All in One SEO noindex settings

Blue WordPress LogoThe All in One SEO WordPress plugin is a very popular plugin. Many install it so that they have the ability to customize their post’s page title. This is very useful to do from the SEO perspective. Your post title should be written for your reader and be catchy, your page title for your post should be more oriented towards keywords.

But the plugin has other settings that require attention. Out of the box the plugin configuration will noindex your category pages but not your tag pages. This isn’t necessarily what you want and I’ve had to fix a couple of blogs that had the default settings.

What does noindex do? It’s a special meta tag placed into your source code as an instruction to the search engine spider. To be accurate the tag created by the plugin is actually a noindex,follow. The follow bit is important, you want that.


noindex,follow tells the search engine spider to not place the page into it’s index (which feeds the search engine results pages) but to go ahead and crawl and follow any links on the page.

Why on earth would you not want your category (and tags, archive pages) in the search engine’s index? The more the better right? Well, no, not really. Many category, tags and archive pages just repeat all or part of the content that is already on the post pages. To Google and the other search engines, this is content that is duplicated and not interesting. Duplicate content within a single domain is a bad thing. It’s better to have 10 pages of unique content for Google to rank rather than 30 pages of duplicated content.

To add insult to injury, the way people use tags makes it worse. The ease of tagging causes many tags to be created (I’m just as guilty – just check out my tag cloud). I’ve seen blogs where no tag was ever reused, people treat them almost like a shortened form of a title and will tag each post with 4 or 5 unique words. The problem with this is that this creates one page per tag with one post on it, repeated 4 or 5 times. If your blog has links to your tag pages (ie. through a tag cloud or shows them on your posts) and you left them indexed then the poor spider has to crawl through all these duplicates (/tag/banana … /tag/bread … /tag/recipe .. get the idea?). It will just give up and go away.

With one exception my recommendation is to noindex all three aggregate pages: category, tags and archives.

The exception is if you have written unique manual excerpts for your posts (they are different than your your main post) AND the excerpt is shown (many themes don’t show them). Then I would consider indexing your category pages (as they tend to be fewer of those than tags). At this point you should do some keyword research and use that to name your categories.

For a while I was hesitant about noindexing all three, it seems wrong to not give the spiders a “bridge” page to add context to your posts, but after some study, I checked all three boxes a while back. I’ve given some thought about implementing excerpts for this blog and turning off noindexing for categories. But I’m lazy, and I might just build some keyword rich static pages, which will probably rank better anyway.

I am looking everywhere for a decent article which discusses the merits and results of what to index and what to noindex. This article was promising until I realised that you haven’t waited to see the results of noindexing all three?

What happened? Did your posts win more traffic? Did you change it back? At current all this tells the reader is that you decided to noindex all three, but not whether your site benefited from the change?

Any chance of an edit or follow up which updates us as to the positive or negative results of such a change?

Kathy Alice says July 12, 2011

Good question, yes, I should do a follow up to this post. I didn’t keep track of when I made the change exactly. Since I published this post traffic has been flat, but I know I changed it a few weeks prior. In the last 2 months my traffic has jumped up quite a bit but I wouldn’t attribute it to just this one change.

Brian says July 29, 2011

Good article.

I have a site where each post is an individual product, categorized by categories and tags. I hadn’t changed any of the default settings of the All in One SEO plugin until reading this article.

I have unchecked all noindex’s today so will keep an eye on this and provide some feedback if successful or not.

Kathy Alice says August 1, 2011

Thanks for the comment, I’ll be interested in your findings. I recently posted a summary of the changes/activities that has increased traffic to my blog. Noindex my tags was one of them.

Lavoro in Spagna says August 10, 2011

Hi, I had the same issue and question for my website. As many guide suggested at the beginning I choose no index for category, tags and archive, but I was struggling to rank for certain combinations of keywords which I only could get by allowing index for category. I did it, and I am actually seeing, even if the change is recent, that organic traffic for that category pages is already growing considerably.

I know I am facing a duplicate content issue doing that, but I also though:

1) every website, when growing, has almost no chance to avoid 100% duplication content

2) if I consider duplication of content the content I show to user in category pages, then I should noindex the home page as well, because what I show ther is just a snippet of my latest 5 entries!

So, my opinion is, according to your site architecture, to pick ONE between category OR tags and allow indexation if you need certain content to be displayed in a certain way and crewled for ranking purposes.

My 2 cents,

    Kathy Alice says August 12, 2011

    Definitely I would agree that you shouldn’t have both the tag and categories pages indexed.

Don Faust says March 31, 2012

Maybe I don’t get it. Isn’t that the reason that the plugin has the option “Canonical URLs”?

    Kathy Alice says April 1, 2012

    It could be an alternative. What would you set the canonical tag to? The home page? Keep in mind that the canonical tag is a hint (although Google definitely heeds it, Bing less so) not a directive like noindex so it’s a less strong signal.

javid says April 2, 2012

I want to know when category pages and tags created duplicates and you say they should not be indexed why then all the big news sites and popular blogs index all of their tags?
I can name as an example, why their ranking in Google is good, is it useful for them too?
Yours Sincerely

    Kathy Alice says April 8, 2012

    The one exception is when that page byitself is considered a viable resource for users. A top 100 blog listing page on fits that criteria and undoubtedly has a lot of links to it so yes it should be left as indexed. If you put some work into jazzing up your category pages and make them viable landing pages then keep them indexed. Thanks for the question it’s a good one..!

javid says April 26, 2012

Thanks for answering my previous question
I have my new WordPress tags indexed and removed them from Google index.
But with all the tags off my Google rate is 300 IP which was 3000 IP before.
I wanted to know whether this is normal and my visits from Google would increase again or what?
My site is
Best regards

    Kathy Alice says April 30, 2012

    I’m not sure what you mean by “IP” here. Your Google traffic might increase, it might not, unfortunately there are so many other factors involved.

javid says May 1, 2012

ip = visitors

    Kathy Alice says August 24, 2012

    Hi, site architecture is just one part of SEO. You have to write posts/pages with keywords that match what the searcher is looking for – hopefully with keywords that aren’t that competitive. And you need to promote via social media and linkbuilding. Hope that helps.

Thanks! I was not sure about no-indexing general informational and navigation type pages. I will now do this on our site. Good luck in 2017.

Anil says January 23, 2018

Which is better index or nonindex…if i am using nonindex showing error in search engine console
like Submitted URL marked ‘noindex’

    Kathy Alice says January 25, 2018

    Index the pages that you think are ideal for searchers to land on. Noindex the pages that are duplicate, thin or otherwise not good for searchers to see as the first page of your site. The new Google Search Console will show you pages that are not indexed because of the noindex tag. This is not an error but rather information for you to evaluate whether it is appropriate that these pages are not in the Google index.

Edwin O. Polini says April 19, 2018

Hello Kathy,
I must say I like the simplicity of this post. Your writing style makes it easy to understand the subject at hand.

I’ve been reading on best practices regarding noindex and nofollow in general, and I’m still somewhat torn about not indexing categories, but, you make a very good point on making them a valuable landing place, so I believe I might do that with keywords.

Keep up the good info!

    Kathy Alice says May 6, 2018

    Yes, if you are willing to put some SEO love into your category pages then leave them indexed. Thanks for your kind words on my writing style!

Ezulix Software says November 26, 2018

Good Article but still ,my issue is not fixed. I have a wordpress theme, my problem is that, my home page is indexing but other of my pages are not indexing and they are showing “NoIndex, Follow” tag in the header. I don’t now how to fix it, Please Help me to solve out this.

    Kathy Alice says February 5, 2019

template trip says June 15, 2019

how do i category page index in to wordpress platform?

    Kathy Alice says June 17, 2019

    It depends on the plugin (and some cases theme) you are using. Look for settings that control the indexation of the page types.

Kanyi says June 16, 2019

A lot of tags on my website are indexed and when i search for my website link on Google, i see all tags no articles. I just noindexed my tags after reading your article.
