Jennifer LaNasa President at LaNasa Realty

WordPress Review from Jennifer LaNasa
LaNasa Realty Inc has been around for a long time in the New Orleans area. I reached out to Online Optimism to update my website and tell the story of my family history in the New Orleans area and how I have been involved in this history as a Real Estate Broker early on in my career. I needed a web site to show that LaNasa Realty does all aspects of Real Estate from Commercial Sales and Leasing to Residential Sales, and Rentals. Short term rentals have become very popular in New Orleans.

Some of the results we've seen since our work with Online Optimism began is a higher level of engagement with our members. The communication with Online Optimism has been fantastic. They have been so responsive to our needs, to our questions, to understanding what it is we are trying to do and accomplish with our website. They've gone above and beyond communicating with us.

The people at Straight North were so organized and efficient. Although we ultimately had to go in a different direction due to a change in design needs, the discovery process was very smooth. They devoted significant time to understanding what we needed from the project, and we greatly appreciated it!

Jenny S's Review Sourced from Google
Working with Straight North was an incredible experience from start to finish! When I started looking for web designers, I narrowed it down to four companies, and Straight North was the only one who really took the time to get to know me, our business, and why our goals matter. That personal connection made all the difference.Once we got started, I was blown away by the thought and detail that went into every part of the process. What stood out the most was how open and receptive the team was to my feedback. I truly felt like a part of the process, not just another customer.Our new website is absolutely stunning and perfectly captures who we are and what our brand stands for. I couldn’t be happier with the finished website or with the experience of working with Straight North.Building a great website is truly a collaborative effort, and I’ve learned that the more you put in, the more you get out. I encourage anyone working with Straight North, or any design team to be open, share your vision, and really take the time to engage in the process. The result will be worth it, I promise!Thank you, Straight North, for an amazing experience and a website that we’re so proud of!

Sarah McKinley Review from Google

Sarah McKinley's Review Sourced from Google
For the past 20 years, our company has been honored to help some of the world's best firms restructure sales and marketing divisions.We had engaged Alliance Interactive to redesign a 200-page website with functionality improvements; the scope of work was massive.At the time, our website ranked well and with sufficient conversion rates, but it needed to be modernized.However, it was imperative that conversion rate, branding and search engine results be maintained.Therefore, we began looking for digital marketing companies to assist with a complete redesign.For context, we budgeted about $35,000 for the website redesign and overhaul project. Therefore, we had many digital marketing firms to choose from.After interviewing about a dozen, we ended up choosing Alliance Interactive. They blew away expectations.Our project manager was extremely smart and innovative. He learned our business advantages very quickly and made great suggestions. Alliance Interactive made our site look very creative, yet kept it user-friendly.The visual layout was artistic, yet professional. We could not have been happier. Very smart investment on our part and thank you to the Alliance Interactive team.

Our existing website was constantly breaking and had plenty of issues whenever you wanted to update it. Alliance Interactive redesigned our website, switched our hosting provider and helped optimize the speed of the site. Our operations are running much smoother.
