10 Best B2B SaaS SEO Agencies in 2026 (& How to Evaluate Them)

In our experience working with dozens of B2B businesses over the last 10+ years and hearing about their experiences working with other SEO agencies, we’ve learned that most B2B SaaS SEO services focus on things like improving keyword rankings, fixing technical SEO issues, and increasing domain authority. These activities are helpful, but without a clear strategy for ranking for high buying-intent keywords, they don’t drive meaningful increases in MQLs, SQLs, or MRR.

At Grow and Convert, we believe the primary goal of SEO for B2B SaaS companies should be to generate more demo requests, trial signups, and pipeline—not just to grow organic traffic or website authority, or to have a cleaner site architecture.

We’ve demonstrated this is possible in numerous case studies:

• All-in-one SaaS Product Case Study – We share how we grew demo signups to 150+/month for a large SaaS platform that has numerous à la carte solutions inside of it.
• Geekbot Case Study – We share how we drove 1,700+ signups for the self-service SaaS company Geekbot by starting with bottom of the funnel keywords and working our way up the funnel to mid/top of the funnel keywords. We also show how conversion rates differ. 
• Circuit Case Study – This article shares how we moved a blog from a subdomain to subfolder while following our SEO content strategy and grew trial signups to 250+/month.

So, in this post, we’re going to share the key factors B2B SaaS companies should consider when evaluating SEO agencies, explain how we’ve addressed each at our own agency (including case studies showing the results we’ve achieved), and share a list of other SaaS SEO agencies whose names we hear come up often.

Key Factors to Consider When Evaluating B2B SaaS SEO Agencies

Below are the key factors we’ve found that separate effective B2B SaaS SEO agencies from those that don’t work out. These are based on directly seeing the work produced by agencies our clients have previously worked with, seeing what results those agencies achieved (or didn’t achieve), and hearing the frustrations our clients have voiced about those engagements.

• Factor 1: Do they prioritize ranking for high buying-intent keywords over technical SEO fixes?
• Factor 2: Do they actually create content, or just deliver keyword lists and briefs?
• Factor 3: Do they prioritize conversions over traffic?
• Factor 4: Do they have a process for writing product-focused content that converts?
• Factor 5: Do they have an actual AI search strategy?

Factor 1: Do they prioritize ranking for high buying-intent keywords over endless technical SEO audits or general-purpose linkbuilding? 

We’ve noticed that SaaS marketing agencies (as well as in-house SEO teams) often focus the majority of their SEO efforts on “on-site SEO” (e.g. technical SEO audits, sitemaps, site structure, internal linking, etc.) and general purpose link building (links built to the homepage or some key pages aimed at increasing overall domain authority), while giving a lot less focus, priority, and effort to what we feel is the most important part of SaaS SEO strategy: Identifying high buying-intent keywords and creating content or pages designed to rank for those keywords. 

We think this is backwards. 

In our view, technical SEO audits are something you do once at the start of an engagement and then revisit maybe once a year or when a major change happens to the site architecture, which is rare for most B2B SaaS companies. Internal linking should be part of your content strategy, not a standalone SEO activity, and link building should only be done as a means of ranking for your highest value keywords, not as an end in itself.

Because otherwise, what’s the point? If you (1) haven’t identified what your highest value keywords are and (2) don’t have pages on your site specifically created to fulfill the search intent of those keywords, then what are you possibly hoping to achieve with technical SEO or link building? 

What use is high domain authority (the goal of most efforts to acquire backlinks) if you don’t have pages on your site created specifically to rank for your highest value keywords? Do you know what your highest value keywords are?

These may sound like obvious mistakes that no one would make, but it’s shockingly common. We see this backwards approach to SEO all the time. A ton of effort is spent on technical SEO and “cleaning up the site,” while a lot less effort is spent on identifying highest value keywords and creating content aimed specifically at ranking for them. 

Inevitably, in these scenarios, SaaS companies become frustrated when all the budget and time spent on SEO fails to produce any measurable increase in qualified leads or product signups.

It’s also worth noting that most B2B SaaS companies that can afford to hire an SEO agency already have a decent website. Technical SEO fixes, if needed at all, shouldn’t take months to complete. At our agency, we handle any necessary technical cleanup in month one of an engagement so we can move on to what actually drives results—ranking for high-intent keywords.

Factor 2: Do they actually create content, or just deliver keyword lists and briefs?

When we have seen keyword lists from SEO consulting services or agencies, there are often several issues with them. 

First, they’re often just massive lists of hundreds of keywords that B2B SaaS companies could get for themselves from any SEO tool. Some agencies do the hard work of categorizing or prioritizing these keywords by buying intent, but from what we’ve seen, most do not. And these SEO tools (where most agencies are getting these lists) almost always suggest tons of low buying-intent, high search volume keywords. 

They don’t interview sales, product, or customer support to deeply understand pain points of the target audience and uncover non-obvious but high converting, high buying-intent keyword ideas. You need humans to do this hard work. 

Second, these lists aren’t actionable. The vast majority of companies don’t have the resources to produce over 200 articles that are high-quality and crafted well enough to actually have a shot at ranking. So while this kind of keyword research may make the SEO agency feel productive, it leaves the client overwhelmed and wondering how they can possibly rank for all of those keywords. 

Compounding this issue is that most of the time, the SEO agency that provided the list will only create “content briefs” for each keyword, but they won’t actually write and publish the pieces. (Or, if they do, they’ll charge an enormous amount to do so.) 

Unfortunately, content briefs don’t rank. Pages published on the site that match search intent rank. These take time and effort to produce. So, it’s no wonder many agencies don’t do this. Heck, many SaaS brands don’t even do this. If an agency isn’t producing the actual content, they’re leaving the hardest part of SEO to you.

Factor 3: Do they prioritize conversions over traffic?

Next, in addition to emailing their clients unreasonably large keyword lists produced by an SEO tool, most B2B SaaS SEO agencies prioritize keywords by chasing traffic over conversions.  

We’ve talked a lot about why this is a problem, but in short, these agencies tend to spend a lot of their efforts trying to rank for top of funnel keywords that have high search volume but low buying intent.

By our measures, these keywords have very low conversion rates — a point that is neatly summarized in this Google analytics screenshot from our article on Pain Point SEO (our agency’s foundational SEO content strategy): 

The right-most column shows new user signups for each of the URLs listed. The three boxed posts follow the Pain Point SEO approach and rank for keywords with high buying-intent. The rest rank for something the target audience could search for, but not a high buying-intent keyword. 

The new user signups from the three Pain Point SEO posts are hundreds of percent higher. 

We also showed this at a larger scale in an analysis of 60+ posts for our client Geekbot:

The posts targeting high buying-intent keywords (which we’ve traditionally referred to as “bottom of funnel”) didn’t just convert a bit better than the higher-volume-lower-intent posts, they converted 2400% better. 

Within that case study, you can read about how the higher conversion rates more than made up for any differences in search volume or traffic between the two buckets. 

This is why, in our experience, prioritizing keywords by intent — not search volume and traffic potential — is far more effective for driving conversions. But most B2B SaaS SEO agencies don’t use strategies that follow this logic.

Factor 4: Do they have a process for writing product-focused content that converts?

Next, in order to rank for high buying-intent keywords (e.g., “best accounting software,” “social media management software,”) and convert that traffic into leads, you need to be good at product copywriting. 

Pages ranking for high buying-intent keywords usually talk a lot about products. So, if you want to rank for these keywords, your pages need to talk about products in-depth, including, for example, an explanation of key features, the use cases for each feature, and what differentiates your product from others in your space. 

This requires a different writing skill set than traditional “blog writing.” First, most blog writing is self-researched, but product copywriting shouldn’t be. The traditional blog writing workflow involves handing a writer a keyword and asking them to come up with what to write on their own. Sometimes the writer is given a “content brief”, but even those are mostly dictating the subheaders based on what the existing ranked pages are already saying. 

That may be fine for introductory, top-of-funnel keywords like “accounting tips for startups,” where most of the articles ranking say the same thing, so a reasonably smart writer could digest the tips in a couple of hours and produce something similar but professional. But if you’re going after a buying-intent keyword like “accounting software for startups,” then you need to actually discuss the details of your software: 

• Outline your features and benefits
  • Why does your feature set look the way it does?
  • What are the most important benefits?
  • Are there any design details that are important? 
• Compare your software with others
  • What differentiates yours from others?
  • Where in the market do you sit? 
  • Are there certain use cases where a competitor might be better?

No freelance writer is going to be able to write this on their own. 

First, they’re going to need to interview product experts at your company to get this information. Most B2B SaaS SEO agencies don’t have these interviews as part of their content creation process. 

Second, they need to be able to write this kind of content well. How do you sell the features without being too salesy? How do you contrast with competitors without being too aggressive or trashing them? These are hard skills to learn. Some writers on our team have told me that our writing is more like landing page copywriting than blog content writing. They’re not wrong.

Factor 5: Do they have an actual AI search strategy?

With the rise of AI search tools like ChatGPT, Perplexity, and Google AI Overviews, many B2B SaaS companies are asking whether their SEO agency has a strategy for showing up in these platforms.

The problem is that most agencies don’t have a clear AI search strategy yet. Instead, most SEO agencies just test random tactics they see online, such as adding llms.txt files to the site, changing headings to questions, adding FAQs to every page, or commenting on Reddit threads. These tactics may or may not help, but they aren’t a real AI search strategy.

Our approach to AI search visibility at Grow and Convert is what we call Prioritized GEO, and the pyramid below shows how we recommend brands prioritize their efforts to improve their visibility in LLMs and AI engines:

The foundation of any AI search strategy is showing up in traditional SEO searches for topics where you want visibility. This is because LLMs search the web to formulate their responses, particularly when users ask for product recommendations. In our research, we have also found a 72% correlation between ranking on the first page of Google and being mentioned by AI tools like ChatGPT and Perplexity. When our clients ranked in the top three positions in traditional search, that correlation increased to 77%. We do this through the bottom two sections of our pyramid: Content on your site that tanks for relevant keywords (Tier 1) and getting mentions of your brand on other people’s content that also ranks for these keywords and topics (Tier 2). 

So when evaluating B2B SaaS SEO agencies, it’s worth asking whether they have a strategy for AI search visibility, and whether that strategy is grounded in creating content that ranks for bottom-of-funnel keywords.

Best B2B SaaS SEO Agencies

Below, we cover the best B2B SaaS SEO agencies to consider, starting with our own. For each, we’ll explain their approach to doing SEO, what they specialize in, and what types of companies they have worked with.

Since we outlined the key factors for evaluating B2B SaaS SEO agencies above, we’ll also share how we’ve addressed each of these factors at our agency, including case studies showing the results we’ve achieved.

1. Grow and Convert

Grow and Convert is our SEO and GEO-focused content marketing agency. We’ve spent over 10 years doing SEO and executing content marketing strategies that drive trial signups and demo requests for B2B SaaS companies, not just traffic.

Unlike agencies that optimize for top of the funnel metrics like traffic or rankings, we focus on bottom of the funnel content that generates qualified leads and measurable ROI through our Pain Point SEO and Prioritized GEO frameworks.

We have worked with B2B SaaS companies at various stages, from startups starting their first scalable content strategy to growth-stage companies looking to scale growth through content, SEO, and AI search.

Fundamentally, we feel our process is better aligned with B2B SaaS clients’ desired outcomes (rankings for high buying-intent search terms) and is more likely to actually achieve those outcomes because of what we prioritize. 

Below is each step of our process, listed in order of priority. 

Priority 1: Finding the Most Valuable Keywords to Target

Unlike traditional SEO firms that launch headfirst into technical SEO or link building without a keyword strategy in place, our focus starts with the keywords for which we want to rank. 

Ranking for target keywords that can drive meaningful results is literally the entire point of SEO. Nothing matters if you don’t know which keywords you’re targeting. Link building doesn’t matter. Technical SEO doesn’t matter. Yet, as we said above, we’ve had many clients who’ve spent months on all kinds of SEO activities without an agreed upon list of their most valuable keywords. Or, only slightly better, their target keyword list is only one or two keywords. 

Also, a crucial detail is that both the words “valuable” and “keywords” are equally important. Who cares about ranking for keywords loosely related to your product if they don’t bring you any business? Sure, your organic traffic will increase, and you can post that on Twitter and brag about it, but if the keywords aren’t ultimately leading to sales, then it doesn’t give clients what they want.

We’ve linked to these articles already, but to recap, you can read more about our high-value keyword strategy here and here. A case study quantifying the value of high buying-intent (bottom of funnel) keywords can be found here. 

To emphasize my point about priority, every other SEO activity we do (listed below) is in the service of ranking for these high-value keywords. This is our entire goal for clients. 

Priority 2: Creating Product-Focused Content Aimed to Rank for These Keywords

Second, and equally as important as the first priority, we produce individual pages to rank for each high-value keyword we are targeting. We don’t use the sprinkle method, meaning we don’t produce a single “small business accounting guide” that’s aimed at ranking for 10 different accounting keywords. 

We analyze the existing search engine results page (SERP) for each keyword, determine search intent, and produce a unique piece of B2B SaaS content that (a) has the necessary on-page optimization to rank and (b) better fulfills search intent than the existing results. 

And because most of our keywords are high buying-intent (“best accounting software,” for example), we sell the heck out of our client’s products and services in these articles. 

We get into the details of features, we explain the nuance of benefits, we weave in testimonials and case studies, and we differentiate our client’s products from those of their competitors (sometimes gently, sometimes aggressively). 

We base all of this on extensive interviews with product experts, product demos, and sometimes demo accounts (so we can use the product ourselves). We have been doing this for years and have an extensive writer training process that has helped us build a tight-knit team of product copywriters. 

This product-focused content is also the foundation of our AI search/Prioritized GEO strategy. LLMs search the web when users ask for product recommendations, and your content is how they understand what you offer, who you serve, and how you’re different from competitors. If your content doesn’t clearly communicate your product’s features, use cases, and differentiators, LLMs won’t know when or how to recommend you.

Priority 3: Site Cleanup and Technical SEO

You may be wondering, “How could this be third in the priority list? If the technical SEO isn’t in order, won’t you have trouble ranking for those high value keywords?!” Our answer is, “Yes, you would.” In fact, we start every client engagement with an SEO audit precisely to check for technical issues with the site that may hurt our ability to rank. Then, we either fix or suggest fixing the technical issues before we get started publishing.

So, like I said above, just because we list this as our third priority doesn’t mean it happens third chronologically. 

But, it’s third on our priority list by importance. Meaning, for us, site cleanup and technical SEO is only important insofar as it helps our content (Priority #2) rank for the most valuable keywords (Priority #1). Yes, if there are glaring technical issues, such as multiple H1s on a page, thousands of no-value, no traffic pages eating crawl budget, the entire site randomly no-indexed (you’d be surprised!), etc. — we’ll fix those problems immediately. 

But many times, there are no problems with the site! 

Contrary to what most SEO agencies will tell you, most B2B SaaS websites of decently sized companies that can afford to hire these agencies aren’t a hot mess. Take, for example, the marketing sites of most B2B SaaS companies: they’re not even that big. They usually have something like 10–20 largely static pages (product, solution, pricing, etc.). So why are these companies being sold months of SEO audits and technical SEO “cleanup” by SEO agencies? It makes no sense to us. 

We do technical SEO and site cleanup fixes; we’ve done a lot of it for our clients. We do a site audit, and we prioritize issues by importance and severity. But for us, it’s just something to get out of the way so that our content (#2) can rank for our high value target keywords (#1), not something to extend for as long as possible to keep charging the client.  

Priority #4: Link Building and Off-site Mentions

The final part of our SEO process is getting your brand mentioned on other sites. This includes both traditional link building and off-site mentions for AI search visibility.

For traditional SEO, link building works. But like technical SEO, it doesn’t pay the bills without high-quality content (#2) aimed at the right keywords (#1). It’s just a means to an end.

For AI search, off-site mentions matter because LLMs search the web to formulate their responses. Getting your brand mentioned on sites that rank for your target keywords can increase the likelihood that AI tools like ChatGPT and Perplexity recommend you. This is the second tier of our Prioritized GEO framework — it supports AI visibility, but only after you have the foundation of owned content that ranks.

In both cases, we’ve seen clients come to us after spending years paying untold sums on link building or PR without even having a clear set of high value keywords for which they’re trying to rank, much less the content they need to actually achieve those rankings. When we ask, “Why are you building links?”, they tell us, “Our SEO agency said it was important to get rankings.”

What rankings are these exactly? No one knows.
