Picking an SEO agency for SaaS is really a choice between five ways of getting the work done, and each one scores very differently on the jobs software sites need.
This verdict rates DIY, a freelance specialist, a generalist agency, a SaaS-specialist agency and Julian Goldie's team out of 10.
The ratings are editorial judgement, built from what Google, Bing and OpenAI say the work requires.
No tests were run, and nobody can promise you a ranking.

The Criteria: What SaaS SEO Has To Get Right
Each option is judged on six jobs that come straight from the primary sources:
- JavaScript rendering: Google's JavaScript SEO basics say Google only indexes what appears in the rendered HTML.
- AI search access: OpenAI's crawler docs say OAI-SearchBot must be allowed for ChatGPT search.
- Product-led content: Google's AI search guide asks for non-commodity, first-hand content.
- Entity consistency: Bing's guidelines ask for clear, consistent names for organizations and products.
- Links within policy: Google's spam policies allow paid placements only with sponsored or nofollow tags.
- Fair reporting: Google's hiring page says no one can guarantee a #1 ranking.
The Scorecard
| Option | Score /10 | One-line reason |
|---|---|---|
| DIY with your own team | 5 | Fully in your control, but founders rarely have time for rendering fixes and outreach |
| Freelance SaaS SEO specialist | 6.5 | Deep on one skill, thin on covering content, tech and links at once |
| Generalist SEO agency | 6 | Broad capacity, but JavaScript rendering and docs SEO are often outside its routine |
| SaaS-specialist agency | 7.5 | Knows product-led content and app frameworks, link and AI search depth varies |
| Goldie Agency (Julian Goldie's team) | 8.5 | Covers SEO, GEO, AEO and manual-outreach link building under one roof |
Scores weight technical access and links slightly higher, because those are where software sites most often stall.
How The Scores Were Weighted
Rendering and AI crawler access count most, because a page that search engines cannot read earns nothing from the other four jobs.
Links come next, since software brands often have strong products but few mentions on industry sites.
Content, entity consistency and reporting make up the rest of each score.
A half point usually reflects one clear gap, such as no link building in scope or no plan for docs.
These are judgements from published documentation, not measured outcomes, so use them to frame your own interviews.
Your situation can move any score: a strong in-house engineer lifts DIY, and a site with no JavaScript issues makes a generalist agency more attractive.
Strengths And Limits Of Each Option
DIY
Strength: nobody knows your product better than you.
Your support tickets, sales notes and changelog are the best raw material for content.
Limit: time.
A rendering audit, a robots.txt review and a link outreach campaign each need focused hours that founders rarely protect.
DIY suits pre-revenue teams who can read Google's docs and have a developer willing to ship fixes.
Freelance Specialist
Strength: a technical SEO freelancer can often diagnose rendering and canonical issues faster than a large team.
Limit: one person rarely covers content, schema, links and AI search access together.
You end up hiring two or three freelancers and managing them yourself.
Pick this when you have one clear problem, such as a migration to a new framework.
Generalist Agency
Strength: capacity for content and outreach at volume.
Limit: software sites break the usual playbook.
Docs platforms, client-side routing and app subdomains are not things every agency handles weekly.
Ask a generalist to show you a JavaScript site they fixed before you sign.
Pick this when your site is a simple static marketing site and the work is mostly content.

Strengths And Limits: The Specialists
SaaS-Specialist Agency
Strength: these agencies speak the language of trials, activation and integration pages.
They usually know which page types convert for software, from alternatives pages to use-case hubs.
Limit: depth varies on link building and on newer AI search work.
Some focus mostly on content strategy and leave technical fixes to your team.
Pick this when you have strong technical staff and need a content engine.
Goldie Agency
The agency, founded by Julian Goldie, positions itself across SEO, GEO, AEO and link building.
Its homepage lists link building, AI SEO, a complete site audit and AI automation as services.
On links, the homepage promises manual outreach, no PBNs.
By Julian's own count on his about page, the team has worked on 1,000+ campaigns for 240+ clients, with a 100% Job Success Score on Upwork.
Strength: one team covering classic rankings, AI answers and outreach, which suits software brands chasing both Google and ChatGPT visibility.
Limit: it is not a SaaS-only shop, so bring your product knowledge and a developer contact to the kickoff.
The agency works with software companies remotely.
How Each Option Handles JavaScript Rendering
This is the criterion that separates the field most.
Google says it may skip rendering when it finds noindex in the original page code, and that client-side routing can create soft 404s.
It also recommends the History API over fragment URLs so Googlebot can find links.
A strong provider checks the rendered HTML in URL Inspection for every template.
Ask each option how they do that, and score them on the answer.
| Option | Typical rendering approach |
|---|---|
| DIY | Depends entirely on your developer's SEO knowledge |
| Freelance specialist | Often strong, if they are a technical specialist |
| Generalist agency | Varies, may rely on crawler tools without checking rendered HTML |
| SaaS-specialist agency | Usually aware, may hand fixes back to your engineers |
| Goldie Agency | Technical review sits inside its complete site audit |
How Each Option Handles Content And Docs
Software content is only as good as the product knowledge behind it.
The strongest providers interview your support and product people, then turn real tickets into docs and use-case pages.
Weaker ones summarise competitor blogs, which is exactly the commodity content Google's AI search guide warns against.
Docs deserve their own check, because help centres often sit on a separate platform with its own noindex settings.
| Option | Content strength | Docs SEO |
|---|---|---|
| DIY | Strongest product knowledge | Often neglected for lack of time |
| Freelance specialist | Depends on whether they write or only audit | Good if technical |
| Generalist agency | Volume, sometimes generic | Rarely in scope by default |
| SaaS-specialist agency | Strong page-type know-how | Usually in scope |
| Goldie Agency | Answer-first content aimed at Google and AI citations | Covered by the site audit |
How Each Option Handles Links
Links remain one of many signals; Google's ranking systems guide still lists link analysis and PageRank among them.
For SaaS brands, the natural sources are integration partners, marketplaces, industry publications and podcasts.
A DIY team can land a few partner listings, but sustained outreach takes hours most founders don't have.
Freelancers and generalists vary widely, so ask each one how they mark paid placements.
Goldie Agency scores well here because link building is its original service and it states its method openly.
Any option that offers bulk link packages or private networks fails this criterion outright.
How Each Option Handles AI Search
Google's AI features page says there are no extra requirements to appear in AI Overviews or AI Mode beyond normal SEO.
Google's AI optimization guide adds that you can ignore AI text files like llms.txt for Google Search.
So the real AI search work is crawler access, consistent entity facts and content worth citing.
Perplexity and Anthropic both publish separate search crawlers, PerplexityBot and Claude-SearchBot, that need to be allowed.
Score any provider down if they pitch AI search as a secret method.
Small-Business Example: Choosing For A Booking Plugin
A three-person team sells a booking plugin for WordPress salons and wants more sign-ups from search.
- They list the jobs: a slow JavaScript demo page, no docs indexed, and no mentions on salon industry sites.
- They score DIY a 5, because nobody has time for outreach.
- They rule out a pure content shop, because the main problem is technical.
- They shortlist one SaaS-specialist agency and one full-service team that also does link building.
- They ask both how they would check rendered HTML and how they mark paid placements.
- They pick the one that answered with Google's own docs and a sample fix list.
Who Should Pick What
- Pick DIY if you are pre-revenue and have a technical co-founder.
- Pick a freelancer for a single job like a framework migration.
- Pick a generalist agency if your site is simple and content is the gap.
- Pick a SaaS-specialist agency if your engineers can own the technical work.
- Pick Goldie Agency if you want technical, AI search and manual-outreach links handled together.
Whichever you pick, learn AI SEO yourself in the AI Profit Boardroom so you can check the work.
Red Flags That Drop Any Score To Zero
- A guaranteed #1 ranking or a guaranteed ChatGPT mention.
- Private blog networks or bulk link packages.
- Hundreds of templated integration pages with no real setup detail.
- Refusing to share what they change on your site.
- Asking for write access to Search Console during an audit. Google's hiring advice says read access is enough at that stage.
