Naturaily Reviews & Testimonials

Web Development Review from Beata Twardowska
The team was committed, helpful, easy to collaborate, and most importantly professional and skilled. They knew perfectly well what solution we needed based on the goals we described to them. What we value the most is good communication. We were kept informed about the progress of work and we got answers to all of our questions.Our clients love the new design and now they have even better understanding of our services. We have also received many positive opinions from industry specialists.We are very satisfied with the cooperation and its results. There is not much to improve. When we first launched, we found the animations a little too fast and we had to adjust them.Every challenge has been met. Our new website is safe (0 attacks after launch), fast – despite using so many animations (page speed insight analysis showed 86 on the desktop and almost 60 on mobile), and both user- and seo-friendly.
Web Development Review from Ollie Maitland
We were particularly impressed by Naturaily's proactive and collaborative approach. They went beyond simply executing our requirements by taking the initiative to understand our underlying business objectives and offering valuable insights and recommendations. Their deep technical expertise in headless architecture, coupled with their commitment to delivering a high-quality solution and their strong communication skills, made them a truly unique and valuable partner.Our marketing team now has the independence to test and refine content thanks to Naturaily. The CMS overhaul and testing framework have made it easy to optimise our user experience without needing developer support. We can now collaborate more effectively than before, which increases productivity. We have also observed improved website performance, indicated by faster page load times. The successful deployment of a modern technology stack also provides a scalable foundation for future growth.They delivered on every performance goal while keeping us informed and building a platform that puts testing and innovation first. Naturaily's project management was highly effective. They consistently delivered items on time and were very responsive to our needs and feedback throughout the project lifecycle, demonstrating a strong commitment to our success.They guided us through every step of our platform migration with exceptional care and expertise. We're really happy with how everything has gone, and our collaboration with Naturaily is actually ongoing.
Web Development Review from Polina Medvedieva
High skills and responsibility make Naturaily a reliable, trustworthy, and professional technological partner. They grasp even the most nuanced details of our requirements and are effective in managing project needs.We can count on them even with the tiniest issues as the developers we work with are attentive, good communicators, and always stay in touch. They’re versatile enough to comfortably connect and engage with both technical and non-technical staff.Naturaily consistently delivers tasks and project stages on time, and we’ve seen a noticeable reduction in website bugs as a result. The great thing is that their team brings valuable proactive insights, thoughts, and suggestions to the table.Naturaily helped us drive the website project forward with a clear understanding of our strategic goals and operational needs – all while in a specific technological environment. They’ve been highly operational and creative whatever a challenge or change came.Naturaily used Jamstack architecture (Vue.js and Nuxt.js) to improve our website’s front-end interactivity and back-end efficiency. This upgrade laid the groundwork for additional features, crucial for the site's evolution and business growth. From the very beginning, they’ve supported us with great dedication and skillfulness, all while minimizing the need for continuous technical oversight.

We recently worked closely with Andrew and his talented team at Psychoactive Studios to redesign our website and refine our brand presence online for Hype Entertainment.From discovery session to completion the whole process has been fun and exciting - engaging with the passionate team and always having a big grin seeing the new stages of development as they are completed. The diverse team of talent was able to bring our futuristic vision to life, with 3D elements that exceeded expectations and silky smooth scrolling that takes you on a journey through space to see our creative installations.Highly recommend if you’re looking to take your branding to the next level!
NZ MindFuel's Review Sourced from Google
Have been meaning to write a positive review for Psychoactive Studios for weeks, but the Ecsplore brand that they helped us launch has been such a success we have not had a chance. Psychoactive understood our market well and were able to create branding the has connected extremely well with our customers. Whats more we were able to continue working smoothly through lock-downs and crazy events of 2022 via video meetings and email. If you need high end branding for a product Psychoactive is as good as it gets.
AVID Gallery's Review Sourced from Google
A great team of people who were a delight to deal with from our very first meeting through to the successful launch of our new website. We had some very clear and quite challenging objectives in mind and Psychoactive delivered exactly what we were looking for. We thoroughly enjoyed the team’s collaborative approach to problem-solving and the smooth and efficient way they dealt with any concerns or queries we may have had. Feedback on the new website has been overwhelmingly positive and we look forward to working further with Psychoactive as it develops in the future.

Bonfire Red Reviews & Testimonials
Darci Williams's Review Sourced from Google
I’ve always known Bonfire to deliver incredible work, but after getting to partner with them on my own brand, I can confidently say my (very high) expectations weren’t just met - they were far exceeded.They helped me clarify and crystallize what has always felt unique about Wayfinding, putting just the right words to our mission, vision, and values. It honestly felt like magic.Nearly every week, they would show me something new that brought tears to my eyes. The copywriting. The design. The way they listened deeply and carried my feedback into every interaction. Every aspect of the project felt best in class.And through it all, I genuinely felt like they cared about my brand as much as I did.I’m crazy about the final deliverables, but the impact of this work goes far beyond what they created. Since working with Bonfire, I feel myself standing taller, speaking more confidently about Wayfinding, and ultimately delivering an even better, more impactful experience for my clients.That gift is hard to measure.The quality of the work, the sheer amount they delivered, and the care they brought to every part of the process made this worth every penny I invested - and then some.If you’re looking for a partner to elevate or extend the impact of your brand, look no further. I truly can’t imagine a better brand, design, or copywriting partner.
Kristin Cruz's Review Sourced from Google
Thank you, Bonfire Red, for such a smooth and enjoyable experience. Your meticulous care for the work and the client shines through.So much more than design and development, beyond basic branding, you take the time up front to help your clients sort out who they are at the core of their brand, which feeds a healthy exploration from which every organization would benefit. The results are both stunning and meaningful.One thing I especially appreciate about BFR is you never settle for second best. Thanks for brining that energy to the Wayfinding brand!

7 FAQs About Answer Engine Optimization Companies
How much do answer engine optimization services cost?
On average, answer engine optimization services cost between $1,000 and $3,500 per month for small businesses and startups, while mid-tier retainers range from $4,000 to $12,000 per month.
Unlike traditional SEO retainers, AEO pricing is determined based on how much technical implementation, content production, and authority building the agency performs.
Common factors affecting the pricing include:
- Website complexity: Large websites require more data, entity optimization, and content restructuring.
- Content production: Creating AI-friendly guides, FAQs, comparison pages, and expert resources often represent the largest portion of an AEO agency’s output.
- Technical fixes: Schema markup, internal linking improvements, crawl optimization, and index management encompass frequent adjustments.
- Authority building: Digital PR, expert citations, and high-quality mentions are frequently priced separately.
- Tracking and reporting: Some answer engine optimization companies include AI visibility tracking, while others charge extra for monitoring across ChatGPT, Google AI Overviews, Perplexity, and Claude.
What do answer engine optimization companies charge that most buyers don't expect?
Many answer engine optimization companies charge their technical and editorial work separately from the retainer.
Other common exclusions include:
- Content production: Original expert articles, comparison pages, FAQs, and buying guides.
- Development work: Schema implementation, page template updates, and technical fixes.
- External outreach: Digital PR initiatives and link-building campaigns.
- AI visibility monitoring: Platform-specific reporting and citation tracking.
- Subject matter expert interviews: Original expertise used to strengthen authority signals.
How do I know if my current answer engine optimization strategy is underperforming?
Your AEO strategy is underperforming if AI engines like ChatGPT, Perplexity, or Google's AI Overviews rarely cite your brand when answering questions in your niche.
Here's how to diagnose it quickly:
- Zero or rare citations
Run 15-20 queries your customers would normally ask, across multiple AI platforms. If you're absent more often than not, that's your baseline problem. - Outdated or wrong information surfaces
When AI does mention you, check if it's pulling stale data, old pricing, or discontinued services. - Competitors dominate the answer box
If rivals consistently appear in synthesized answers and you don't, their content structure is simply more "extractable" than yours. - No structured data footprint
Missing schema markup (FAQ, HowTo, Organization) makes it harder for language models to parse and trust your content as a source. - Your content reads like marketing, not reference material
AI engines favor clear, factual, well-organized answers over persuasive copy.
The quickest fix would be to audit your query coverage, as traditional SEO metrics won't reveal this gap. You will need to query the engines yourself and track citation frequency over time.
Should I hire a specialist answer engine optimization company or a general SEO agency?
You should hire a specialist answer engine optimization company if AI visibility is now central to your customer acquisition.
While many traditional SEO agencies are expanding their offering into AEO services, specialized AEO providers understand how to structure answers for extraction (clear definitions, direct claims, logical hierarchy).
That said, a hybrid approach often works best. If your traditional SEO is already solid, a specialist AEO partner can layer in the missing technical and structural pieces.
If your SEO foundation is weak, fix that first. AEO without strong content fundamentals is like building on sand.
What is a realistic timeline to see results from answer engine optimization services?
Most businesses see first AEO results within 2-6 weeks, though this timeline might vary depending on where you're starting from and how solid your LLM brand visibility is.
Here's a breakdown by starting point:
| Starting Position | First Citation |
| Strong SEO foundation | 2-4 weeks |
| Moderate SEO presence | 4-8 weeks |
| New or weak domain | 8-12 weeks |
| Local service business | 3-6 weeks |
A few factors worth noting:
- Platform speed varies: Perplexity indexes new content within hours to days, while ChatGPT lags since it depends on training data plus limited browsing.
- Existing authority compounds: Roughly 76% of sources cited in Google AI Overviews already rank in the top 10 organic results, so traditional SEO strength directly accelerates AEO.
- Updates matter more than rewrites: High-value pages should be refreshed monthly with new statistics and examples, rather than redone completely.
Which AI search platforms should an AEO strategy target first?
You should prioritize the AEO strategy based on where your customers search, rather than on platform popularity alone. That said, ChatGPT and Google's AI Overviews are the safest starting point for most strategies, since they currently command the largest share of AI-driven search traffic.
Here are a few observations about each AI platform to consider:
- ChatGPT. With hundreds of millions of weekly users, it's become a primary research and purchasing-decision tool, especially for B2B and informational queries.
- Google AI Overviews. Since it's embedded directly in traditional search results, even users not actively seeking AI answers encounter it by default, making it nearly impossible to ignore.
- Perplexity. Smaller user base, but disproportionately influential among researchers, analysts, and early adopters who value citation transparency.
- Microsoft Copilot. Worth monitoring if your audience skews enterprise, since it's integrated into Microsoft 365 workflows many businesses already use daily.
Will answer engine optimization replace SEO, or do I need both?
No, answer engine optimization won’t replace SEO, as it builds on SEO’s foundations.
Most AI systems still discover and evaluate websites using the same signals that support traditional search visibility, including crawlability, content quality, authority, and structured information. AEO extends those fundamentals by making content easier for AI systems to interpret, summarize, and cite.
For most organizations, the progression looks like this:
- Build a technically healthy website.
- Establish topical authority through SEO.
- Improve content structure for AI retrieval.
- Monitor AI visibility alongside traditional rankings.
Companies that skip foundational SEO often struggle because AI systems have less trustworthy content to reference.
