      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.

            Customer Reviews on Product Page / Pagination / Crawl 3 review pages only

            reviews pagination crawler disallow

            Hi experts, I present customer feedback, reviews basically, on my website for the products that are sold. And with this comes the ability to read reviews and obviously with pagination to display the available reviews. Now I want users to be able to flick through and read the reviews to help them satisfy whatever curiosity they have. My only thinking is that the page that contains the reviews, with each click of the pagination will present roughly the same content. The only thing that changes is the title tags which will contain the number in the H1 to display the page number. I'm thinking this could be duplication but i have yet to be notified by Google in my Search console... Should i block crawlers from crawling beyond page 3 of reviews? Thanks

            Hundreds of 404 errors are showing up for pages that never existed

            For our site, Google is suddenly reporting hundreds of 404 errors, but the pages they are reporting never existed. The links Google shows are clearly spam style,  but the website hasn't been hacked. This happened a few weeks ago, and after a couple days they disappeared from WMT. What's the deal?

            Blog Page Titles - Page 1, Page 2 etc.

            Hi All, I have a couple of crawl errors coming up in MOZ that I am trying to fix. They are duplicate page title issues with my blog area. For example we have a URL of www.ourwebsite.com/blog/page/1 and as we have quite a few blog posts they get put onto another page, example www.ourwebsite.com/blog/page/2 both of these urls have the same heading, title, meta description etc. I was just wondering if this was an actual SEO problem or not and if there is a way to fix it. I am using Wordpress for reference but I can't see anywhere to access the settings of these pages. Thanks

            Can you 301 redirect a page to an already existing/old page ?

            If you delete a page (say a sub department/category page on an ecommerce store) should you 301 redirect its url to the nearest equivalent page still on the site or just delete and forget about it ? Generally should you try and 301 redirect any old pages your deleting if you can find suitable page with similar content to redirect to. Wont G consider it weird if you say a page has moved permenantly to such and such an address if that page/address existed before ? I presume its fine since say in the scenario of consolidating departments on your store you want to redirect the department page your going to delete to the existing pages/department you are consolidating old departments products into ?

            Google's "cache:" operator is returning a 404 error.

            I'm doing the "cache:" operator on one of my sites and Google is returning a 404 error. I've swapped out the domain with another and it works fine. Has anyone seen this before? I'm wondering if G is crawling the site now? Thx!

            Handling 301s: Multiple pages to a single page (consolidation)

            Been scouring the interwebs and haven't found much information on redirecting two serparate pages to a single new page.  Here is what it boils down to: Let's say a website has two pages, both with good page authority of products that are becoming fazed out.  The products, Widget A and Widget B, are still popular search terms, but they are being combined into ONE product, Widget C.  While Widget A and Widget B STILL have plenty to do with Widget C, Widget C is now the new page, the main focus page, and the page you want everyone to see and Google to recognize. Now, do I 301 Widget A and Widget B pages to Widget C, ALTHOUGH Widgets A and B previously had nothing to do with one another?   (Remember, we want to try and keep some of that authority the two page have had.) OR do we keep Widget A and Widget B pages "alive", take them off the main navigation, and then put a "disclaimer" on the pages announcing they are now part of Widget C and link to Widget C? OR Should Widgets A and B page be canonicalized to Widget C? Again, keep in mind, widgets A and B previously were not similar, but NOW they are and result in Widget C. (If you are confused, we can provide a REAL work example of what we are talkinga about, but decided to not be specific to our industry for this.) Appreciate any and all thoughts on this.

            What SEO considerations for multiple languages on a single page?

            I am working on a language teaching site for Chinese speakers learning English. I consider myself above average when it comes to basic SEO issues, but all I know here is that Google doesn't like multiple languages on a single page. Without getting into too many details, both Chinese and English text will appear on the same page with links, tags, phonetic spellings, etc. I'm hoping someone here knows the science about using the lang="zh" xml:lang="zh" attributes within text and the effects on ranking for text within the declarations. And it'd be great if there was clarification on the link juice passed using the hreflang attribute for both internal and external links. Also, of course, any info on using both English and Chinese characters in the URL would be most helpful. A heads up on any other language specific SEO issues would also be much appreciated. My goal is to get the most out of both languages per page in terms of ranking.
