Content Marketing Review from Mckenzie Ycmat
I've worked with Siege since 2016, and there's a reason I've brought them with me to nearly every company I've joined since. I've partnered with a lot of agencies over the years, but Siege consistently stands out because they don't just execute SEO tactics, they become an extension of your team. They take the time to understand your business, collaborate across marketing, and build content strategies that actually drive measurable results. One of the things I appreciate most is how proactive they are. They bring ideas to the table, back recommendations with data, and genuinely care about long-term growth rather than chasing quick wins. The impact they've had on my career has been significant. At multiple companies, their work has helped us grow organic traffic, strengthen our content strategy, and prove the value of marketing initiatives. They're one of the few partners I've trusted enough to advocate for repeatedly, including making sure I could continue working with them after changing jobs. The fact that I've spent nearly a decade recommending Siege internally says everything. They're one of those rare agencies that consistently exceed expectations, and I'd recommend them without hesitation to any marketing team looking for a true strategic partner.

1 2's Review Sourced from Google
We hired flexsin technologies to build software for us in July 2022. They agreed to sign NDAs and all relevant paperwork. They prepared the NDA as they preferred it and sent it to us for review and signature. We reviewed the NDA and changed the Jurisdiction to UK and sent it back to them for a signature which they delayed in signing up to date. After they reviewed everything, they gave us an estimation of USD 17,000. They sent us a contract with upper price cap stating that any extra activities and costs incurred above the agreed upper price cap will be their responsibility and we as the client will have to pay nothing extra. They estimated the project will take 12-14 weeks. They started the project and assured us the NDA and Contract is getting sorted and they will send it over as soon as. Long story short flexsin Technology never honoured the contract and the price cap as the price started increasing past the price cap. It is now been 8 months since they started the project and they have not signed the NDA nor the Contract as agreed. We noticed they misspelt the names on the NDA and Contract. We asked them to rectify the spelling mistakes and they have refused asking us to Change the NDA that they wrote themselves to meet their interests. They are asking us to include on the NDA that UPwork will resolve disputes in relation to incorrect spellings on the paperwork and the NDA as if they are planning to make more mistakes. Up work is just a platform that brings developers and clients together, UPwork does not resolve spelling mistakes and unsigned paperwork. UPwork is NOT developing our software for us, we did NOT share the software information with UPwork, we shared information with Flexsins Technologies and above all Up work did NOT misspell or fail to sign the NDA or Contract, that was Flexsins Technologies mistakes to fix and NOT UPwork mistakes to fix. They are now asking to write another contract for more money probably with another price cap just to lure. They have agreed to send the assets back to us immediately. Updates of this review to follow on here, twitter, LinkedIn, IG, TikTok, and any other platform.
Liam Durbin's Review Sourced from Google
I have had a great experience with Flexsin. My small business is a bit of a niche (horse racing) but the team at Flexsin worked very hard to understand the nuances. Very impressive breadth of skills on the team. The support work they do for my small business on a monthly retainer has been good, as has their project work on a mobile app.
Dave Reynolds's Review Sourced from Google
I've been with Flexsin for 3 years now, and it's a great place to work. Talented technical staff and good management. After years of providing IT staffing solutions for US based companies with local personnel, I'm now able to save our clients a LOT of money by using the resources of our talented team of resources at our offshore development center instead.

Point of action made the process extremely simple and streamlined. From the moment I started working with them I knew they were the ideal fit for me and my website formation. I could not believe how awesome and professional my website looks. I would recommend them to anyone one hundred times again!
Zach Witt's Review Sourced from Google
We've been with POA Marketing for a few months now and it's been a really great experience! We've been in business for about 8 years now and up until recently we have not done much at all regarding SEO and overall marketing web presence. After working with Dani and Eliz for about 3 months, I'm blown away by how much we've accomplished so far! Already starting to notice our engagements go up with both our network and prospects, and also the data clearly shows it. Highly recommend this team to handle anything marketing related!

Digital Services Review from Paloma Anguiano
Overall I feel very confident working with Patrizia and Darius from Smart Site, they have given us clear explanations and accompanied us throughout the process for the growth of the brand. The attention to us is very fast and they advise us in an adequate way.
Digital Services Review from Brianna Porter
SmartSites impressed me from day one. They are knowledgable, kind, and most importantly keep things simple and streamlined so that even an SEO-newb like me can understand. Tiffany and Luna are my main points of contact and they are especially great! I would recommend to anyone looking for an agency to really take their website and digital presence to the next level.
PPC Review from Jim Curry
At first, a survey was conducted to gather company background, product information, target markets, etc. Next, accounts were established on various Google Business platforms, social media, etc. Then SmartSites created the ads and campaigns, and we were off and running in just a few weeks.

We have used HigherVisibility now going on 3 years. Our SEO rankings and eCommerce sales have been fantastic over that time span. More than I could [have] anticipated. This team knows what they are doing in the complex SEO and PPC world and are a huge asset to us. 3 years ago, we had basically 0 online presence. Now, we are consistently ranking #1 on Google for our best-selling products. (Verified via email)
