hi, If i change the hosting of my site, will it has some impact on Google PR. will it be bad or no impact on it. need your advice on this issue. thanks.
Not Really.. It Does Not Matter Although it takes some time to shift from one server to other, Almost 48 Hours to shift from one other.. It Does Not effect your PR until or unless you change your permalinks, If URL remains same then All is Well...
Well since google now takes into account the page speed, if you're moving to a faster server then you might have a better google ranking. However dont count on that too much.
If it effects how your website loads it could impact ranking. If the page loads faster it may load faster, if it loads slow or is down it will negatively impact ranking.
