15 B2B SEO Agencies in London for Quality Results in 2024

A successful business venture is no longer about simply developing a product and gearing sales towards a target market. SEO is now a major player in SaaS marketing.

Implemented well, SEO can help your SaaS take off by increasing online traffic and optimising your visibility online. If it’s not prioritised, your product will lose out. Whether you’re starting out or consolidating your B2B business, chances are your firm could benefit in multiple ways from working with an SEO agency. 

The typical buying group for a B2B solution involves around 10 decision makers, each one carrying out independent research to inform their own decision, most likely online. In fact, 89% of B2B buyers use the internet for research, 71% of which start with generic searches. This means that your website needs to be attractive, informative, and ideally appear on the first page of Google. Search marketing is an important part of B2B SEO strategy, but it’s not the be-all and end-all. Working with an SEO agency will create a holistic approach that identifies and uses all areas for potential.

At Skale, we pride ourselves on being different from the average B2B SEO agency. To start with, we don’t think rankings and traffic are the be-all and end-all. We prioritise driving business KPIs to increase SQLs; high rankings are just a good indicator of success. 

Our in-house SaaS experience also differentiates us from other agencies: we believe that experience is the best guarantee of success. 

To scale your SaaS SEO channel, you need to work with a SaaS SEO agency that has actually driven growth at SaaS companies. At Skale, we also think that an in-depth monthly report is much more valuable than a one-dimensional links spreadsheet. 

Transparency is key: we’ll work with you to build an SEO model that ticks all your boxes. 

As a remote company, you have the advantage of being able to work with us from anywhere in the world, benefiting from local SEO wherever you are.

How to choose the best B2B SEO agency for your SaaS

When it comes to assembling a digital marketing strategy, choosing the right B2B SEO agency is perhaps the most important step. 

First, consider your impression of their own website. Done well, it should showcase exactly what they’re able to do and put what they preach into practice. 

Second, check reviews and testimonials, and request work samples or case studies where necessary. You have to be meticulous when finding a B2B SEO agency — don’t rush it. Look out for red flags such as no clear SEO roadmap strategy for their own site, low-quality writing on emails/posts/social media, and unrealistic SEO goals in case studies. 

Look through their services and begin to identify the SEO tools that you would like to focus on for your company. Educate yourself about what’s on offer and have a starting point in mind so you can discuss potential strategies.

Prepare a list of questions to ask in order to determine the agency’s legitimacy. Don’t be afraid to ask in-depth questions, such as ‘How can I track the changes made on my website?’, or personal questions like ‘What is your client retention rate?’. You don’t want to waste your time on agencies that are all talk and no results.

It is also advisable to request a SaaS technical SEO audit. Discuss this with your prospective agency, but most high-quality B2B SEO companies should encourage an audit before partnering. 

The chosen agency must: 

1. Fully understand and cater to the specific mindset of B2B buyers. 
2. Be able to offer bespoke SEO strategies that fulfil your requirements, ideally based on a full SEO audit. 
3. Provide good value for money. 
4. Offer services that can adapt to new situations or requirements. 
5. Demonstrate good expertise and knowledge of the industry you’re in. 
6. Boast an engaging website of their own; they should be pulling out all the stops for their own company to showcase their SEO and web design skills.
