How Many Backlinks Do I Need to Rank? How to Estimate Your Number

Why there is no single answer

"How many backlinks do I need?" depends on who you are competing against. For "best CRM", the ranking pages have links from thousands of sites. For "CRM for tattoo studios", the top results might have a handful.

Links also are not interchangeable. One link from a respected industry publication can outweigh dozens from unrelated blogs. So the useful question is: how many relevant referring domains do the pages I am competing with have, and how does my page compare on content?

Backlinks vs referring domains

Two numbers often get confused:

• Backlinks: the total number of links pointing to a page or site. One site linking 500 times from its footer counts as 500 backlinks.
• Referring domains: the number of unique sites linking. That same footer link counts as 1 referring domain.

Referring domains are a far better predictor than raw backlink counts, because repeated links from the same site add little. Always compare referring domains.

Also separate page-level links (links to the specific ranking URL) from domain-level links (links to the whole site). A strong domain can rank a new page with few direct links; a weak domain needs more page-level links.

The 5-step estimate

1. Search your target keyword in a private window, in the country you target. Note the top 5 organic results (skip ads and forums for this step, but note them; forums ranking is a sign of weak competition).
2. Look up each URL in a backlink tool (Ahrefs, Semrush, Moz or similar). Record page-level referring domains and the domain's overall rating.
3. Take the median page-level referring domains of the top 5. That is your working target.
4. Adjust for domain strength: if your domain is much weaker than theirs, plan for more page-level links than the median; if similar, the median is a fair target.
5. Adjust for relevance and content: if your page is clearly better and your links will be more relevant, you may need fewer.

Example: top 5 results have 4, 9, 12, 15 and 40 referring domains. Median = 12. Your new domain is weaker than most of them, so plan for 12-20 relevant referring domains to that page, plus a strong page.

Rules of thumb by competition level

These ranges come from our own experience working with new and small sites. Use them only as a starting point before you run the 5-step estimate:

• Low competition (long-tail, specific, forums in the top 5): 0-10 relevant referring domains to the page, sometimes none if the site has some authority and good internal links.
• Medium competition (niche commercial terms, mostly small and mid-size sites ranking): 10-40 referring domains.
• High competition (broad commercial terms, big brands ranking): 50 to several hundred, plus a strong domain overall.

For a brand-new site, target the low and medium tiers first. See keyword research for a new SaaS for how to find them.

Quality factors that change the math

When you count, weigh each link by:

• Relevance: is the linking site about your topic?
• Traffic: does the linking site get real organic traffic? Tools estimate this.
• Placement: in body content, not footers, sidebars or author boxes.
• Indexation: is the linking page itself indexed by Google?
• Attribute: dofollow links typically carry more ranking weight than nofollow, though Google treats nofollow as a hint. See dofollow vs nofollow.

Third-party metrics like DA and DR are useful shorthand for comparing sites, but they are not Google metrics. See DA vs DR explained.

Closing the gap

Once you have a target, plan how to get there:

• Gap analysis: list the sites that link to two or more of the top-ranking pages but not to you. They already link to this topic and are your warmest outreach targets.
• Internal links: point links from your strongest pages to the target page with descriptive anchors. This is free and often underused.
• Linkable asset: add a tool, template or data to the target page so it deserves links.
• Steady pace: spread link acquisition over weeks, not days.
• Measure: record the page's position before, then check every two weeks. Ranking changes from new links often take several weeks to appear.

If you need to reach the target faster, our backlinks service places links in relevant content and shows every placement in a dashboard.

When more links will not help

If your page has matched the competition's referring domains and still does not rank, the issue is probably elsewhere:

• Intent mismatch: the top results are a different page type (lists vs product pages).
• Weaker content: missing subtopics, outdated information, no examples.
• Technical issues: the page is not indexed, canonicalized elsewhere, or slow.
• Cannibalization: two of your pages compete for the same query.

Fix these first. Links amplify a good page; they rarely rescue a page that does not deserve to rank.

Splitting effort between homepage and inner pages

New sites often point every link at the homepage. That builds domain-level strength slowly but rarely ranks the pages that convert. A practical split for a new SaaS:

• About 30-40% of links to the homepage and brand pages, mostly from listings, profiles, launches and press. These come naturally with branded anchors.
• About 40-50% to the pages you most want to rank: comparison pages, use-case pages, key guides.
• About 10-20% to linkable assets (free tools, data, templates), which then pass authority to other pages through internal links.

Then use internal links deliberately: from each linked asset and guide, link to the commercial pages with descriptive anchors. This lets a modest number of external links lift a larger set of pages.
