a week agoI would not recommend! The promises are great but the deliverables are mediocre at best! The website delivered was subpar from the beginning and when changes and updates were requested they were slow to implement (6 months to make changes!!). The communication was spotty and the account manager would take forever to respond (usually after many probes for an update). I cancelled after less than a year and refused to pay for an unfinished product. They will just hire a law firm to place a judgement against you. DO NOT USE.2 months agoI am beyond impressed with the exceptional service provided by 1SEO, particularly their skilled developer, Dan Fox. His dedication, expertise, and creativity truly shone through in the design, development, and launch of our new Crisafulli Bros. Home Services website.Dan not only met but exceeded our expectations, seamlessly translating our vision into a user-friendly and visually stunning website. His attention to detail, technical proficiency, and proactive communication made the entire process a breeze. We appreciate the collaborative approach that 1SEO and Dan took in understanding our brand and goals, resulting in a website that not only reflects our services but elevates our online presence. Even after the launch, whenever we need anything adjusted Dan responds within minutes, always making sure our needs are met.
Kudos to Dan and the entire 1SEO team for their commitment to excellence in website development and digital marketing! We couldn’t be happier with the results.
a month agoStephanie Cosma and her team were a pleasure to work with. The team is very knowledgeable and we saw success with our SEO and PPC performance vs the prior year. We had some issues with Google and with our website (which were not 1SEOs fault) and their sense of urgency and responsiveness to correct the issues was top of game.2 months ago1SEO is like having friends in the digital realm who are persistent on delivering results.What sets them apart is the awesome team behind the scenes. I’ve personally gotten to know their team and let me tell you, they’re not just wizards with algorithms, they’re genuine, fun, and totally approachable.
We look forward to growing our partnership with 1SEO!
3 weeks agoAbsolutely the WORST agency we have ever worked with. We paid in full for a 6 month strategy over a year ago and have yet to see a single page implemented correctly. All you will receive from 1SEO are empty promises and excuses why things are not completed. Stay away from this company if you actually care about your business growing.
