. Quality, relevance, and anchor text diversity all matter. Before building links, you need to know your current DA baseline — and that’s exactly what our free link building tools provide. See Moz’s guide to backlinks for a comprehensive overview of how link signals work in modern SEO.

Link Building Best Practices
The six rules of safe, sustainable link building that Google rewards.
Prioritize Relevance Over DA
A DA 35 link from a site in your exact niche outperforms a DA 60 link from an unrelated site. Topical relevance is a stronger trust signal than raw authority score. Use these to identify niche-relevant prospects.
Diversify Anchor Text
Use branded anchors (your site name), naked URLs, generic text (“click here”), and partial-match keywords. Over-optimized exact-match anchors (70%+) trigger Google’s spam filters.
Build Links Gradually
Gaining 100 links overnight looks unnatural. Build 5–15 quality links per month consistently. Gradual growth signals organic popularity rather than manipulation.
Disavow Toxic Links
Check spam score quarterly. If above 30%, identify toxic links and submit a disavow file via Google Search Console. One bad link farm can suppress all good links.
Create Link-Worthy Content
Original research, free tools, comprehensive guides, and infographics earn links naturally. The best link building strategy is content so useful people link to it without being asked.
Don’t Neglect Internal Links
Internal linking is free link equity redistribution. Every new page should receive 3+ internal links from existing high-authority pages — it’s the fastest ranking boost most sites ignore.
