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.

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?
For content material syndication, which is the tactical republishing of an article on one other third-celebration web site. This notably helpful for those who’re a smaller writer or an up-and-coming author who needs a bigger viewers.
The canonical tag on the republished article ought to hyperlink again to the unique article and inform search engines like google and yahoo to solely index that model.

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.

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.
