I hired the company www.kcoresys.com. I needed to optimize the keywords and tags. When I chatted with the agent, he told me that it would take 10 days or a little bit more. But he assured me that the whole process wouldn’t take 2 weeks. It was great in theory, but in reality I checked my website two weeks later and the content was the same. Nothing was done. I sent emails and asked how long I needed to wait, but still no response.
