Reviews highlight their collaborative approach and proficiency in SEO and PPC campaigns, with 70% of clients noting improvements in website ranking and digital visibility. While 180Fusion excels in project management and client service, some feedback suggests variability in SEO effectiveness.
Reviews mention Trustworthy
Clients consistently express a strong sentiment of trust towards 180Fusion, emphasizing their transparent communication and ethical practices. One client noted, '180Fusion is more trustworthy than past agencies because they let us know of any expenses or activity upfront.' Another remarked on the attentive account management, stating, 'They've constantly looked at what work elements their customers need to know and give consent on.' Overall, the feedback indicates a high level of confidence in 180Fusion's integrity and capabilities.-
SEM for Auction House
5.0 Feb 2, 2016This is why clients need to find companies that they trust. They're investing more than $2,000 into SEO, without really understanding the efforts that are being made, beyond being told that there are links being put out, ranking has improved for certain categories, and so on. There is nothing concrete, but this is an industry-wide problem. I think the people at 180Fusion are very smart and I trust them, but my concern is related to how the industry as a whole can be improved.

SEM for Livestock Farm
5.0 Feb 5, 2016Overall, 180Fusion has strong business ethics. They've constantly looked at what work elements their customers need to know and give consent on, contrasting with other companies that would take over and bill their customers without any responsibility for results. 180Fusion is more trustworthy than past agencies because they let us know of any expenses or activity upfront. We have a contract, and we get reports. They talk me through any questions I may have, and ask for permission before moving ahead with any work.

Search Engine Marketing for Agricultural Product Seller
4.5 Nov 22, 2016In addition, the previous company we were using for PPC and SEO had gotten us a Google penalty. 180Fusion was able to get that penalty relieved within 3 to 4 months. Clients can trust 180Fusion's account reps and keep an open line of communication. Their people know what they're doing.

Why Trust Clutch
At Clutch, we believe trust is the foundation of every business relationship. Our mission is to help buyers make confident, data-backed decisions informed by real client experiences.
Every review on Clutch undergoes a rigorous, human-led verification process to make sure it’s valid. Our team of specialists confirms the identity of each reviewer, ensures the project is legitimate, and only publishes reviews that meet our strict criteria.
Verification doesn’t stop at the point of publication. Our Trust & Safety team routinely audits older reviews against our guidelines. When reviews fall short of our standards, we remove them.
We evaluate service providers using a structured methodology that combines:
- In-depth client interviews and ratings
- Comprehensive project details
- Market presence
- Portfolio examples and industry recognition
This data powers tools like the Leaders Matrix, which helps you compare agencies directly. Our research team curates rankings by weighing verified reviews most heavily, so the most trusted and experienced providers rise to the top.
Using this unique combination of verified client feedback and provider-supplied insights, Clutch distills the most important details into clear, digestible summaries so you have everything you need to make confident, informed decisions quickly.
We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.
Clutch’s commitment to transparency is ongoing. We’re constantly refining our systems to protect the integrity of reviews and support you in finding the right agency.

A Clutch Leaders Matrix provides a broad view of the top-performing companies in a particular service or location. Each company featured in a Leaders Matrix is evaluated based on Focus and Ability to Deliver. The size of each circle indicates that company’s size.
By using verified reviews, focused service details, and real project data, the Leaders Matrix highlights companies that consistently deliver and stand out from the rest. Each company’s position is based on how well they focus on a service area and how consistently they deliver results, helping you make informed, confident decisions. Learn More
