I collaborated with GIM for an SEO evaluation of my website. The audit was truly in-depth, and the points of attention – keyword suggestions – were all clear and accurate. During the session we had to evaluate the findings and improvement suggestions, the technicians were EXTREMELY INFORMATIVE and very enthusiastic. It is evident that they love their work, possess in-depth knowledge, and are genuinely eager to help, unlike a company you forget after payment. The after-sales support was excellent! Regarding the results, I implemented the changes they suggested, and already after 2 months, 5 important keywords are ranking on the first page. Furthermore, many keywords have moved up to the 2nd-3rd page, and there is a generally stable upward trend in Rankings, all for quality keywords. Extremely satisfied, I recommend them wholeheartedly, and I will certainly collaborate with them in the near future for even more specialized SEO services and with their advertising department. If Google had more stars, I would give them all!

We have been collaborating with GIM Greek Internet Marketing for almost 5 years with absolute success. I still remember the first communication I had with Karolos, who presented me with our collaboration plan through SEO management. The collaboration proceeded exactly according to the agreed cost and timeline, and soon the first results came to our company with a significant increase in site traffic and the phone calls we received. Throughout our collaboration, Karolos has always been by our side, both in the construction and upgrade of our site and in providing advice on any digital marketing issue. If you are looking for a reliable partner in this field, GIM should be your first choice!

GIM was recommended to me by a friend. Initially, I was quite skeptical about the reliability and nature of their work. I admit that many times I thought that yet another company promises results for easy profit. I decided to try and proceed step by step with caution because I was already disappointed and deceived by another company in the past. My opinion began to change cautiously after our first meeting. Organization, knowledge, confidence in their work, and explanation of the processes we would follow. The main element that gradually made me reconsider was that the same GIM executives led me to the simplest solution (and of course more economical) to proceed step by step towards the desired result. Today, after 3 years of successful collaboration, with absolutely correct and well-structured results, whatever they propose, I will simply give the "ok" to proceed.
Informed, specific, substantial, and effective.

When I heard about GIM's "consulting" service at a seminar, I participated without a second thought. I knew (or thought I knew) some things about my website, fit-4-all.gr, and I certainly wanted to learn from reliable sources what I should do, not generalities. Although hesitant about the outcome, from the first meeting I realized I was dealing with 100% professionals. Informed, specific, substantial, and effective. We improved all the shortcomings, and with the advice of Mr. Karolos Tsiligirian, the results were immediate. It is worth not 100%... but 1000% of every cent I spent. Thank you very much for the support, and in another "difficult" moment, I now know which door to knock on.
Consulting with Charles was truly a revelation for us.

I have been involved with the internet for 20 years, with my own e-shop since 2008. Despite the experience of all these years and collaboration with various individuals and companies, my site had several issues (technical and otherwise) that needed resolution, but I didn't know where to turn. Through research, my path crossed with Greek Internet Marketing. The discussion I had with Karolos showed me within the first few minutes that I had found what I was looking for, and this time I was not mistaken. My collaboration with them was exactly what I had always been searching for! Solutions were found for all the site's problems, and now everything operates perfectly. I have now found the partner and consultant I was looking for and would recommend him to anyone who asked. A model of professionalism!

It was also very helpful that we listened to and observed 4 customers who navigated our site and left their comments on their browsing experience. At GIM, we were treated with professionalism and they were punctual with delivery times. They were also very detailed and informative in the answers they provided to our questions during the meeting after receiving the audit. We highly recommend them!

Personally, GIM Greek Internet Marketing is one of the most reliable companies for managing online matters. Karolos Tsiligirian is one of the most skilled professionals in the internet sector, and all his associates are knowledgeable in their field, friendly, and always willing to resolve any potential issue. For my company's advertising, GIM has undertaken the full range of advertising campaigns on Adwords, Facebook & Instagram, as well as the SEO management of organic results. Their strategy, planning, and consistent actions daily confirm their true professionalism. In conclusion, I would unreservedly recommend GIM as one of the most reliable choices for any business that wants to build and advertise its website, achieving immediate results!

I reached out to GIM for help with understanding our marketing tactics a few months ago expecting to receive guidance on where to put what information on google searches. When I first spoke to Karolos, I felt very comfortable speaking to him and I felt he was really listening to the story of our business and where it is we are trying to go with it. I also realized just how much I didn't understand about where we were falling short.In the following weeks with Karolos' professional consulting and guidance, we have been able to improve our presence on line and are in the process of continuing to improve further.We are now on a much better track to making our business more successful. We really appreciate the help of the GIM agency and would recommend them to others absolutely.

This is the third website I've launched for my work. The first 2 were done by dear friends, based on the specifications I set and that's it. GIM is the only company that has scrutinized every letter on every page of the site from start to finish. The process took quite a while, we had multiple discussions and revisions upon revisions, and the advice from both Karlos and his associates played a significant role in the final result, which I am proud of and grateful for. Because I researched a lot before deciding, and without ANY exaggeration, it was what we call value for money. The product I purchased was clearly described in the agreement, with every detail, and the word that describes GIM is "professionalism."

I previously had a very bad experience with someone who was supposed to be an expert in website development. I came to GIM because I liked their previous work and was absolutely satisfied with their services! I particularly appreciated the prompt service and the feeling that I was speaking with people who truly know their job well. I will definitely recommend GIM to others!

At GIM, they earned my trust because I saw their interest in "listening" to my desires. The exchange of ideas resulted in the creation of an online store that truly sells. Based on their professionalism, I also entrusted GIM with the creation of a blog. I am confident in its success. Congratulations to the entire Greek Internet Marketing team for the work they do.
