The user enters one page, but it is updated immediately or after a certain period of time. This method was often used in the creation of doorways, so it is not surprising that search engines struggle with the Meta Refresh redirect.
<meta http-equiv=»refresh» content=»7″>
Or like this:
<meta http-equiv=»refresh» content=»2;URL=http:/site.ru»>
In the first case, HTML redirect will be performed in 7 seconds. In the second case, the page will be updated in 2 seconds, and the user will see a completely different site. Search engines punish such actions with filters and even bans.
Google’s lead analyst John Muller writes that using Refresh can cause other content to be indexed. The bot perceives this meta tag as a redirect and, as a result, scans the information after it has been updated.
Some webmasters used this redirection to cheat search algorithms. After all, the information is processed only at the browser level, and therefore is not transmitted to the server. Indeed, most search engines do not index JS redirects, but not Google. This bot is able to recognize such a redirect.
In this case, you will redirect the user from the original page to serpstat.com. If you add the function:
setTimeout(‘location=»http://serpstat.com»;’, 3000 );
You set the timeout to 3 seconds before the redirect to the other site happens.
The situation here is identical to the use of the Refresh meta tag. Such redirects are justified only in one case: if after a certain user action is necessary to make a double redirect to improve behavioral factors.
For example, in the online store after the purchase, a 301-redirect triggers to the gratitude page or further instructions. After that, it is advisable to direct the user to the home page or a page of subscriptions. Double 301-redirect affects badly on SEO-optimization. Then it is allowed to use the Refresh tag. In other cases, it is better to abandon such manipulations.
Any deception of the user or search engine is not acceptable for SEO. It is instantly recognized by search engines. The site should be excluded from the search or lowered its position for this action. So, it can be extremely difficult to restore the honest name of the domain after such an error.
If the site at least once came under the filters of search engines, even after their removal, the resource will be worse to promote. As a result, you will have to register a new domain.
