      App Marketing Review from Oleg Naumov

      We were looking for a company that could promote our delivery app. We had a really hard KPI and special target audience so we needed a professional agency for effective ad campaigns.By the right targeting, messaging and catchy creatives the conversion increased and CAC decreased by 20%. As a result, the volume increased by ~ 700%.We had a rather hard goal to achieve, and we were surprised how easily the Mobio team handled the task.

      We needed a company that could promote our mobile app. Our main goals were to acquire more relevant users for our app and find alternative sources for that instead of classic ones.Mobio Team did a great campaign as a result of which we found our relevant audience and target with CPA close to KPI.

      App Marketing Review from Sergey Alyautdinov

      One of the main tasks of promotion was to motivate and encourage users who installed the application, but used it only once or never at all, to place an order. An advertising campaign with a multi-format showed good results: it was possible not only to achieve KPIs, but also to exceed them. CPO decreased by 51%, CR increased by 15%.Mobio really does what they promise. They have a lot of experience in our industry, so everything they did was 100% right and well-planned.

      I have the tech savvy of a timer traveler from the Roman Empire, so when I determined that I needed a professional website, there was little chance that I'd be able to figure out how to create one using one of the many DIY web-design templates out there.Moreover, the only things I have LESS of than tech savvy are 1) design savvy and 2) a ton of money to throw at the project.So it seems almost a gift from the stars that I happened upon Sujatha, Valerie and PureLynx. The team is delightfully friendly, personable and skilled in sitting down with someone like me, holding my hand through the design and implementation process and not only translating my "vision" into reality, but improving upon that vision in the process.And it goes without saying that they're way on-top of the tech and security stuff that baffles me--which makes me feel safe, confident and like my site and I are in sturdy hands.And speaking of that site, I'm so over-the-moon with it that I'm not only sending it to every potential client I can think of; I'm sharing it with, heck, old piano teachers, ex-boyfriends and the like. It's my new pride and joy. :)And it wouldn't have happened without PureLynx. To the extent that a "friendly neighborhood web-development firm" exists, PureLynx is the very model of it. I'm so glad to have them around!

      Our needs for a website are relatively simple, as we’re a business-to-business startup: we need portals for announcements, a growing line of products, and our capabilities. Purelynx created our site using WordPress.When we updated our logo late last year, we hired a graphics designer to develop the logo from the initial concept and then implement it on the website. As he was also a web developer, we switched site management from Purelynx to him. Unfortunately, the branding update stretched from weeks to months and, once implemented, had frequent major problems, from the site going down to images disappearing.In a panic, we switched back to Purelynx. Sujatha jumped in to quickly solve the issues, multiple times, until the site was rid of the nefarious bugs that had plagued us.Kudos to Sujatha for the quick response to restore the site. We’ll continue to use Purelynx to maintain it and for future evolution.

      ROSE RIVERS's Review Sourced from Google

      First & foremost this testimonial is long overdue, my husband & I attempted to create a website on our own using a "free" web design service. It was much more difficult than advertised to create our own website & even more difficult deciding what to do next on how to drive customers to our site. We knew we were over our heads & so began our search for professional web design/marketing help. We met with Sujatha from PureLynx & immediately felt confident with her ideas for improving our website. Thus far PureLynx has surpassed our expectations & created a website that not only benefits our business but our customers as well. We would highly recommend PureLynx for all your website & marketing needs. ~ The Sari-Sari Shop & Bin Detailer Team

      Terrible experience — no cashback and poor customer supportI placed two Lightbox Jewelry orders through Rakuten yesterday morning, expecting 3.5% cashback as advertised. However, Rakuten failed to track both purchases.When I attempted to manually add the orders later in the day, I found that Lightbox Jewelry had been completely removed from Rakuten’s site — no store page, no link, nothing. I contacted customer support multiple times, but the responses were vague, unhelpful, and ultimately useless.This experience reflects poorly on Rakuten’s reliability and integrity. Removing a store without warning right after a promotion, then refusing to honor cashback, is unacceptable. Very disappointed.

      SHADY business practices. Rakuten slid a pop up into my account that stated "don't forget, you still have $ to spend at Victoria secret" as if i had a refund credit. Beware... what they don't tell you, is this money is deducted from your cash back, which I'm sure is just a tactic to enhance their vendor contracts....very disappointing
