How many backlinks do you need to rank on page 1 of Google? It is one of the most common questions in SEO and the answer is always the same: it depends. But that answer is not actually useful unless you know what it depends on and how to work out the right number for your specific situation.
This guide walks through exactly how to calculate the link building requirement for any target keyword based on real competitive data rather than guesswork.
Why There Is No Universal Number
The number of backlinks needed to rank on page 1 varies by keyword competition, niche, the quality of existing links, the topical authority of your domain, and dozens of other on-page and off-page factors. A local plumbing keyword might require 10 to 20 quality links. A competitive finance keyword targeting a national audience might require hundreds.
Anyone who gives you a fixed number without analysing your specific competitive landscape is guessing. The only reliable method is to look at what the pages currently ranking on page 1 have in terms of links and reverse-engineer from there.
How to Calculate Your Link Building Requirement
Step 1: Analyse the top 10 results
Search your target keyword in Google. Open Ahrefs Site Explorer for each of the top 10 ranking pages. Record the number of referring domains for each page. This gives you a baseline for what Google has already decided is sufficient authority to rank in your competitive landscape.
According to Ahrefs research on backlinks and rankings, the correlation between referring domain count and ranking position is stronger than any other single off-page factor. The number of unique domains pointing to a page matters more than the raw number of backlinks.
Step 2: Find the median and the floor
Rather than targeting the average referring domain count of all 10 results, look at the page ranking in positions 7 to 10. This is the floor, the minimum link authority currently sufficient to appear on page 1. Your target is to exceed this floor while building toward the median of the top 5.
If the page in position 10 has 35 referring domains and the median of positions 1 to 5 is 120 referring domains, your initial target should be around 40 to 50 unique referring domains to enter page 1, with a longer-term target of 100 or more to compete for the top 3 positions.
Step 3: Assess your existing link profile
How many referring domains does your target page currently have? Subtract that from your target number. The result is your link building requirement. A page with 15 referring domains targeting a floor of 40 needs 25 more quality links before it has a realistic chance of entering page 1.
Step 4: Adjust for quality
Not all referring domains carry equal weight. If the top-ranking pages have links from DR 60 to DR 80 publishers and your existing links are primarily from DR 20 to DR 30 sites, you need proportionally more links to match their authority. Quality reduces quantity requirements; a smaller number of high-DR editorial links from relevant publishers can outperform a larger volume of weaker links.
How Long Does It Take?
Most SEO professionals recommend building links at a rate that mirrors natural editorial growth for your domain size. For a smaller site targeting moderate competition keywords, 4 to 8 quality links per month is a typical sustainable rate. At that pace, reaching a target of 40 additional referring domains takes 5 to 10 months.
Ranking results typically appear before you hit the full target. Most campaigns see meaningful position improvements after 8 to 15 quality links are indexed, with page 1 appearance coming as the total approaches the competitive floor identified in the analysis.
The Quality vs Quantity Decision
Given the choice between 50 DR 30 links and 15 DR 60 links from topically relevant editorial publishers, the 15 higher-quality links will almost always produce better ranking outcomes. Google’s algorithms weight the quality and relevance of linking domains alongside their quantity.
This is why we set a minimum DR 40 threshold on all editorial link building at White Hat Works, with most placements landing DR 50 to DR 75. Fewer, higher-quality links produce more predictable ranking movement than volume-based approaches.
