      Hello all,

      Something strange happened with my blog site.

      I recently signed to MOZ tools.

      Initially everything was fine, but during my last crawl I got loads of 404
      pages.

      Few days ago I was tweaking some settings in SEO plugin according to this post https://a-moz.groupbuyseo.org/blog/setup-wordpress-for-seo-success

      What I noticed was that 404 pages were coming from my blog posts, but for
      some reason category was missing in those posts.

      For example this link is 404
      https://a-fotografy.co.uk/inchcolm-island-wedding-photography-bailie

      The one with category is

      https://a-fotografy.co.uk/wedding-pictures/inchcolm-island-wedding-photography-bailie/

      So basically for some reason category was missing.

      Please let me know how can I fix this instead of doing hundreds of
      redirects now.

      Thank you,
      Regards,
      Armands

        Hi,

        Thanks for response. So I went back and unchecked Strip the category base (usually /category/) from the category URL option and also

        Redirect attachment URLs to parent post URL. option.

        Hope this will solve the problem.

        Thanks,

        Regards,

        Armands

          From your description, it appears that when you were tweaking your Yoast SEO settings, you changed the permalink structure in the WP Dashboard's Settings > Permalinks section from www.domain.com/�tegory%/%postname%/ to just www.domain.com/%postname%/

          Doing this causes all the URLS for all posts on your site to change, which means all the original URLs are no longer correct and result in 404s.

          Your two options are:

          • reset your permalinks back to their original structure, and redirect whatever new posts were created since the initial change back to the /category/postname URLs
          • leave the new permalink structure in place and add a blanket rewrite rule in the htaccess file to redirect all the old post URLs to the new structure without the category. (Done properly, only one redirect is needed to handle all the post URLs.)

          Personally, for improved site architecture and to keep from having all your existing posts run through redirects, I'd opt for the first option above.

          Hope that all makes sense?

          Paul

          P.S. Make certain you have a current backup of the site before making any further changes, just in case.

            What do you do with product pages that are no longer used ? Delete/redirect to category/404 etc

            We have a store with thousands of active items and thousands of sold items. Each product is unique so only one of each. All products are pinned and pushed online ... and then they sell and we have a product page for a sold item. All products are keyword researched and often can rank well for longtail keywords Would you :- 1. delete the page and let it 404 (we will get thousands) 2. See if the page has a decent PA, incoming links and traffic and if so redirect to a RELEVANT category page ? ~(again there will be thousands) 3. Re use the page for another product - for example a sold ruby ring gets replaces with ta new ruby ring and we use that same page /url for the new item. Gemma

            How big is the problem: 404-errors as result of out of stock products?

            We had a discussion about the importance of 404-errors as result of products which are out of stock. Of course this is not good, but what is the leverance in terms of importance: low-medium-high?

            Expired domain 404 crawl error

            I recently purchased a Expired domain from auction and after I started my new site on it, I am noticing 500+ "not found" errors in Google Webmaster Tools, which are generating from the previous owner's contents.Should I use a redirection plugin to redirect those non-exist posts to any new post(s) of my site? or I should use a 301 redirect? or I should leave them just as it is without taking further action? Please advise.

            SEO value of InDesign pages?

            Hi there, my company is exploring creating an online magazine built with Adobe's InDesign toolset. If we proceeded with this, could we make these pages "as spiderable" as normal html/css webpages? Or are we limited to them being less spiderable, or not at all spiderable?

            Increase 404 errors or 301 redirects?

            Hi all, I'm working on an e-commerce site that sells products that may only be available for a certain period of time. Eg. A product may only be selling for 1 year and then be permanently out of stock. When a product goes out of stock, the page is removed from the site regardless of any links it may have gotten over time. I am trying to figure out the best way to handle these permanently out of stock pages. At the moment, the site is set up to return a 404 page for each of these products. There are currently 600 (and increasing) instances of this appearing on Google Webmasters. I have read that too many 404 errors may have a negative impact on your site, and so thought I might 301 redirect these URLs to a more appropriate page. However I've also read that too many 301 redirects may have a negative impact on your site. I foresee this to be an issue several years down the road when the site has thousands of expired products which will result in thousands of 404 errors or 301 redirects depending on which route I take. Which would be the better route? Is there a better solution?

            Home Page .index.htm and .com Duplicate Page Content/Title

            I have been whittling away at the duplicate content on my clients' sites, thanks to SEOmoz's pro report, and have been getting push back from the account manager at register.com (the site was built here and the owner doesn't want to move it).  He says these are the exact same page and he can't access one to redirect to the other.  Any suggestions? The SEOmoz report says there is duplicate content on both these urls: Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/index.htm Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/ Your help is greatly appreciated!

            404 crawl errors from "tel:" link?

            I am seeing thousands of 404 errors.  Each of the urls is like this: abc.com/abc123/tel:1231231234 Everything is normal about that url except the "/tel:1231231234" these urls are bad with the tel: extension, they are good without it. The only place I can find this character string is on each page we have this code which is used for Iphones and such.  What are we doing wrong? Code: Phone: <a href="[tel:1231231234](tel:7858411943)"> (123) 123-1234a>
