Error: Missing Canonical Tag But URL is not a webpage it is a PDF document, is this fixable?

@ahmadmdahshan There's two answers to this. One is that whilst it's best practice for all URLs to have a canonical (even if it's self-referencing), if this resource has no duplicates, it's not mandatory. The other is that yes, you can add a canonical tag to a web page. You'd have to do it at the HTTP header level. https://developers.google.com/search/docs/crawling-indexing/consolidate-duplicate-urls#rel-canonical-header-method

Optimization expert suggesting we add Canonical tag to every page on site

canonical technical seo

Hi guys, We're currently launching a new page, and we have an optimization and technical SEO expert (highly rated on Upwork, very intelligent, has solved complicated issues in the past and improved our Core Web Vitals greatly) suggesting we put canonical tags on every page of site, pointing to itself (other than the case of where canonicals should point to other page, we have those listed separately. Do you guys see a benefit to this? Could it harm us? He says large retailers do this, couldn't quite glean the benefit from it though. Current site ranks well and isn't set up like this. Any insight would be much appreciated! Thanks!

"Duplicate without user-selected canonical” - impact to Google Ads costs

google ads canonical

Hello, we are facing some issues on our project and we would like to get some advice. Scenario
We run several websites (www.brandName.com, www.brandName.be, www.brandName.ch, etc..) all in French language . All sites have nearly the same content & structure, only minor text (some headings and phone numbers due to different countries are different). There are many good quality pages, but again they are the same over all domains. Current solution
Currently we don’t use canonicals, instead we use rel="alternate" hreflang="x-default": <link rel="alternate" hreflang="fr-BE" href="https://www.brandName.be/" /> <link rel="alternate" hreflang="fr-CA" href="https://www.brandName.ca/" /> <link rel="alternate" hreflang="fr-CH" href="https://www.brandName.ch/" /> <link rel="alternate" hreflang="fr-FR" href="https://www.brandName.fr/" /> <link rel="alternate" hreflang="fr-LU" href="https://www.brandName.lu/" /> <link rel="alternate" hreflang="x-default" href="https://www.brandName.com/" /> Naturally this si reflected in ""Duplicate without user-selected canonical” . Issue
We create the same ad in Google Ads for 2 domains. So the content is mostly identical, ads are identical, target URLs differ only in domain. Yet Google Ads “Quality score” is different (10/10 vs. 6/10) and “Landing page experience” is very different (Above average vs. Average). Some members of our team think lower “Landing page experience” increases the Google Ads costs, which I personally don't believe, but I want to double check. Question: Can “Duplicate without user-selected canonical” issue decrease the “Landing page experience” rating and as result can it cause higher Google ads costs? Any suggestions/ideas appreciated, thanks. Regards.

Should we set up redirects for all deleted TAGS?

We recently found our site had 65,000 tags (yes 65K). In an effort to consolidate these we've started deleting them. MOZ is now reporting a heap of 404 errors for tag pages. These tag pages should not have links to them so not sure how come they're being crawled. Any suggestions from experience in this area would be useful.

Meta HTML tag code

I have been instructed by Moz that I have some missing meta description tags; however, this is what comes up when I searched for more help on this site: "The proper coding for a meta HTML tag is These Meta descriptions can be nested anywhere in the element." Obviously the actual coding is missing... so can anyone tell me what the proper coding for a meta HTML tag is? Thanks!

Rel Canonical tag using Wordpress SEO plugin

Hi team I hope this is the right forum for asking this question. I have a site http://hurunuivillage.com built on Wordpress 3.5.1 using a child theme on Genesis 1.9. We're using Joost's Wordpress SEO plugin and I thought it was configured correctly but the Crawl Diagnostics report has identified an issue with the Rel Canonical tag on the sites pages. I have not edited the plugin settings so am surprised the SEOMoz Crawl has picked up a problem. Example: Page URL is http://hurunuivillage.com/ Tag Value http://hurunuivillage.com/ (exactly the same) Page Authority 39 Linking Root Domains 23 Source Code Considering the popularity of the plugin I'm surprised I have not been able to find tutorials to find what I'm doing wrong or should be doing better. Thanks in advance. Best Nic
