The refreshing time of a webpage can be define by using html tag HTTP-EQUIV “REFRESH”. It is used to refresh the page in a certain period of time (1 min, 2 min etc) or redirect user to another webpage.
But it is not a good method because many search engines didn’t like this method, so it will be better to add a clickable link on webpage instead of html tag HTTP-EQUIV “REFRESH”.
An example of a refresh value is:
<meta http-equiv="refresh" content="value">
Below tag will redirect user to another webpage automatically after 5 seconds
<meta http-equiv="refresh" content="5; ,URL=http://vishmax.com/">
