![]() Due to abuse by spammers and suspicion by the search engines, 301s between domains sometimes require more time to be properly spidered and counted. Transferring content becomes more complex when an entire site changes its domain or when content moves from one domain to another. Other options for redirection, like meta refreshes, can be poor substitutes, as they may not as reliably pass the rankings and search engine value like a 301 redirect will. This process can be lengthier if search engine spiders rarely visit the given web page, or if the new URL doesn't properly resolve. The engines will carry any link weighting from the original page to the new URL, as below:īe aware that when moving a page from one URL to another, the search engines will take some time to discover the 301, recognize it, and credit the new page with the rankings and trust of its predecessor. ![]() Search engines interpret this to mean that not only has the page changed location but that the content-or an updated version of it-can be found at the new URL. Serving a 301 indicates to both browsers and search engine bots that the page has moved permanently. There are multiple options for doing this, but in general, the 301 redirect is preferable for both users and search engines. The first common example of this takes place with a simple scenario: a URL that needs to redirect to another address permanently. When doing this, it is critical to observe best practices in order to maintain SEO value. It is common practice to redirect one URL to another. Take a 30-day free trial on us and see what you can achieve: ![]() Moz Pro's Site Crawl feature uncovers urgent issues such as redirect chains, temporary redirects, and meta refreshes so you can fix them fast. Identify critical redirect issues using Moz Pro They are usually slower, and not a recommended SEO technique. They are most commonly associated with a five-second countdown with the text "If you are not redirected in five seconds, click here." Meta refreshes do pass some link equity, but are not recommended as an SEO tactic due to poor usability and the loss of link equity passed. Meta refreshes are a type of redirect executed on the page level rather than the server level. Since it's essentially impossible to determine whether or not the search engines have identified a page as compatible, it is generally best to use a 302 redirect for content that has been temporarily moved. ![]() The exception to this is when content is really moved only temporarily (such as during maintenance) AND the server has already been identified by the search engines as 1.1 compatible. While the major crawlers will treat it like a 302 in some cases, it is best to use a 301 for almost all cases. 307 moved temporarilyĪ 307 redirect is the HTTP 1.1 successor of the 302 redirect. This is because while in theory both 302s and 301s can both pass the same amount of link equity, there are cases where a 301 might pass a stronger canonicalization signal to Google. For cases in which the redirect truly is temporary, a 302 may be the most appropriate. Use 302 redirects when the URL of a resource is changed temporarily. Some of Google's employees have indicated that there are cases where 301s and 302s may be treated similarly, but our evidence suggests that the safest way to ensure search engines and browsers of all kinds give full credit is to use a 301 when permanently redirecting URLs. In most instances, the 301 redirect is the best method for implementing redirects on a website. 301 refers to the HTTP status code for this type of redirect.
