Link Building Budget Calculator: What to Spend (Free)

This calculator recommends a monthly link building budget based on your stage, ARR, category competitiveness, and authority position. The output is a recommended range with a breakdown of where the spend should go — how much to traditional link acquisition, how much to digital PR, how much to AEO/GEO work, how much to entity authority infrastructure. The math is built around benchmark data from 200+ B2B SaaS companies in our 2026 industry report, adjusted for the specific dynamics of your inputs.

The inputs you need

Current ARR (annual recurring revenue). Use the most recent quarter’s run rate × 4. This anchors what’s economically defensible as a marketing investment. Funding stage. Pre-seed, Seed, Series A, Series B, Series C, Series D+, bootstrapped profitable. Each stage has different capital availability and growth expectations. Category competitiveness. Pick low / medium / high based on whether your top 10 ranking competitors have DR 40, 60, or 80+ average. Use Ahrefs to check. Current authority position. Your domain’s Ahrefs DR or Semrush AS score. Primary goal: rank for category head term, dominate buyer-intent commercial queries, build AI citation share, capture vertical-specific queries, or general organic growth.

The recommended budget ranges by stage

The calculator outputs a stage-adjusted recommended monthly range. Typical guidance:

Pre-seed / Seed (under $500K ARR): $0-2,500/month. Most pre-seed SaaS should not be spending on link building yet. Focus on product-market fit. If you’re spending, focus on free tactics — Reddit/Quora presence, founder LinkedIn building, content publishing on your own site. Paid link building has diminishing returns at this stage.

Seed ($500K-$2M ARR): $1,500-4,000/month. Productized vendors (FATJOE, Loganix) work at this budget. Focus on foundational schema, llms.txt, comparison content. Hire a strategic specialist when budget allows but $3K can be productively spent on tactical fulfillment.

Series A ($2-10M ARR): $5,000-10,000/month. Specialist managed service tier. Mix of mid-tier publication backlinks, comparison content, digital PR pitching, AEO/GEO setup. Pipeline impact starts compounding within 6-9 months.

Series B ($10-25M ARR): $10,000-20,000/month. Full managed authority program. Tier-1 publication mentions, comprehensive AEO/GEO, entity authority work, founder PR. Authority compounding becomes structural advantage.

Series C+ ($25M+ ARR): $20,000-50,000+/month. Enterprise managed authority program with dedicated strategist, custom tooling, board-level reporting. Goal is category dominance in both Google and AI engines.

How category competitiveness changes the math

The base recommendations above assume medium-competition categories. Adjust as follows:

Low competition (emerging categories, niche verticals): 60-70 percent of the base budget can capture similar outcomes because competitive intensity is lower. Often the right answer is to invest the freed-up budget into first-mover content velocity rather than reducing total spend.

Medium competition (typical established B2B SaaS categories): Base recommendations apply.

High competition (CRM, project management, sales automation, marketing automation): 130-160 percent of base budget is realistic. The competitive intensity means link building must compete harder against well-funded incumbents with established authority.

How the calculator allocates spend

The output breaks the recommended budget into four allocation buckets:

Traditional link acquisition (40-50 percent of total). Guest posts, niche edits, contextual placements on category-relevant publications. The fulfillment work that historically defined link building.

Digital PR and brand mention seeding (25-35 percent). HARO/Connectively responses, tier-1 publication pitching, podcast guest placements, expert quotes. The work that builds entity authority and feeds AI engine training data.

AEO/GEO and AI search optimization (15-20 percent). Schema implementation, direct-answer rewriting, llms.txt, Wikidata, AI citation tracking, monthly prompt audits. The newer discipline that becomes more important every quarter. See our AEO guide.

Strategy, measurement, and reporting (10-15 percent). The senior strategist time, monthly reviews, pipeline attribution work, and quarterly strategy adjustments. This bucket gets cut first when budget is constrained but actually drives the highest ROI per dollar.

Three example budget recommendations

Example 1: Series A SaaS, $4M ARR, medium-competition category, DR 22. Output: $5,000-7,500/month recommended. Allocation: $2,500 traditional links, $1,750 PR, $1,250 AEO/GEO, $750 strategy. Expected outcome: 40-60 percent organic traffic growth in 12 months, foundational AI citation appearance.

Example 2: Series B SaaS, $18M ARR, high-competition category, DR 48. Output: $15,000-22,000/month recommended. Allocation: $7,500 traditional links, $5,500 PR, $3,500 AEO/GEO, $2,000 strategy. Expected outcome: 70-100 percent organic traffic growth in 12 months, regular AI citation appearance for category queries.

Example 3: Bootstrapped profitable SaaS, $3M ARR, emerging category, DR 35. Output: $3,500-5,500/month recommended. Allocation: $1,500 traditional links, $1,500 PR (first-mover advantage in emerging category), $1,000 AEO/GEO, $500 strategy. Expected outcome: category authority position within 12-18 months given low competition.

When the calculator’s recommendation is wrong for you

The calculator assumes you’re trying to grow organic as a primary or important channel. If organic is genuinely tertiary in your growth model (e.g., you’re product-led with viral growth and use marketing only for brand), the recommendation will be too high for your actual strategic needs.

The calculator also assumes execution competence. Spending $20,000/month on a generalist agency that doesn’t understand SaaS will produce worse ROI than spending $10,000/month on a specialist who does. Budget recommendation is necessary but not sufficient — execution quality matters more than absolute spend.

And the calculator can’t account for category timing. If your category is being disrupted by AI engines absorbing your top-of-funnel buyers right now, you may need to over-invest in AEO/GEO relative to the recommendation to avoid losing share permanently to faster-moving competitors.

Frequently asked questions

Is the recommendation what we should actually pay an agency?

It’s the recommended total monthly investment, which is what agencies typically quote. Agencies bundle execution + strategy + tooling into their monthly fee.

What if my recommended budget is more than I can afford?

Start with 50-70 percent of the recommendation. You’ll get partial outcomes but you’ll build foundational authority that compounds. Better to start partial than to skip the channel entirely.

How does this compare to industry benchmarks?

The calculator’s medians map closely to the benchmark data in our State of SaaS Link Building report — see the report for detailed pricing distributions across the sample.

Should I budget more for AI search work?

Probably yes if your category is research-heavy (developer tools, technical SaaS, enterprise software). The calculator’s 15-20 percent allocation is a baseline; push to 25-30 percent if AI engines are clearly absorbing your top-of-funnel.
