How many backlinks do you need? What 10 campaigns showed

How many backlinks do you need? For most established B2B websites, the answer is fewer than you might expect, placed on the right pages. In 9 of our 10 campaigns, 6 to 37 links over three to eleven months held or raised authority. A manufacturer site that started with almost no authority needed 276 links over two years. That total also includes quick-win links from the company’s two other websites.

The right number depends on three things: your starting authority, the strength of your competitors and your time frame. If you are asking “how many backlinks do I need?”, this article shows what we saw in each campaign.

What our 10 campaigns showed

The table below compares 10 link building campaigns we ran between May 2024 and September 2026. Each client is described by sector, not by name. All figures are from Ahrefs for the dates shown.

Domain rating (DR) is Ahrefs’ score for the strength of a site’s backlink profile, on a 0 to 100 scale. Referring domains are the number of separate websites linking to a site. Traffic is Ahrefs’ estimate of monthly organic visits.

Source: Ahrefs, for each campaign’s dates. “Not claimed” means organic traffic fell during that window, so we make no traffic claim. Link counts are the number of links we placed, not the total links each site gained.

Three patterns stand out. First, link count and growth do not line up neatly. Second, the starting domain rating shapes the result more than the number of links. Third, where each link points matters as much as how many there are.

Links placed are not the same as referring domains gained

In most campaigns, referring domains grew far more than the number of links we placed. The web data platform gained about 1,940 referring domains during a campaign in which we placed 17 links.

We do not claim those extra domains as our own work. Strong sites gain links from many sources at once, such as press coverage, partners and other people’s content. Placed links add to that, and they can help key pages rank, which brings in more natural links.

This matters when you plan a budget. The number of backlinks you need to buy or earn is usually much smaller than the referring domain total you see in a tool. Judge a campaign by what happens to rankings, authority and traffic, not by a single link total.

How many backlinks do I need for my starting point?

The clearest pattern in our data is the effect of starting authority. A site with almost no links behaves very differently from a site that already has thousands.

Source: our campaign data above (Ahrefs). Pace is links placed divided by campaign months, rounded.

New or overlooked sites need volume first

A site that starts near zero has no authority to build on. The heating and insulation manufacturer started at domain rating 3 with 12 referring domains. We placed 5 links a month at first, 10 a month from April 2025, and 15 a month from June 2026.

Its domain rating reached 36 in under four months and 61 after 24 months. The new business data website followed a similar path, moving from 0 to 38 with 37 links in nine months.

Established sites need fewer, better-aimed links

At the top of the scale, each extra point is hard to gain. Ahrefs states that climbing from DR 20 to 30 takes a handful of links, while climbing from 70 to 80 can take thousands.

So for leaders, domain rating is the wrong goal. The search engine optimisation software company placed 12 links and its domain rating moved one point. Its organic traffic rose from 366,707 to 1,061,224 visits a month over the same period, with the links aimed at product pages and guides.

Your competitors set the real target

There is no universal number of backlinks, because authority is relative. Ahrefs describes domain rating as relative by design, and says a good score is whatever beats the companies you actually compete with.

Ahrefs’ own benchmark of 600 software as a service (SaaS) companies found a median domain rating of 62. The top quartile sat at 77 and the top 10% at 86. If your rivals sit in the 70s, a site at 45 needs a steady campaign, not a one-off burst.

To find your own gap, compare three numbers for you and your top three search competitors:

1. Domain rating, from Ahrefs.
2. Referring domains to the site as a whole.
3. Referring domains to the specific pages that rank for your target searches.

The third number is often the most useful. A competitor’s ranking page may have 40 referring domains while yours has 3. That page level gap is a better guide to how many backlinks you need than any site-wide average.

Where links point matters as much as how many

In almost every campaign, links went to the pages that bring in revenue, not the homepage. The digital signage company’s links went to its industry pages for gyms, retail, workplaces and hospitality.

The enterprise backup storage company is the clearest example. We placed 7 links, aimed at its guides on ransomware response and data backup. Its domain rating rose from 46 to 58, and organic traffic rose from 2,340 to 5,169 visits a month.

Ahrefs’ study of about 14 billion pages found a clear link between the number of websites linking to a page and its traffic. Ahrefs also notes that this correlation does not prove cause. In our experience, a link to a page with a clear search purpose does more than a link to a general page.

How to estimate the number for your own site

You can build a working estimate in an afternoon with Ahrefs or a similar tool. Follow these steps.

1. List your target pages. Choose 5 to 10 pages tied to revenue, such as product, service or comparison pages.
2. Check who ranks. For each page’s main search term, note the top five results and their referring domains.
3. Measure the gap. Subtract your page’s referring domains from the median of the top five.
4. Add the site-wide gap. Compare your domain rating with your three closest competitors.
5. Set a monthly pace. Spread the total over 6 to 12 months, so growth looks steady and natural.

This gives a range, not an exact figure. Rankings also depend on content quality, technical health and how well a page matches the search. A page with a technical problem will not rank, however many links point to it.

Quality rules we use for every link

The number of backlinks only matters if each one is worth having. Every placement in these campaigns had to meet the same standards.

• Relevant website. The linking site covers the same field as the target page.
• Real organic traffic. The site has genuine search visitors, not just a high score.
• Link inside the text. The link sits within the article, with descriptive anchor text.
• Steady pace. Links go live across months, not in one batch.

For the digital wellness app, we also checked which sites AI tools already cited. Its 10 placements sat on sites with an average domain rating of 68. Monthly AI citations rose from 10 to 151 in three months (15x).

What this means for your plan

Start with your competitors and your target pages, not with a number. A new or overlooked site may need hundreds of links over two years. An established site may see clear gains from 6 to 23 well-aimed links over a year.

Frequently asked questions

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

There is no fixed number. Compare the referring domains of the pages that already rank for your search with your own page. The gap is your best guide.

How many backlinks should I build each month?

In our campaigns, the pace ranged from about 1 a month for established sites to 15 a month for a manufacturer site with almost no authority. Steady growth over months is better than one large batch.

Do I need more backlinks if my domain rating is high?

Usually you need fewer links, aimed at specific pages. Domain rating moves slowly at the top of the scale, so measure rankings and traffic to target pages instead.

Is one high-authority backlink worth more than many weak ones?

Often, yes. Relevance, real traffic and placement inside the article text matter more than volume. In our data, 7 well-aimed links coincided with a 12-point domain rating gain.

How long before new backlinks have an effect?

It varies. One manufacturer site in our data, starting with almost no authority, reached domain rating 36 in under four months, while traffic took longer to follow.

Do backlinks still matter for AI search?

In our experience, yes. Links on sites that AI tools already cite can lead to more brand mentions in AI answers, as our digital wellness app campaign showed.
