What is a URL Redirect?
In simple terms a Redirect is a process of forwarding one URL to another URL. It redirects users as well as search bots. In other words, when someone is trying to access URL www.abc.com , server will redirect user to the new URL. www.xyz.org
Types of Redirects
There are three types of redirects:
- 301 Permanent Redirect is the most common one, and is used in 97% of all cases and it’s the most SEO friendly way of redirecting pages. 301 redirects refers to the HTTP server response code which means “Moved Permanently”. 301 redirect is used.
- 302 Temporary Redirect – The requested URL resides temporarily under a different URL. It’s only used if you want to move content temporarily for a short period of time.
- META refresh is a page level redirect, meaning that the page instructs the browser to refresh using a different URL. It may look like a redirect, but in reality it’s just a browser refresh. It’s not SEO friendly and it’s not recommended in 99.9% all redirect cases.
When it comes to campaign tracking, Google Analytics is very good at doing that. Campaign tracking is relatively easy, but in some cases campaign tracking parameters may cause duplicated content problems, so in order to prevent duplicated content problem I recommend adding hash marks.
During a panel Search Engine Land’s Editor-In-Chief, Danny Sullivan and Microsoft’s Senior Product Marketing Manager of Bing at SXSW named Dear Google & Bing: Help Me Rank Better! Matt Cutts announced that “in the next months or few weeks” Google is planning to release a penalty for over-optimized sites.
