"We have been working with Ewan and the ROI team for a number of months now. Can't rate them and the benefits highly enough. The lead volumes have been fantastic."
"We worked out a plan for the website and a budget and the results were amazing. I again reached out to to get a Google Ads campaign. I had to reach out to pause the ads because we can't take on anymore work. Absolutely thrilled with the results "
"After trying all different types of advertising and other ways of getting more work which all failed, went to ROI. In the first week I got a renovation worth over 6k, a second few months later. My investment paid off and I have consistent work and happy to say my business has been saved."
"Absolutely stoked with the result that Ewan and the team at ROI are getting our business. If you want an experienced, trustworthy team in your corner - these guys are your go-to!"
"Fantastic company to work with. You can tell that there is a wealth of knowledge and experience at this company. They helped me increase the volume and quality of the leads I receive, along with improving my website so potential customers could use it more effectively. Highly recommended."

ChatGPT vs Perplexity for business visibility in 2026?
ChatGPT’s custom GPTs, now available as of December 2025, allow Australian businesses to create tailored versions of ChatGPT for specific tasks without needing coding experience. These customisations function as dedicated AI assistants trained on your provided data and instructions, accessible through the ChatGPT interface. Currently, creating a custom GPT involves using the ‘Create a GPT’ option within ChatGPT Plus. You define its personality, instructions, and knowledge base by uploading files (up to 20MB per file – supporting PDF, TXT, CSV) or linking to external websites. In 2026, OpenAI plans to increase the file upload limit to 100MB and introduce support for more file types, including DOCX and XLSX. The ‘GPT Store’, launched in late 2025, allows creators to share and potentially monetise their GPTs, though Australian GST implications for revenue are still being clarified by the ATO as of December 2025. These custom GPTs can automate tasks like drafting marketing copy, answering frequently asked customer questions based on your product information, or even analysing sales data. The functionality is accessible to Australian users with a ChatGPT Plus subscription, currently priced at AUD $30 per month. Understanding the limitations of the training data and regularly reviewing the GPT’s outputs remains crucial for ensuring accuracy and relevance.

ChatGPT’s custom GPTs, now available as of December 2025, allow Australian businesses to create tailored versions of ChatGPT for specific tasks without needing coding experience. These customisations function as dedicated AI assistants trained on your data and instructions, accessible through the ChatGPT interface. Currently, creating a custom GPT involves using the ‘Create a GPT’ option within ChatGPT Plus. You define its personality, instructions, and knowledge base by uploading files (up to 20MB per file – supporting PDF, TXT, CSV) or providing specific knowledge directly within the GPT builder. In 2026, OpenAI plans to increase the file upload limit to 100MB and introduce team collaboration features for GPT development, allowing multiple users within an organisation to contribute. Australian businesses can utilise this to train a GPT on product manuals, internal policies, or customer service scripts. Access to custom GPTs requires a ChatGPT Plus subscription, which is priced at AUD $30 per month in Australia as of December 2025. While the core ChatGPT model is hosted in US data centres, OpenAI assures data privacy compliance with international standards, including those relevant to Australian businesses. Effectively, custom GPTs offer a low-code way to build bespoke AI tools for internal processes or customer-facing applications.
When will ChatGPT ads launch in Australia?

These customisations function as dedicated AI assistants trained on your data and instructions, accessible through the ChatGPT interface. Currently, creating a custom GPT involves using the ‘Create a GPT’ option within ChatGPT Plus. You define its personality, instructions, and knowledge base by uploading files (up to 20MB per file – supporting PDF, TXT, CSV formats) or providing specific knowledge directly within the GPT builder. In 2026, OpenAI plans to increase the file upload limit to 100MB and introduce support for more file types, including DOCX and XLSX. Australian businesses can use this to train a GPT on product catalogues, internal documentation, or brand guidelines. Access to the GPT builder is included with a ChatGPT Plus subscription, which costs AU$30 per month as of December 2025. Custom GPTs can then be used internally by teams or, with appropriate privacy considerations, offered to customers as a specialised support tool. The key benefit is increased efficiency and consistency in responses, as the GPT operates within the defined parameters and knowledge base, offering a focused AI experience.
How to use ChatGPT for keyword research in 2026?

Currently, creating a custom GPT involves using the ‘Create a GPT’ option within ChatGPT Plus.

In 2026, OpenAI plans to increase the file upload limit to 100MB and introduce a team collaboration feature, allowing multiple users within an organisation to contribute to a single GPT. The GPT store, launched in late 2025, also allows businesses to monetise their custom GPTs if they choose, though Australian GST implications need consideration. These custom GPTs can automate tasks like customer support responses, content drafting based on brand guidelines, or internal knowledge base searches. While the base ChatGPT model is hosted in US data centres, data privacy considerations for Australian businesses are addressed through OpenAI’s data usage policies and the ability to control the data used to train your custom GPT.
What is AI marketing?
Google’s Performance Max (PMax) campaigns currently utilise a fully automated bidding strategy, leveraging AI to optimise bids across all of Google’s advertising channels – Search, Display, YouTube, Discover, Gmail, and Maps – to maximise conversion value for Australian businesses. Unlike manual bidding strategies, PMax doesn’t allow for individual bid adjustments. Instead, you provide Google Ads with a target return on ad spend (tROAS) or a conversion value. The AI then predicts which combinations of audiences, creatives, and channels will deliver the highest return, automatically adjusting bids in real-time. As of December 2025, PMax now includes enhanced audience signals, allowing businesses to provide more detailed customer lists and audience segments to guide the AI. Recent updates in late 2025 also allow for more granular reporting on channel performance, although detailed channel-level control remains limited. In 2026, Google plans to introduce more transparency around PMax bidding, with a focus on explaining the AI’s decision-making process. While PMax simplifies campaign management, understanding its automated nature and providing high-quality assets remains crucial for achieving optimal results in the Australian market.
What is social media marketing in Australia 2026?
TikTok’s ‘For You’ page (FYP) algorithm currently delivers content to users based on a complex system of signals, aiming to predict individual preferences and maximise engagement in Australia. The algorithm doesn’t rely solely on follower count. Instead, it prioritises several key factors: user interactions (likes, comments, shares, completion rate of videos), video information (captions, sounds, hashtags – including trending Australian hashtags), and device and account settings (language preference, country setting, device type). As of December 2025, TikTok is increasingly weighting ‘dwell time’ – how long a user spends watching a video – as a crucial signal. TikTok Ads Manager now includes detailed analytics on average watch time per ad, allowing businesses to optimise content accordingly. In 2026, TikTok plans to further integrate AI-powered content recommendations, potentially allowing for even more personalised FYPs. TikTok is also rolling out enhanced safety features in Australia, which may subtly influence content visibility. Understanding these signals, and creating content that encourages longer watch times, is key to organic reach on the platform.
