How to Choose a SaaS Link Building Agency: 12 Questions to Ask

Ask twelve questions before you sign anything, and make the first one this: can I see the placement sites before you publish? Agencies with real editorial relationships say yes without hesitation. Agencies reselling inventory or running private networks deflect, stall, or offer samples "after onboarding." That single answer tells you more than any case study PDF they send.

Choosing a link building agency is a high stakes decision for SaaS. The wrong agency burns budget on links Google ignores or penalizes. The right one compounds into rankings that drive demos for years. The March 2024 spam policies made this choice sharper: scaled content abuse, site reputation abuse, and expired domain abuse are now explicit violations, so an agency selling PBN links or parasite placements is selling what Google defines as spam.

Key takeaways

• The highest signal question is pre publication visibility of placement sites. A yes means real outreach. A no means walk away.
• Real outreach plus real content plus real QA has a cost floor. Anything far below $1,000 per month cannot be manual editorial work at SaaS quality.
• Take 5 to 10 sample links and verify them yourself in Ahrefs. Ten minutes per link exposes most bad actors.
• Get link replacement and indexation terms in writing. Verbal guarantees evaporate when links get removed.

The 12 questions

1. Can I see the placement sites before you publish?

This is the question that ends most bad sales calls. Legitimate agencies show you target sites during outreach or before content goes live, because their value is the relationship and the pitch. Agencies that refuse are usually placing on their own network, reselling the same inventory to every client, or buying posts from vendors and marking them up. If the answer is anything softer than yes, you have your answer about the agency.

2. Show me 5 to 10 recent live links from SaaS clients

Not screenshots. Not a logo wall. Live URLs you can open and inspect. Then do what the London Daily News vetting guide recommends: verify each one yourself in Ahrefs. Check that the page has real organic traffic, read the content around your link, and look at the page's other outbound links. A DR 63 domain with zero traffic and outbound links to casinos is not a quality placement, no matter what the report says.

3. What is the average DR and organic traffic of your placements?

DR alone means little since the March 2024 updates. Practitioners now screen on organic traffic and topical relevance first, after finding DR 60+ domains with no traffic being sold as premium inventory. Push for both numbers: average DR 60+ is a reasonable SaaS target, but only alongside real traffic in your niche. An agency that quotes DR without traffic is either outdated or hiding something.

4. Walk me through exactly how you acquire links

You want a concrete process: prospecting criteria, outreach volume, content creation, QA checks, and who does each step. Vague answers like "we have relationships with thousands of webmasters" or "our proprietary network" are confessions. As SaaSLinks' vetting guide notes, the phrase "proprietary network" as an answer means yes to PBNs. Real outreach is labor intensive and agencies proud of it describe it in detail.

5. What share of links points to product or feature pages versus blog content?

Most agencies default to linking blog posts because it is easier. But pipeline comes from commercial pages ranking. Ask what percentage of their placements target product, feature, comparison, or pricing pages, and how they earn editorial links to pages that are openly commercial. If they have no strategy for commercial page links, their reporting will show activity while your revenue stays flat.

6. Who actually does the work?

The strategist on your sales call is rarely the person sending outreach. Ask whether link building is done by an in house team, freelancers, or outsourced entirely, and who writes the content. One common red flag from practitioner reports: a named strategist during sales, then a generic support inbox after you pay. Get the delivery team structure in writing before you sign.

7. What happens when a link gets removed? What are the replacement terms?

Links decay. Sites redesign, pages get deleted, webmasters remove links. Honest agencies replace lost links inside a defined window, typically 6 to 12 months, and put it in the contract. The enforceable version of a guarantee is a written replacement clause plus a 30 day indexation commitment, not a promise of rankings. If replacement terms are verbal, they do not exist.

8. What does month 1, 3, 6, and 12 realistically look like?

You are testing for honesty about timelines. Realistic: month 1 is auditing and prospecting with few live links, months 2 to 3 bring the first placements, months 6 to 12 show compounding as content and links age. Anyone promising dozens of links in month one is running automation or a controlled network. Anyone promising specific ranking positions by a date is lying, because nobody controls Google's algorithm.

9. How do you stay clear of Google's spam policies?

Name the policies: scaled content abuse, site reputation abuse, and link spam, all sharpened since March 2024, plus the May 2025 extension covering manipulation of AI generated answers. Ask how their placements avoid each one. You want to hear about editorial standards, real traffic requirements, and content written for the host audience. If the agency has never heard of site reputation abuse, end the call.

10. Will I see every live URL in reporting, and can I verify indexation?

Reporting without live URLs is the oldest trick in the book. Reporting guides flag it as the top red flag: no live URL means you cannot verify the link exists or is indexed. Insist on a live link report with placement URLs, anchor text, and target pages. Then spot check indexation yourself with a site: search or Search Console.

11. How do you measure success beyond link counts and DA?

Activity metrics are easy to fake and easy to celebrate. Push for commercial reporting: which target pages moved, what happened to organic traffic and conversions on those pages, and how the agency connects links to demos, trials, or revenue. An agency that only reports links built and average DA is selling motion, not outcomes. Ask what share of their clients can tie the engagement to pipeline.

12. What are the exact pricing, contract, and cancellation terms?

Get the full commercial picture before the pilot ends: cost per link or retainer, whether content writing is included, any setup fees, minimum term, and how cancellation works. Pricing hidden until the sales call is itself a red flag noted across buyer guides. You should also ask what happens to published content and links if you cancel, because some contracts let agencies remove guest posts when you leave.

2026 pricing benchmarks

Use these numbers from LinkDoctor's agency evaluation guide and market surveys to calibrate quotes. Per link pricing runs $50 to $1,500+, which is a uselessly wide range until you segment it: the bottom end is vendor marketplace inventory, the top end is digital PR placements on major publications. Monthly retainers run $1,000 to $5,000+. Content led and PR driven link building starts around $3,000 per month.

Price is a filter, not a detail. Manual outreach, real content, and QA have a cost floor, and anything far below $1,000 a month cannot be doing editorial work at SaaS quality. That does not mean the most expensive agency is the best. It means suspiciously cheap quotes deserve the hardest questions. Our breakdown of link building costs goes deeper on what each tier actually includes.

Score yourself: the 36 point test

LinkDoctor publishes a 12 area evaluation scorecard, scored 0 to 3 per area for 36 total. The areas cover business alignment, site readiness checks, method transparency, acquisition disclosure, evaluation beyond DR, target page strategy, brand protection, team identity, campaign visibility, evidence, link monitoring and replacement, and pricing clarity. Score 31 to 36 and the agency is strong. Score 24 to 30 and investigate the weak areas. Below 24, walk away no matter how good the pitch sounded.

Run every finalist through it on the same call. The scorecard forces specificity, and specificity is what bad agencies cannot provide.

How to verify sample links in 10 minutes each

Take the 5 to 10 sample URLs and run this check. Open the page and read it: is the content genuinely useful to the host site's audience, or filler built around a link? Check the page's organic traffic in Ahrefs: real traffic means Google values the page. Scan the outbound links: if the page links to essay services, crypto casinos, or unrelated junk, the site sells links indiscriminately. Check the link's context: editorial links sit inside relevant content, not in author bios or footers. Finally, check topical fit: your SaaS tool on a gambling or recipe site is a zero relevance placement that reports well and performs poorly.

FAQ

How much should a SaaS company spend on link building?

Most SaaS companies spending seriously allocate $3,000 to $10,000 per month. Below $1,000 you are buying marketplace inventory, not outreach. Above $10,000 usually means digital PR campaigns layered on top of steady outreach.

Should I choose per link pricing or a retainer?

Retainers align incentives better for ongoing growth, because the agency invests in relationships and content. Per link pricing works for one off pushes but can incentivize volume over fit. Either way, insist on pre publication visibility and replacement terms.

How long before a new agency shows results?

Expect first placements in 4 to 8 weeks and ranking movement in 3 to 6 months. Any agency promising page one in 30 days is either lying or planning tactics that will get you penalized.

Can I just build links in house instead?

Yes, if you can hire and retain outreach talent. Most SaaS companies find the hybrid model wins: an in house strategist owning the roadmap plus an agency executing outreach. It gets you control plus capacity without the full payroll load.
