Tell us a bit about your business

They took the time to ask the right questions engaging in a comprehensive discovery process to work out the principal motivators of our firm’s development. Specifically, they diligently discerned our organisational identity, our core values and delineated the messages we intended to convey to prospective clients. The marketing playbook they drafted for us was thorough and encompassed an extensive analysis of our market providing strategic options of how we can better communicate our core values. This invaluable assistance through our rebrand strategy cannot be understated. They are continuing to help us discover what options are available to better communicate who we are to potential clients and show them how we can effectively serve them in our calling to deliver Just Redemptive Outcomes.

Tim Whincop, Director - Vocare

They’re flexible, they listen, and they communicate exceptionally well. I can pick up the phone or send an email and I get a response immediately. I also appreciate the fact that the people I spoke to during the onboarding process and the decision-making process are the people we work with. With other marketing companies you often speak to the salespeople and then once the sale is done, you never speak to them again. You don’t know anything about the people doing the work and you don’t have a relationship with them. With TheOnlineCo, the people that were involved in the onboarding, are the people that we are now dealing with as we work to build our business. This is quite unique. Buying anything is an emotional decision and I’m a little bit old school, but people buy from people they like. And I really like the team at TheOnlineCo

TheOnlineCo.’s ‘Digital Marketing Playbook’ process is powerful. As a Director of Zedu Ultrasound Training, I’ve experienced firsthand the impact of their strategic approach. From meticulous market analysis and targeted audience identification to engaging content creation and data-driven optimisation, each step has been a game-changer.

The Playbook has not only boosted our online visibility but also significantly increased our engagement and conversions. The personalised guidance and clear roadmap provided by TheOnlineCo.’s team of professionals have proven invaluable in maximising our digital presence.

If you’re seeking a comprehensive and results-driven digital marketing solution, guided by a team that will grow to become friends, look no further than TheOnlineCo.

Michael Duncan, Director - Zedu Ultrasound Training

Working with TheOnlineCo. team has been one of the most encouraging and specialised services I have experienced. The process of providing a digital playbook for our company was outstanding and I would highly recommend that anyone seeking to build their digital platform scope take the time to invest in the Digital Marketing Playbook process with James and his team.

From initial discovery conversations to massaging the final details, the experience was seamless and solely focussed on providing a unique and targeted approach to our individual needs as a client. We were absolutely blown away with the level of detail, accuracy, heart and investment into understanding our business’s goals, needs and areas of development and growth and providing it to us in a professional playbook presented in a simple and yet professional feedback session.

If you are considering TheOnlineCo. for your future endeavours I cannot stress enough, you will not regret it!

Kayleigh Alexandre, Creative Content & Branding Manager - HC

If you are thinking about doing the Digital Marketing Playbook with James and TheOnlineCo. team – do it! You won’t be disappointed. 

The playbook process started with an initial exploration meeting and it was clear to me during that meeting that this was an hour of time well invested! James and his team had clearly done their research prior to our meeting as they came prepared with questions specific to our business and industry. 

The playbook was then presented by the team in our next meeting and I have to say I thought it was fantastic. This document is over 70 pages long and covers everything from my competitors, to our brand voice and values, a really in-depth story of our target markets (this is the part I really liked) and then the strategy and tactics to execute.

It is quite an amazing document and one that I highly recommend you do if you need to get your digital marketing strategy and execution sorted. 

Michelle Blicavs, Australian Consulting Surveyors

The Digital Marketing Playbook process was quite simply exactly what my business needed. Not only did it take a deep dive into who my ideal clients are and their needs and wants but it also outlined very clearly what marketing activities needed to be done and when to achieve my business goals. On top of that, TheOnlineCo. team looked at my website and branding and assisted with making the necessary changes in these areas as well.

If you have been considering working with a digital marketing agency you need to speak with James and TheOnlineCo. team, they invest in their clients’ businesses and it shows in the work they do and the results they achieve.

Micheal Anderson, Aurora Wealth

TheOnlineCo. team were very professional and thoroughly committed to understanding our business from the start of our marketing journey. They took the time and created a very detailed and informative analysis of our competitors, helped us to understand our avatar and our customer story.

From there they provided us with very detailed strategies and recommendations for us to meet our business goals. The overall process was a great experience and they delivered on everything we had expected and more, this gave us the confidence to move forward with our marketing plans.

MORE THAN A BROCHURE

A good website isn’t a brochure. It’s the hardest-working member of your sales team.

Plenty of Sydney website design agencies can make a site look good. Fewer can make it load fast, rank well and actually convert. As a website development agency that works across SEO, ads and design under one roof, TheOnlineCo. builds every site to do all three – whether you need a brand-new build or a redesign of something that’s stopped pulling its weight.

SOUND FAMILIAR?

The problems we hear most from Sydney businesses

An outdated site that undersells you

Your business has moved on, but your website hasn’t. We rebuild sites so they reflect the business you are today, not five years ago.

Poor mobile experience

Slow, clunky or hard-to-navigate on a phone means lost enquiries. Every site we build is designed mobile-first from day one.

Slow load times

Every extra second of load time costs you visitors and rankings. We build lean, optimised sites rather than bloated page-builder templates.

A CMS you can't actually use

If updating a page means calling your developer, the site is working against you. We hand over a CMS your team can genuinely manage.

Not built with SEO in mind

A beautiful site that can’t be found is a beautiful waste of budget. Our development and SEO teams work from the same brief, from day one.

No way to measure ROI

If you can’t tell what your website is doing for the business, it’s hard to justify investing further. We build in the tracking and reporting to prove it.
