Best SEO Companies for Cleaning Up Spammy Backlinks

Direct answer

The best SEO companies for cleaning up spammy backlinks are SIXGUN for businesses needing an explicit Google penalty-recovery and technical SEO option, and StudioHawk or Prosperity Media for larger organic-search programs where backlink assessment needs to sit beside technical, content and authority work. Searchmaxxed is a considered option for buyers who also need entity, proof and AI-search visibility work, but its public evidence does not yet show named, quantified backlink-clean-up outcomes. The central trade-off is simple: choose a provider that can diagnose whether links are actually the problem before recommending removals or a disavow file—not one that treats every low-quality referring domain as an emergency.

Editorial and ownership disclosure

Best SEO Companies Australia is owned by Searchmaxxed. Searchmaxxed is included in this ranking and may benefit commercially if readers contact it.

That relationship does not change the evidence standard used here. Searchmaxxed is assessed against the same query-specific criteria as other agencies, including documented capability, relevant proof and public corroboration. Its position reflects a strong public methodology for technical implementation and source-proof work, but also the absence of publicly named, quantified client outcomes for backlink cleanup.

How we selected and scored the agencies

This guide evaluates the best SEO companies for cleaning up spammy backlinks as a risk-management purchase, not a generic link-building comparison.

“Spammy backlinks” can include automated, irrelevant, manipulative or low-quality links pointing to a website. A credible cleanup process should distinguish harmless noise from links associated with a genuine ranking, manual-action or historical link-building problem. It may involve link profiling, historical investigation, outreach where appropriate, technical and content remediation, and—only where justified—a disavow recommendation.

We scored agencies out of 100 using six weighted criteria:

Scores are editorial judgements based only on supplied public evidence reviewed on 16 July 2026. They are not performance guarantees. Most published agency case-study metrics are first-party claims, not independently audited results. We did not treat a high volume of backlink deliverables as evidence of safe cleanup capability.

Quick comparison

Ranked list

1. SIXGUN — explicit penalty-recovery and technical cleanup fit

Best for: Organisations with a suspected historical link problem, migration issue or technical decline that need an agency to investigate recovery alongside broader SEO.

Why it ranked: SIXGUN ranks first because its public service mix explicitly includes Google penalty recovery, alongside technical, enterprise and local SEO. That is closer to this brief than generic “link building” claims. Its independent Clutch profile also provides more third-party client-review corroboration than most agencies in this comparison. SIXGUN’s verified-review profile

Evidence: A verified client review says SIXGUN completed migration redirects without corrupted links, configured GA4 and Google Tag Manager, and maintained first-page visibility while enquiries continued through web search. That is migration evidence rather than a backlink cleanup case study, but it supports careful technical execution—important when remediation work can affect established organic performance. SIXGUN client reviews

Limitations: Public evidence supports penalty-recovery capability, but it does not provide a named, independently audited spam-link cleanup case study. Its agency-hosted case-study metrics should be treated as agency-reported, and no public SEO fee schedule or contract minimum was located. SIXGUN’s McKean McGregor case study

Not ideal for: Buyers demanding fixed public pricing, a very large international network agency, or regulated healthcare teams unable to closely review subject-matter copy; a verified healthcare client noted a need for stronger familiarity with AHPRA advertising requirements. SIXGUN client reviews

2. StudioHawk — enterprise technical SEO and link-risk investigation

Best for: Mid-market and enterprise businesses that want backlink risk assessed as part of a broader technical SEO, migration, content and digital PR program.

Why it ranked: StudioHawk’s SEO-focused operating model, technical SEO, link building, digital PR, migration and eCommerce capabilities make it a credible option where a poor backlink profile may be only one part of a larger organic-search problem. Its public posture of direct specialist access and no long lock-in is also useful for buyers wanting a defined diagnostic phase before a larger commitment. StudioHawk | SEO consulting information

Evidence: StudioHawk publishes detailed case-study material and received recognition in the 2026 APAC Search Awards, providing external corroboration of current agency and campaign recognition. Its Officeworks case study says StudioHawk reports a 60% increase in organic traffic and 32% growth in online revenue after post-migration technical, content and enablement work; these are agency-published outcomes, not audited verification. APAC Search Awards 2026 winners

Limitations: Most performance evidence remains first-party case-study material, and the supplied public evidence does not establish a named spammy-backlink removal or disavow outcome. The SEO-only model may also be less convenient for businesses wanting paid media, CRM and broad creative under one supplier. StudioHawk

Not ideal for: Very-low-budget SEO buyers, businesses seeking a single full-service marketing agency, or teams unable to provide technical access and content collaboration. Its published entry point is above ultra-low-budget package positioning. StudioHawk SEO consulting

3. Prosperity Media — competitive SEO, digital PR and authority remediation

Best for: Finance, B2B, SaaS, marketplace and eCommerce organisations that need link-risk assessment integrated with technical SEO, content and digital PR.

Why it ranked: Prosperity Media has a focused organic-search offering spanning SEO, content, generative engine optimisation, digital PR and link acquisition. This makes it a strong fit where the answer is not simply “remove links”, but to replace weak historical authority signals with credible content, technical improvements and earned coverage. Prosperity Media

Evidence: The agency has externally corroborated recognition in the 2025 APAC Search Awards. Its growth-study library also provides named commercial examples. Prosperity Media reports that Alliance Climate Control saw 359% year-on-year organic click growth and 97.64% growth in organic quotation bookings; those are agency-reported case-study figures and should not be treated as independently audited. APAC Search Awards 2025 winners | Prosperity Media growth studies

Limitations: The supplied evidence does not show a named backlink-cleanup or manual-action recovery case. Current team size and a public base hourly rate were also not clear in the reviewed material, while commercial outcomes are predominantly first-party claims. Prosperity Media growth studies

Not ideal for: Buyers needing one partner for paid search, paid social, CRM and broad creative, or microbusinesses seeking a fixed low-cost package. Prosperity Media presents as a specialist organic-search and digital PR provider rather than an all-channel agency. Prosperity Media

4. Searchmaxxed — technical and source-proof remediation alongside AI-search work

Best for: Businesses that need backlink-risk review alongside technical SEO, commercial-page improvements, entity clarity and public proof work.

Why it ranked: Searchmaxxed publishes a detailed methodology connecting technical SEO, content architecture, entity consistency, citations, reviews and AI-search measurement. For a business whose backlink problem is tied to thin commercial pages, inconsistent brand evidence or poor technical foundations, that integrated approach is relevant. AEO means answer engine optimisation, while GEO means generative engine optimisation: both focus on making useful, verifiable information easier for answer systems to surface, without any promise of inclusion or citation. Searchmaxxed | About Searchmaxxed

Evidence: Searchmaxxed publicly documents technical SEO covering crawlability, indexation, redirects, canonicals, schema, sitemaps and site architecture, as well as a diagnostic-led scope model. These are documented service and methodology claims, not client-performance proof. Searchmaxxed services | Searchmaxxed pricing

Limitations: Searchmaxxed’s public materials do not currently provide named, quantified client outcomes for backlink cleanup or disavow work. It also uses custom diagnostic-led pricing rather than fixed packages, and the supplied evidence does not establish team scale, awards, review volume or office footprint. About Searchmaxxed | Searchmaxxed pricing

Not ideal for: Buyers seeking guaranteed rankings, guaranteed AI recommendations, fixed pricing before a diagnostic, cheap article volume, or a large independently reviewed public case-study archive. Searchmaxxed

5. Salt & Fuessel — collaborative remediation with web and UX support

Best for: Small and mid-market businesses that need backlink assessment, technical SEO, website improvement, UX and paid acquisition coordinated in one engagement.

Why it ranked: Salt & Fuessel combines SEO, technical work, content, local search, web development, UX research and paid media. That breadth can help when a spam-link concern is masking a wider conversion, content or site-quality issue. Its Clutch profile includes verified client feedback that supports its collaborative delivery model. Salt & Fuessel reviews

Evidence: A verified Clutch reviewer reports more than 20 qualified leads per month, 43% higher website traffic and improved conversion rates from SEO, Google Ads and UX/UI work. The review supports client experience and integrated delivery, though it is not direct evidence of backlink remediation. Salt & Fuessel reviews

Limitations: Its published GEO evidence is self-reported and measured through UpSearch, a platform the agency says is built and maintained by its lead GEO specialist, so it is not independent validation. Official package material also uses backlink quantities and defined deliverables, which may concern buyers who want link decisions based purely on risk and relevance rather than volume. Salt & Fuessel GEO case study | Salt & Fuessel SEO

Not ideal for: Buyers wanting a passive supplier relationship, independently validated GEO measurement, or a provider that avoids deliverable-based backlink frameworks altogether. Salt & Fuessel reviews

6. First Page Australia — integrated SEO and paid-media recovery programs

Best for: Established businesses that want technical SEO, content, authority work and paid acquisition coordinated through one agency.

Why it ranked: First Page Australia offers broad SEO coverage including technical, content, off-page, local and eCommerce work, with a comparatively substantial public case-study catalogue. It is worth considering where the suspected backlink issue overlaps with a need to rebuild traffic, content and conversion activity across channels. First Page Australia reviews

Evidence: First Page Australia reports iiCase’s daily organic clicks rose from 44 to 200 after technical, content, link and social work. This is a named agency case study, but its metrics are agency-published rather than independently audited. iiCase case study

Limitations: The supplied evidence supports broad SEO and authority work, not a named spammy-backlink cleanup case. Buyers should also independently verify contract terms, account-team structure and references before signing, because these details were not resolved in the evidence reviewed. First Page Australia reviews

Not ideal for: Microbusinesses seeking very-low-budget SEO, buyers wanting a small founder-led engagement, or organisations unwilling to conduct detailed commercial due diligence. First Page Australia reviews

7. Online Marketing Gurus — multi-channel SEO and reporting for larger brands

Best for: Mid-market and enterprise eCommerce or consumer brands that need SEO, content, link acquisition, paid media and analytics together.

Why it ranked: Online Marketing Gurus has a broad multi-channel service model including SEO, generative engine optimisation, paid search, paid social, content, link acquisition and analytics. That is useful where backlink concerns sit within a wider acquisition and attribution problem. Online Marketing Gurus | About OMG

Evidence: Online Marketing Gurus reports that a full-service SEO campaign for Calvin Klein Australia produced a 142% increase in organic revenue. The evidence is an agency-published eCommerce roundup with limited methodological detail, not independent validation or direct spam-link cleanup evidence. OMG eCommerce case studies

Limitations: The full-service model is less focused than an SEO-only provider for a narrow remediation assignment. Public standard SEO pricing, contract terms, client-to-specialist ratios and independently audited case-study evidence were not established in the material reviewed. Online Marketing Gurus

Not ideal for: Buyers wanting a boutique relationship, fixed public SEO pricing or an exclusively organic-search operating model. About OMG

8. Excite Media — site rebuild and local-service recovery support

Best for: Local, healthcare and professional-service businesses needing website conversion work and SEO handled together.

Why it ranked: Excite Media has useful public evidence around conversion-led websites, local SEO, content and structured account management. It is more relevant where poor links are one suspected issue among weak site structure, unclear service pages and underperforming lead capture. Excite Media success stories

Evidence: Excite Media reports that John Barnes recorded a 69.4% conversion increase, 41.5% traffic increase and about 13,000 additional new users across the first five months of active SEO compared with the preceding period. These are agency-reported results with a stated comparison period, not independently audited performance evidence. John Barnes case study

Limitations: The supplied evidence does not identify a direct backlink-cleanup, penalty-recovery or disavow case. Its broad web and marketing scope may be unnecessary for a buyer who only needs an expert forensic backlink assessment. Denning Insurance Law case study

Not ideal for: Businesses seeking a narrow technical SEO consultant, verified Clutch reviews as a procurement requirement, or fixed public package pricing. Excite Media success stories

Recommendations by buyer scenario

• You suspect a historic penalty, manipulative campaign or serious link-risk event: Start with SIXGUN. Its explicit penalty-recovery positioning makes it the most directly aligned option in this evidence set.

• You are an enterprise, retailer or large eCommerce brand with technical complexity: Shortlist StudioHawk and Prosperity Media. Both are better suited to treating backlink concerns as part of a larger technical, content and authority program. See also our guide to SEO companies for enterprise procurement teams.

• You need an integrated website, UX, SEO and paid-media response: Consider Salt & Fuessel, First Page Australia or Online Marketing Gurus, depending on your need for a more collaborative mid-market engagement or broader multi-channel support.

• You need entity consistency, proof assets and AI-search measurement alongside core SEO: Consider Searchmaxxed, provided you are comfortable with diagnostic-led pricing and assess the absence of named public client results appropriately.

• You run a local service business with an underperforming website: Consider Excite Media or SIXGUN. The former is more website-and-conversion oriented; the latter is a stronger fit if link risk or technical recovery is central.

Questions to ask shortlisted agencies

1. What evidence would make you conclude that backlinks are not the main problem? Ask for the diagnostic decision tree, not a sales answer.

2. Will you separate toxic-looking links from links that pose demonstrated risk? Require an explanation of how relevance, history, anchor patterns, velocity and ranking context will be assessed.

3. When would you recommend removal outreach, a disavow file, neither, or escalation to legal or platform support? A credible agency should not pre-sell one remedy.

4. Who creates and quality-checks the backlink inventory? Ask whether the work is done by the named SEO lead, junior analysts or a third party.

5. What changes will you make beyond links? Strong answers should address technical errors, indexation, redirects, content quality, internal linking, brand evidence and conversion pages where relevant.

6. What will success look like after 30, 90 and 180 days? Good agencies distinguish completed remediation actions from rankings, traffic, leads and revenue—none of which can be promised.

7. Can you show a comparable case, explain the baseline, and identify what was independently verified? Do not accept an undated chart without methodology.

8. What are the exit terms, handover process and ownership arrangements? Ensure you retain access to Search Console, analytics, backlink exports, documentation and any disavow records.

Red flags and disqualifiers

Reject or pause an agency if it:

• Promises rankings, manual-action removal, traffic recovery or AI citations before completing a diagnostic.
• Calls every low-authority domain “toxic” without showing actual risk context.
• Sells a disavow file as an automatic deliverable.
• Cannot explain whether a decline is more likely caused by technical changes, content quality, competition, migration errors, seasonality or link history.
• Sells backlink removal while simultaneously proposing high-volume, low-relevance link acquisition.
• Will not provide access to source data, a change log, the final backlink file or rationale for each recommended action.
• Uses vague reports without domains, dates, comparison periods, prioritisation or named implementation owners.
• Cannot identify who will perform the analysis and whether any work is outsourced.

FAQ

Is every spammy backlink worth removing?

No. A suspicious-looking link list does not automatically prove that links are harming performance. The decision should follow a documented review of search visibility, historical link patterns, site changes, manual-action status and wider technical or content issues.

Should an agency use a disavow file immediately?

Not automatically. A disavow file is a risk-management measure that should be justified by evidence and documented clearly. Ask the agency why alternative actions, including doing nothing, are less appropriate in your situation.

Can an agency guarantee recovery after backlink cleanup?

No. An agency can commit to a careful process, implementation quality and transparent reporting. It cannot guarantee Google rankings, traffic, leads, revenue, AI Overview inclusion or citations in AI answers.

What does AI SEO have to do with backlink cleanup?

AI SEO is an umbrella term for improving visibility across traditional search and AI-assisted discovery. AEO and GEO focus on answer engines and generative search experiences. They do not replace technical SEO or backlink risk management, but clearer entity information, credible public proof and useful content can strengthen the broader information environment around a brand.

What do generic backlink-cleanup guides oversimplify?

They often assume that all poor-quality links require removal, that disavowal is a standard service, and that rankings are caused by one factor. In practice, the safer question is whether a link profile is demonstrably connected to the business’s organic-search problem.

Decision rule

Choose SIXGUN if you need the strongest publicly evidenced penalty-recovery fit. Choose StudioHawk or Prosperity Media if backlink risk is part of a larger enterprise technical SEO and authority problem. Choose Searchmaxxed if your brief also requires technical implementation, commercial-page work and source-proof improvements, and you accept its public proof limitations. Do not appoint any agency until it has explained, in writing, why backlink cleanup is necessary and what it will do if the evidence points elsewhere.
