How Many Backlinks Do I Need? Estimate It From Competitors

There is no universal number of backlinks. What exists is the distance between your page and the pages already on Google's first page for the same search. To estimate it, count how many different sites (the referring domains) link to each competitor, calculate the median and compare it with your page. If you are just starting out, read what backlinks are first.

Quick summary

Your link target comes from the competition for the search you want to win, not from a general rule like "50 links" or "100 links".
Count referring domains (distinct sites), not the total number of links: fifty links from the same site are a weaker signal than five different sites.
The method: list the top 10 results, drop the giants that are not comparable, note the referring domains of each URL and use the median as your target.
Quantity without quality does not solve anything: links from sites with no audience or off-topic sites do not count.
Pace matters as much as the total. Split the target into quarters and track the effect in Google Search Console.

Is there a right number of backlinks?

No. Google does not publish a minimum number of links, and third-party tools cannot see Google's internal ranking data. What you can observe is correlation. According to an Ahrefs study from December 2023 covering about 14 billion pages in the company's own index, 96.55% of pages get no traffic from Google, and pages with more referring domains tend to get more traffic.

The study itself warns that correlation does not prove causation. It also notes that, among pages with no referring domains at all, only a small fraction gets more than a thousand monthly visits (2,997 out of about 20 million), and those that do tend to target low-competition topics. The practical reading: for easy searches a few links are enough; for competitive searches, page one usually demands many.

In plain English: picture a job opening with ten finalists, each handing in reference letters. There is no "ideal number of letters." But if the finalists have between ten and forty letters from different companies and you have two, you already know you are not in the race yet. Backlinks are the letters, and referring domains are the different companies that signed them.

What should you count: backlinks or referring domains?

Count referring domains, meaning how many distinct sites link to the page. A single site can generate thousands of links (a footer link on every page, for example), which inflates the total without adding any variety of sources. The table shows what each metric tells you and the caveat for each.

Metric	What it measures	Use in the estimate	Caveat
Backlinks (total)	Every link received	Not very useful alone	Footers and repeated links inflate the number
Referring domains of the URL	Distinct sites linking to that specific page	Main metric for the comparison	Compare URL to URL, not to the homepage
Referring domains of the site	Distinct sites linking to any page on the domain	Shows the competitor's overall strength	A strong homepage can prop up weak pages
DR or DA	Estimated domain strength, calculated by the tool	Context: is your site weaker or stronger?	It is a third-party metric, not Google's. See how to check DA and DR
New domains per month	Acquisition pace	Defines the quarterly plan	Needs history in the tool

For SEO professionals: always compare using the same tool for yourself and your competitors, because Ahrefs, Semrush and Moz crawl the web in their own ways and the numbers do not match each other. In Search Console, the Links report shows only a sample of your links (tables capped at 1,000 rows, grouped by root domain), so it is useful for checking your own links, not for measuring competitors.

How do you estimate it from the competition, step by step?

There are six steps, and you can do them in a spreadsheet. Do one page at a time: the target for a product page does not fit a blog article.

Pick the page and the search. Decide which of your URLs should rank and for which main query, for example "clinic management software".
List the top 10 results. Search in an incognito window and note the position, URL and type of site (blog, portal, comparison site, store, forum).
Drop what is not comparable. Giant portals, marketplaces, forums and government sites have thousands of links for reasons you will not replicate. Mark them as "out of the count."
Record the referring domains of each URL in a backlink analysis tool (if you do not have access, see the options for free tools to analyze backlinks).
Calculate the median of the remaining URLs. Also calculate the median of positions 4 to 10 (your entry target for page one) and of positions 1 to 3 (your target to compete for the top).
Subtract what you already have. The difference between the median and your URL's referring domains is the distance. Adjust for quality and turn it into a monthly plan.

To find out where competitors' links come from and which ones you can win, the next step is the link gap analysis.

Hypothetical example: calculating the target for one page

Hypothetical example, with invented numbers used only to illustrate the calculation. Imagine the search "clinic management software" and a page of yours with 3 referring domains.

Position	Type of site	Referring domains of the URL	In the count?
1	Large portal	410	No (out of scale)
2	Software blog	38	Yes
3	Comparison site	27	Yes
4	Niche blog	19	Yes
5	Software blog	14	Yes
6	Agency site	11	Yes
7	Niche blog	9	Yes
8	Q&A forum	60	No (forum)
9	Niche blog	6	Yes
10	Agency site	4	Yes

With the eight remaining results (4, 6, 9, 11, 14, 19, 27 and 38), the median is 12.5. Looking only at the positions 4 to 10 that stayed in the count (4, 6, 9, 11, 14 and 19), the median is 10: that is your entry target. Positions 2 and 3 (27 and 38) point to the top target, between 27 and 38.

Your page has 3, so the distance to the entry target is 7 domains. Over a four-month plan, that is about 2 new domains per month, with the caveat that the number only holds if the links come from relevant sites with real audiences. To compete for the top, the math rises to 24 to 35 domains, and it is worth asking whether the return justifies the investment.

When are a few links enough, and when are they not?

A few links are enough when the search is specific, page one is made of small sites and your content is clearly better. You need many when the search is broad and commercial, the results page is dominated by portals and your site is new. The table summarizes the factors that move the target the most.

Factor	Tends to need fewer links	Tends to need more links
Type of search	Specific question, long tail	Broad commercial term
Page one	Small blogs and niche sites	Portals, marketplaces, big brands
Your site	Long history, already has links and traffic	New domain, no history
Content	More complete and current answer than competitors	Similar to what already exists
Internal links	Page well connected to the rest of the site	Orphan or buried page

For SEO professionals: look at domain age and pace, not just the stock. Hypothetical example: a competitor with 38 domains accumulated over six years acquired about 6 per year on average. If you want to catch up within a year, you are asking for a pace far above theirs, and that stands out from a natural link profile. The new referring domains over time report in backlink tools shows this pace. To understand what a healthy profile looks like, see natural backlink profile.

Are ten bad links worth more than two good ones?

No. Quality outweighs volume, and low-quality links can even bring risk. Google defines link spam as links created mainly to manipulate ranking, and its spam policy expressly mentions buying or selling links for that purpose, along with optimized anchors in guest posts and press releases distributed on other sites.

In practice, a good link comes from a site that would exist even without selling links, with real readers, in a text about your topic. Google also states, in its SEO starter guide, that links from other sites happen naturally over time and that promoting your content helps that process. To evaluate a site before accepting a link, use the checklist in how to identify quality backlinks.

In plain English: a compliment is worth more when it comes from someone who knows the subject and has readers. Ten compliments from strangers who praise anything do not convince anyone.

What pace should you follow, and what does it cost?

Follow a continuous, gradual pace, without spikes. Google does not publish an ideal pace, so use what your competitors acquire per month as a reference and split the target into quarters. After each batch, compare the page's impressions, clicks and position in Search Console before buying or earning more.

On cost, there are two paths: earn links with content and outreach (cheap in money, expensive in time) or pay for placements. In the example above, closing the 7-domain gap with paid links from Contentor would cost $343 (7 links at $49 each in the standard niche, with no volume discount, sold in packages of 1, 3, 5 or 10). Contentor's links are placed on Brazilian, Portuguese-language sites, so they make the most sense if your audience reads Portuguese. Remember that Google considers links bought to influence ranking a violation of its spam policies when they are not qualified with rel="sponsored" or rel="nofollow"; understand the risk in is buying backlinks safe? and compare price ranges in how much a backlink costs in Brazil.

Frequently asked questions

How many backlinks do I need to rank first on Google?

There is no fixed number. You need to get close to the top target for your search (the median of positions 1 to 3, without outliers) and have a page that is clearly better than theirs. Even then, no one can guarantee the first position, because Google uses many other signals besides links.

Is 100 backlinks a lot or a little?

It depends on how many different sites they represent. One hundred links from five sites count as five referring domains, which is little. One hundred links from one hundred relevant sites is a robust profile for most mid-competition searches, but it can still fall short for highly competitive terms.

Do backlinks from the same site count several times?

As a signal of variety, no: the tool groups them all into a single referring domain. Google does not detail how it weighs repeated links from the same site, so the practice is to prioritize new, relevant sites instead of insisting on the same one.

How many backlinks does a new site need?

Fewer than it seems at first, because the first step is to be discovered and have content that answers the query well. Aim first at low-competition searches, where the target is a handful of domains, and grow gradually. The schedule in link building for new sites details the pace.

Can you rank with no backlinks at all?

Yes, for low-competition searches, especially on sites that already have authority and good internal links. For competitive commercial searches, the common observation among professionals, cited in the Ahrefs study, is that it is very hard to reach page one without backlinks. It is an observation, not a Google rule.
