Intersecting crossing street-car tracks.

What is a 302 redirect?

Also taken from Aimee Jarboe’s information to response codes, this can be a short-term redirect that acknowledge the consumer’s request and says, “I discovered the knowledge you need, however it’s someplace totally different in the meanwhile.”

Google’s John Mueller has said that Google doesn't penalize for 302 redirects, and the index will ultimately deal with a 302 as a 301 if it stays lengthy sufficient.

However do be cautious (as with all technique of redirection) when implementing 302.

What is a canonical tag?

The rel=”canonical” tag may be added to the HTML of any webpage. It principally tells serps that, when there are a number of variations of the identical webpage content material, to solely index a selected model.

When would I use a canonical tag?

You also needs to use a canonical tag if in case you have duplicate content material in your website. To use an instance from Brad Miller…

If you might have two (or extra) pages each itemizing the identical collection of merchandise. One lists them alphabetically and the opposite by worth. They include the identical content material, however have totally different URLs.

If you have been to go away each pages alone, Google would index each, however decide which one it believes is probably the most related and will filter the web page you truly need to be showing in search outcomes pages.

By putting rel=”canonical” on the alphabetical web page telling the various search engines that the worth web page is your most popular selection, you keep away from all these points.

What’s the distinction between a 301 redirect and a canonical tag?

With a canonical tag, all variations of a bit of content material can be found for anybody to see, however they aren’t listed. Nor do canonical tags cross any rating increase to the unique article.

With a 301 redirect, the unique web page will not exist (in a fashion of talking) and any hyperlink authority might be handed on.

The rel=”canonical” attribute is usually incorrectly used as a 301 substitute. Rather than bodily sending customers to a newer or related web page, rel=”canonical” is a sign that’s purely for the good thing about the various search engines.

Problems with canonical tags

As Brad Miller states…

Though most search engines like google state that they pay shut consideration to rel=”canonical”, they aren’t obliged to comply with them. This means that you could be nonetheless see your duplicate pages sometimes being proven forward of your most popular web page in some SERPs.

The canonical tag can also be generally misused. Unless a web page incorporates a substantial chunk of duplicate content material, the rel=”canonical” tag in all probability shouldn’t be used.

Another misuse happens with a number of, associated pages. If you’ve written an extended weblog publish however determined to interrupt it up into 5 pages, you might be tempted to incorporate a rel=”canonical” tag pointing again to the primary web page of the collection.

However utilizing rel=”canonical” tells the search engine that the content material on every of the pages is nearly equivalent and that you really want it to all the time present the primary web page in search outcomes. This will successfully cease pages P-H from ever being proven, even when they carry a excessive degree of relevance and authority for that particular search.
