Extra indexed pages from my blog in wordpress

[AlirezaHamidian]

I have a blog on my site which is in WordPress. When you publish an article it creates a couple of urls such as tags, author, category, month, ... . So when you look for indexed pages you see tons of pages for the blog. Does it hurt the SEO. If yes how I can sort it out,

Hello,

Yes it does hurt your SEO in terms of creating an authoritive web site. Wordpress is an over-optimisation nightmare if you leave the default setting on. It is a small issue you can solve by changing some of the setting in Yoast SEO plug in. have you installed this plug in? If not, do it and once you have done this do the following:

On the general setting: Tick the box "Noindex" on the sitewide meta setting 
On the post type setting: tick noindex/follow on the Meta Robots under the MEDIA section
On the taxonomy setting: tick noindex/follow  on the meta robots under the TAGS section
On the author archive: tick noindex/follow and Disable author archives under the author archive section. Tick ONLY the noindex/follow under the data archive section

On the XML SITEMAP setting:

tick media on "Exclude post types" - tick tags and format under the Exclude  Taxonomies section.

You should be ok after that!

ps. by tick I mean select

Hope this helps!

Hi Yiannis,

Many thanks for the time and detailed answer. I just set them all. Can you give me an idea that now what happens to the pages which are already indexed. Would they be automatically adjusted or I need to do fix them.

Not a problem mate, happy i helped.

You are in a good shape and do not need to do anything, Google will noindex those pages sooner or later. Just carry on with your onpage/off page SEO
