As you know that SEO is important. Every website needs a better SEO to get new viewers and potential customers to move their business to next level. If you need to get more customers and visitors, you need to focus on your target market. If you are focusing on the spesific country, it is always better to get dedicated server or VPS from the related country. Language of your website is also important. If you are focusing on the Turkey market and your customers are speaking Turkish, using Turkey Dedicated Server will always give you the best results. When pagespeed increases, client can reach your website quicker.
If your needs and budget is limited, you can also get virtual private servers. Because of the virtualization, you will use limited resources on the dedicated server and it helps you to make saving. You can add your savings to your advertising budget and it will help you to reach more people. But of course when you need more resources, you need to get dedicated servers anyway. Principle is similar with the dedicated servers, closer is always better. If you are focusing on Turkey market, get a Turkey VPS; If you are focusing on Swiss market, get a Switzerland VPS.
