Get in front of users who are already

searching for the products you sell

93% of global traffic comes from Google Search

When your customers are ready to make a purchase, they turn to Google and search for a business like yours.
But 75% of people don’t even click past the first page, so if your business isn’t in a top spot then you’re invisible to your customers. But your competitors aren’t.
SEO helps your business rank higher, putting you back on top and driving traffic and leads to your website with a high purchase intention.

Shoot to the top of Google with paid ads

Alongside an SEO strategy, paid ads bring a rapid and immediate traffic increase, boosting your position for the top spot and generating clicks. Offering an incredible ROI, our unique approach to organic and paid traffic is the number one strategy to increase sales.

In fact, a huge 75% is the average conversion rate for Google Ads. Combined with our holistic approach to digital marketing, including SEO and paid traffic, you’ll be picking up new customers by every means necessary.

I have been working with Select Simon Markus SEO agency for 2 months now. We had a new website and our business had been doing very well without a proper website until now, but we realized how many inquiries we were missing out on. I knew enough about what was required, but hadn't realized how big a challenge it was to get SEO right. Josh and the team spent time explaining and demonstrating the importance of SEO content, link building, internal links and page structure. As a result, in 2 months, our website went from ranking for 10 keywords on page 7/8+ to ranking for over 100 keywords on the first few pages of Google, with about half on page 1 and a handful already in the number 1 results. It's still early days and it's important to remember that SEO takes time and is exponential; once you start getting traffic from the right clients, your relevance grows quickly. But you can't skip the hard work and cost of getting it right from the start. I highly recommend Select Simon Markus, they take SEO seriously and get the job done. If you are looking to do it for cheap, you will waste your money and only get half the result, and cheap tactics will now punish your site.

Very impressed with Joshua's knowledge, and his generosity given the amount information he offered on our courtesy call. He was very honest and told me clearly what I should and should not spend my money on. Sounds like a great company.

I spoke with Theo at Select Simon Markusabout running my SEO campaign for my website. He was very knowledgeable and gave me a lot of guidance on the things I need to implement first. He wasn't pushy or trying to get me to sign up instantly and I would definitely contact him once my site was ready to get started with this. I have no doubt that they will be able to help me achieve my goals.

Select Simon Markus helped us rank for terms that were super relevant to us from a sales perspective including search terms like virtual tour company which is key for us to be seen for and helps boost online sales and enquiries. After working with other SEO agencies in the past who have not really been able to move the needle for us, Select Simon Markus really made it happen. We couldn't ask for more from an SEO agency. Thank You Select Simon Markus 🎯

Our Company’s Proven Process

How Do We Deliver Our SEO Services?


The key starting point to any successful PPC & SEO campaign is planning and preparation. The more we know about your business, the better work we’ll be able to perform.

On our discovery call we will:

  • Learn about your business.
  • Listen to you to understand exactly what you want to
    achieve from the campaign.
  • Understand what keywords you want to be seen
    for on Google.
  • Analyse the websites of your competitors whilst sharing
    our screen with you to show you exactly what
    they have done to get to where they are now.
  • Determine how long it will take to achieve your
    desired results and the investment required
    to get you there.

To understand the current paid ads and SEO situation in your industry, our in-house keyword research team performs an in-depth research and analysis process for your specific campaign.

We look for the “low hanging fruit” keyword ideas that other competitors may have missed, and we’ll also analyse the top ranking websites to see what keywords they’re actively targeting. We’ll deeply analyse Google’s ad stats and take a look at what the data is telling us.

Then, we’ll select the keywords we suggest you target, based on our expertise and your business objectives.


Once we’ve finalised the best keywords to target for your organic and paid campaigns, we’ll jump on a video proposal call to go over our findings. Here, we’ll tell you exactly how we’re going to get your business onto the first page of Google.

During this call we will:

  • Review our approach to a successful SEO campaign.
  • Discuss our paid ad strategy and how we suggest you optimise your ad budget.
  • Present our keyword research findings to you, outlining the best approach for a strategy moving forward.
  • Outline how our monthly and quarterly reporting process works, plus a live demo of our dashboard tool so you can monitor your campaign 24/7.
  • Break down our suggestions for your budget, and the results we can generate.
  • Run over our full terms of service.

Ready to go?

Look out for your Welcome Email from our Founder, Joshua George. This email will contain:

  • A link to schedule a time and date to jump onto the official onboarding call to go over the strategy for the next quarter.
  • A link to complete the direct debit mandate to allow for a seamless billing process.

The email will also contain the onboarding form to be completed prior to us starting the campaign. This form includes:

  • The best email addresses for us to send our monthly reports to.
  • Your website login details for us to make changes to your site.

Get ready for a call with all of the team as we’re going to run through the custom paid traffic and SEO strategy for your business.

This call is important as it:

  • Gives you complete clarity on what will be happening before the start of each campaign.
  • Ensures we are all in agreement that our holistic strategy compliments your goals.
  • Allows you to oversee each campaign comfortably and understand exactly what we’re doing behind the scenes to get you results.
  • Gives us another chance to show you how our 24/7 dashboard works, so you can monitor the progress of the campaign at any given time.

Everything confirmed and finalised, our team instantly get to work and help generate more revenue for your business.

We’ll send you updates every week on how things are going to ensure you’re never left in the dark.
