The 5 Best SEO Service Companies in South Africa

Luke Marthinusen | March 21 2020

The best SEO Services Companies in South Africa are:

  • Algorithm Agency
  • MO Agency
  • Ruby Digital
  • SEO Pros
  • Web SEO

Choosing an SEO services company is not an easy thing. The SEO landscape is always changing as the dominant search engine Google modifies their algorithm. And SEO services companies tend to rise and fall.

As someone who has been in the industry for over 10 years now, I've seen South Africa's top SEO companies compete for the coveted top spots on Google, and for the big budget clients. I've seen them come and go, get procured by above the line (traditional) agencies looking to go digital, and I've seen them disappear altogether.

The SEO providers in South Africa remain a combination of small (1-3 staff) and mid-sized (3-20) companies. There are very few large SEO firms in SA, the likes of which are very common in Europe and the US.

The difference between SEO and SEM

A distinction needs to be made between Search Engine Optimisation (SEO) and Search Engine Marketing (SEM).

SEO is the process of ranking on search engines without paying money to the search engine.

SEM is the process of ranking and being visible on search engines by paying money to search companies via products like Google Adwords. In the context of SEO companies, SEM loosely extends to display advertising on websites that are not search engines, and paid ads on social media platforms.

This article deals with SEO - the process of ranking without paying for clicks or impressions.

I do think however that most of the SEO companies mentioned below gain a significant, if not majority of their company revenue as 15 - 25% fee on ad spend. Paid and organic search do work well together - when done the right way.

What make an SEO Company great?

The secret sauce of an SEO company and SEO in general is a combination of factors.

Visionaries and staff

The best SEO companies are headed up - strategically or owned - by one or two SEO Pros. This person has worked with SEO for 5 - 10 years and knows exactly what he/she is doing.

These individuals can read your SEO landscape like Naas Botha reads a rugby game. They can see where you are doing well, and where you need support and hard work. And like a rugby team preparing for a Rugby World Cup, can appreciate that showing up at the World Cup final requires years of consistent work.

These visionaries only have so many hours to work on your SEO every day. Yes, SEO Pros have families, pets, and pastimes outside of the work they do for you.

So, they rely on staff to deliver your SEO services. The staff needs to be well trained and versed in timeous delivery in order to deliver results. Have you ever been sold by the 'A-team', and handed over to the 'B-team' to deliver?

Unfortunately what makes a great SEO Pro, doesn't always translate to a good leader and a sound business delivery process.


Multidisciplinary Approach

SEO is no longer a purely technical pursuit, and there are multiple factors that contribute to On-page and Off-page SEO. A good SEO company needs to deliver on all of these factors. Or work well with teams that can. These include:

1. Content Marketing

  • Blog posts
  • Time on site
  • Social media content and shares
  • eBooks and whitepapers
  • Videos and audio recordings
  • Infographics or other visual content

2. On-Page SEO

  • Title tags
  • Meta descriptions
  • Internal links
  • Image alt tags
  • Content structure

3. Off-Page SEO

  • Backlinks
  • Social signals (likes & shares)
  • Trust

4. Black-hat vs White-hat SEO tactics

  • Black-hat methods: Optimising for search engines only. This involves exploiting weaknesses in search engines to get results and rank very quickly. By ignoring the human element and breaking or bending the rules SEO companies can rank a company quickly. However, Google is constantly waging war against sites using these methods. One sweeping Google algorithm change can wipe a site using Black-hat methods off Google entirely. Here is an article by a South African SEO company explaining what can be done after a Google penalty. I.e. The wrong move by an SEO company and poof goes your organic search traffic. 
  • White-hat methods: Optimising for humans involves focusing on the human audience that will be engaging with the website content. By consistently producing quality content that is easy to read, informative, and legitimately optimised, websites start to rank well over time. Time being the operative word here. White-hat SEO takes time. (and consistency...)

5. Complimentary digital agency services

  • Website design and development
  • Content marketing
  • Social Media marketing
  • UX design
  • Marketing automation



In my opinion great SEO that works long term is not R3000 a month. It's at least R10,000 per month and upwards. I'd be interested if you have had great SEO results with monthly costs less than this? Connect with me and let me know. I'd be happy to put your story in here.


How did I come up with this list?

Domain Authority

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). A Domain Authority score ranges from one to 100, with higher scores corresponding to a greater ability to rank.

Technical website check

Have you ever heard the comment, 'The mechanic's car is always broken.' ? So I'd rather have the mechanic whose car is running, to work on my car. It means their business is running well and they have time to work on their own car. The same goes for SEO companies.

I excluded a few SEO companies because they had tracking errors on their website. Seriously, if you are selling your customers SEO services that generate revenue, you should get your own house in order. Loads of website errors, missing or broken tracking codes, and old tracking code technologies the SEO companies I reviewed. These firms were excluded. See below for a well known S.A SEO company

Alexa Rank

Alexa rank is a measure of website popularity. It ranks millions of websites in order of popularity, with an Alexa Rank of 1 being the most popular. Alexa Rank reveals how a website is doing relative to all other sites, which makes it a great KPI for benchmarking and competitive analysis.

I would not bet the farm on Alexa rank, but it is one of the best freely available benchmarking tools available to us. Some of the SEO Services firms are nowhere to be found when it comes to Alexa rank. Go figure!

Rankings for core services

I looked at national and local listing rankings for keywords related to SEO Services. Their first page rankings, and the difficulties of the keywords they were ranking for. If you are going to sell rankings, best you are able to do it for yourself.

Word of mouth / awareness in the S.A marketplace

Lastly, I've been in the digital industry building websites, doing SEO, conducting conversion optimisation projects, and building digital ecosystems for over 10 years. I've shared clients with these SEO service companies. I've had clients praise and bemoan many of them.

Below are the firms I'd reach out to if I was looking for an SEO Company. Just make sure you get the 'A team.'
