I recently move my websites to new server with new IP's and after that traffic goes down even searches from Google goes down. Is changing server or IP address impacts SERP's & traffic?
Yes it effects in ranking..if you want any site rank from Australia, then host it from Australian server, you can see the improvement, you ca do it for any country
Remember to always set your desired country on Google's webmaster tools. It will only affect ranking if you're placed on slower, less-responsive servers, everything else is easily fixable.
The server location is still same i.e. UK.....The number of visitors came from Google goes down day-by-day after changing the server.....What to do???
IP address do influence your SERP. Because most of local search engine prefer local host with local IP address and give them priority benefit in SERP. That is why people always encourage people that you need to know where is your target market and you need to host where near to them .
