How Many Backlinks Do You Need to Rank?
You need about as many backlinks as the pages you are trying to beat, which is often zero for a long-tail question and dozens of referring domains for a head term. Google ranks pages against each other, not against a quota. Count the referring domains on page one for your keyword and aim for the median.
Why There Is No Single Backlink Number
There is no single backlink number for ranking, since Google scores your page against the other pages that want the same spot, not against a checklist. Google’s own explanation of how results are ranked says it looks at whether “other prominent websites link or refer to the content” as a sign the information is trustworthy. Links are evidence, and the only question is whether your evidence beats the page above you.
So the same page can be over-linked for one keyword and under-linked for another. When nobody on page one has links, zero is a competitive number, which is why you can rank without backlinks on plenty of keywords. When page one is stacked with heavily linked pages, no amount of on-page polish closes that gap for you.
Google’s own people keep pushing the number down, too. Gary Illyes told a search conference in April 2024 that “we need very few links to rank pages,” per Search Engine Journal’s report, and that “over the years we’ve made links less important.” Fewer links are needed, but zero is still not the answer on a term everyone wants.
What the Backlink Studies Actually Show
The backlink studies show that links separate winners at the top of page one and that most of the web never enters the race at all. Read them for the direction, not for a quota, since every study measured everything from “weather” to a question nobody else answered.
| Finding | Number | Study |
|---|---|---|
| Backlink edge of the #1 result over positions 2 to 10 | 3.8x more | Backlinko, 11.8M results |
| Referring-domain edge of the #1 result | 3x more | Backlinko |
| Correlation between referring domains and rank | 0.255 | Ahrefs, top 1M US keywords, 2025 |
| Same correlation for local queries | 0.33 | Ahrefs |
| Pages that get zero Google traffic | 96.55% | Ahrefs, ~14B pages |
| No-backlink pages that clear 1,000 monthly visits | 1 in 6,671 | Ahrefs |
Notice what the 3.8x figure is really telling you. Page one is already full of relevant pages, so links are how Google breaks ties at the top. The gap between #5 and #1 is usually a link gap, and the gap between page three and page one is usually a content gap.
Still, the direction is not in doubt. Backlinko’s study of millions of results found the #1 result averages 3.8x more backlinks than the rest of page one, and Ahrefs’ search traffic study found only 1 in 6,671 no-backlink pages ever clears 1,000 monthly visits. Links are not always the price of entry, but they are usually the price of winning.
Why Links Matter More for Some Keywords
Links matter more for local and head-term keywords than for long-tail questions. Ahrefs’ January 2025 study of the top 1,000,000 US keywords put the correlation between referring domains and rankings at 0.255 overall and 0.33 for local queries, and it found the overall figure slipped from 0.29 in 2019. Links count for less than they did, and they still count most where the competition is thickest.
Even so, both studies measured everything, including brutal head terms. Your keyword is not “everything,” and a store chasing low-competition keywords is playing in the part of the data where linkless pages win every day.
How to Find Your Real Number in Ten Minutes
You find your real backlink number by measuring the five pages already ranking for your keyword and taking the median of their referring domains. It takes ten minutes with any backlink checker, and most have a free tier that shows referring domains for a handful of URLs a day.
- Search your keyword in an incognito window and copy the URLs of the top five organic results, skipping ads and shopping boxes.
- Pull the referring domain count for each URL, the page itself, not the whole site.
- Throw out the outliers, like a Wikipedia page, a giant marketplace, or a forum thread.
- Take the median of what is left. That is your working target.
- Pull your own page’s referring domains and write down the gap.
The counts will disagree between tools, sometimes badly. That is fine, since you are comparing pages inside one tool, not chasing an exact figure.
A Worked Example
A worked example with five made-up counts shows how the median rule plays out. Say the five pages come back at 0, 2, 4, 9, and 60 referring domains, and the 60 belongs to a national retailer. Drop the retailer, and the median of the remaining four sits between 2 and 4. Your target is three or four referring domains to the page, not sixty, and a page with two good links and better content is already in the fight.
Aim for the middle of page one, not the top link count. You are not trying to out-link the strongest page on day one. You are trying to stop links from being the reason you lose, and the middle of page one is where that line sits.
Which Links Actually Move the Number
The links that actually move the number are links from sites that never linked to you before, on pages about your topic. Google’s guide to its ranking systems confirms PageRank “continues to be part of our core ranking systems,” and PageRank rewards independent sites vouching for you, which is why the #1 result’s referring-domain edge shows up in every study.
Referring Domains, Not Links
Referring domains are the count that matters, not total links. Your hundredth link from the same blog is worth almost nothing, while your first link from a new site is a fresh vote. When you measure the competition in the ten-minute check above, measure domains, and when you earn links, spread them across sites.
Relevance multiplies the vote, too. A link from a site your customers read moves you further than a technically stronger link from an unrelated one, and it can send you a buyer on top of the ranking. When you weigh two link opportunities, the one that could send a real customer is almost always the one Google values more.
Links That Google Cancels
Paid links, link swaps, and private blog networks count for nothing in your number and can count against it. Google’s spam policies list buying or selling links that pass ranking signals, excessive link exchanges, and automated link programs as link spam, and its systems are built to discount them. The money you spend on buying backlinks mostly buys links Google ignores.
The flip side is that a few spammy links pointing at you do not lower your number either. Google discounts them the same way, which is why toxic backlinks are mostly a tool scare and the disavow file stays empty on every site I run.
How to Close the Gap Once You Know It
You close a backlink gap of a few referring domains with internal links first and two or three earned links second, and the internal links usually cover half of it. Ahrefs’ same study measured internal links at a 0.117 correlation with rankings, a little under half the weight of referring domains, and internal links are the ones you control this afternoon. A product page with links from the homepage, its collection, and three blog posts behaves like a page with a couple more referring domains than it has.
After that, the earned links come from three places on nearly every store I work on. The brands you stock keep “where to buy” pages and will list you if you ask. Local and trade press write roundups of stores in your niche every year and need names. And a page with original numbers, a comparison table, or a real test gets cited by the writers who cover your category, which is the whole method behind the links Fieldsheer and Exclusive Beauty Club earned.
Spend the first week on internal links and the next month on three earned links, in that order. A gap of three domains closes in a quarter that way, and the page keeps the ranking once it gets there, since nothing in the plan is rented.
The Order I Do It In for Shopify Stores
The order I use for Shopify stores is keywords first, pages second, internal links third, and backlinks last, and the backlinks usually show up on their own by then. Most SEOs start with an outreach campaign. I start with Search Console and a list of keywords where the median referring-domain count is one I can reach this quarter.
From there, the page has to earn its spot before a link can help it. For Ergomotion, a title tag rewrite and a hub-and-spoke navigation put the Ascend bed at #2 for “hi low adjustable bed” above medical suppliers, and total sales rose 103% in peak season with no link building at all. The internal links did the lifting that most people assume needs backlinks.
Then the rankings earn the links. For Fieldsheer, a buying guide hit #1 for “best heated jackets for women” within two weeks of publishing, and in March 2026 Travel + Leisure named the brand Best Overall for Women and linked the post. That one link, earned with zero outreach, outweighs a thousand paid placements, and sales doubled from $20.7K to $42.2K year over year.
Rank the page first, and the backlinks you need to hold the ranking tend to arrive on their own. Writers cite what already ranks, since that is where they look when they need a source.
The same play is what I mean by earning backlinks without outreach: statistics pages, original comparisons, and buying guides that writers reach for. It is also the core of my Shopify SEO services, where link building is the last line of the plan, not the first.
How Many Backlinks Does a New Shopify Store Need?
A new Shopify store needs zero backlinks to rank for its first long-tail keywords and somewhere around 10 to 20 referring domains before the mid-size terms in its category start to open up, in my experience across the stores I run. The first handful come from places that already know you: suppliers, local press, the brands you stock, and the industry directories that list every store in the niche.
Just know that the number is a floor for the domain, not a target for every page. Once the store has a few dozen referring domains, most pages rank on content and internal links alone, and the backlinks you chase from then on go to the two or three money pages where page one is heavily linked.
Also, the first 20 are the hardest, since nobody links to a store with no rankings. Publish the buying guides and comparison pages first, pick the keywords where the median is zero, and let the early rankings give writers a reason to cite you. The second 20 come faster than the first.
The store-level number also matters more for AI answers than for Google. ChatGPT and Gemini lean on brand mentions more than backlinks when they decide whom to recommend, and a mention with no link still counts there.
Quick Questions About Backlink Counts
How Long Do Backlinks Take to Work?
Backlinks take about four to twelve weeks to show up in rankings, in my experience, since Google has to crawl the linking page, recrawl yours, and re-score the query. A link from a page Google crawls daily lands faster than a link from a page it visits monthly. Judge a link at eight weeks, not two.
Is 100 Backlinks a Lot?
One hundred backlinks is a lot for one page and a small number for a whole store. The figure only means something next to the page-one median for the keyword, and 100 links from 3 domains is weaker than 10 links from 10 domains. Count domains, then compare.
Do You Need Backlinks for Every Page?
You do not need backlinks for every page, and most pages on a ranking store have none. Backlinko’s 11.8 million-result study found about 95% of pages have zero backlinks, and the pages that rank without them do it on internal links and content. Reserve the link work for the two or three money pages where the page-one median is above zero, and let the rest ride on the domain.
Do Links to the Homepage Help Product Pages Rank?
Links to the homepage help product pages rank a little, through the internal links that pass the strength down, and far less than a link straight to the product page. Google’s ranking systems score the page, not the domain, so a link that points at the page you want to rank is worth several that point at the front door.
Want Your Real Number Instead of a Guess?
Forget universal backlink counts. Measure the page one you are trying to crack, count referring domains, aim for the median, and pick keywords where that median is small enough to reach this quarter. Then rank the page, and let the links follow.
If you want the shortcut, book a call and I will pull your backlink profile next to your top three competitors and show you which keywords you can win with the links you already have. If it turns into a bigger project, my Shopify SEO services pick up where the call leaves off.
