Does it do harm if you add a rel="canonical" tag on a page that doesn't need it?
-
If a page is clearly unique and there is obviously no canonical tag needed, does it hurt anything if one has been added?
-
In my opinion, you want the juice for each article to stay with each article. I wouldn't redirect all your article juice back to the main /blog page. For me, each unique page (and article) gets its own canonical link and one line = one set of information. Article about oranges, article about apples, both canonical links. You should only get juice from same or similar pages, such as
But not

hey matt, thanks for the response. let me ask you this. i have a blog page with a bunch of snippets, that when clicked, lead to the full articles, (each have their own custom page/url). if i want all the juice to go to the main blog page i don't want to have canonical tags on each individual post page, right?
-
Agreed. You page can sometimes end up with query parameters as well when people link to your site, and having the canonical in place will help you avoid having duplicate content.

It shouldn't hurt you if it doesn't need it but assuming you have www and non-www, wouldn't that part of the canonical always help anyways? By default, you would have
http://www.yoursite.com/notagneeded
http://yoursite.com/notagneeded
and if you're on most common CMSs,
http://www.yoursite.com/notagneeded/index.php or index.html or index.asp
It would actually be pretty rare to have a page with absolutely no use for rel=canonical but I don't see why it would hurt at all.

Do SEOs really need to care about trend in increase of voice search?
Hi all, Just browsing through the articles like "SEO trends in 2108"....I can see everyone mention about increase in voice search and attributing same to the SEO at top. But there is very less information on how to optimise for voice search....May be, they don't know what SEOs have to do exactly with voice search. Basically the input method is going to change on search and else remains same. This must be leading to increase of long tail searches and more search snippets to give an instant voice answer. What else has to be optimised to favoured in voice search? Thanks

Canonical and Sitemap issue
Hi all, I was told that I could change my homepage Canonical tag to match that of my XML sitemap, this sitemap is being generated for me automatically and shows the homepage as e.g. https://www.mysite.com/index.html, yet my Canonical tag has been set to https://www.mysite.com. Google currently shows as https://www.mysite.com/ being indexed, but https://www.mysite.com/index.html is not currently displayed in search results. Can someone please tell me if I should change the Canonical to the index.html version, or if I should do nothing, or remove the Canonical tag altogether? Thank you for looking.

Bing Indexation and handling of X-ROBOTS tag or AngularJS
Hi MozCommunity, I have been tearing my hair out trying to figure out why BING wont index a test site we're running. We're in the midst of upgrading one of our sites from archaic technology and infrastructure to a fully responsive version.
Web Design | | AU-SEO
This new site is a fully AngularJS driven site. There's currently over 2 million pages and as we're developing the new site in the backend, we would like to test out the tech with Google and Bing. We're looking at a pre-render option to be able to create static HTML snapshots of the pages that we care about the most and will be available on the sitemap.xml.gz However, with 3 completely static HTML control pages established, where we had a page with no robots metatag on the page, one with the robots NOINDEX metatag in the head section and one with a dynamic header (X-ROBOTS meta) on a third page with the NOINDEX directive as well. We expected the one without the meta tag to at least get indexed along with the homepage of the test site. In addition to those 3 control pages, we had 3 pages where we had an internal search results page with the dynamic NOINDEX header. A listing page with no such header and the homepage with no such header. With Google, the correct indexation occured with only 3 pages being indexed, being the homepage, the listing page and the control page without the metatag. However, with BING, there's nothing. No page indexed at all. Not even the flat static HTML page without any robots directive. I have a valid sitemap.xml file and a robots.txt directive open to all engines across all pages yet, nothing. I used the fetch as Bingbot tool, the SEO analyzer Tool and the Preview Page Tool within Bing Webmaster Tools, and they all show a preview of the requested pages. Including the ones with the dynamic header asking it not to index those pages. I'm stumped. I don't know what to do next to understand if BING can accurately process dynamic headers or AngularJS content. Upon checking BWT, there's definitely been crawl activity since it marked against the XML sitemap as successful and put a 4 next to the number of crawled pages. Still no result when running a site: command though. Google responded perfectly and understood exactly which pages to index and crawl. Anyone else used dynamic headers or AngularJS that might be able to chime in perhaps with running similar tests? Thanks in advance for your assistance....0 -
Existing URL structure and how to handle new pages before migration
Hi there! Currently, our site uses underscores "_" within the url structure. We are moving to Wordpress soon (the site is currently static html) but it will be a couple of months before the migration. Here is an example of the current structure: www.oldsitestructure.com/about_us/success_stories/custom_vinyl_banners When we do change, our url structure will have hyphen's "-" to separate terms, so the preferred new structure will be: www.oldsitestructure.com/about-us/success-stories/custom-vinyl-banners The entire site (with the exception of our Wordpress blog) currently uses the old structure. We have about 10 - 15 pages we will add before our migration, my question is: Should we use the preferred url structure starting NOW or stick with the old one? And set up 301 redirects are part of the migration process? Many thanks!

Question on Breadcrumb and Canonical
Hi SEOmozers, I have another question. =] Thanks in advance. First question: How important is the breadcrumb for SEO? I know that breadcrumb makes better UX because it shows how the visitor landed on this page and the breadcrumb may show up in the search engine. But other than that, how important is it? Second Question: If I have a page that can be found via 2 locations, how should I handle this in regards to breadcrumb? For example, I have page A. You can access page A via Category A and Category B. Therefore, what I did was list Page A under Category A and when someone visit Category B and click on Page A, it will redirect to the page A that was found via Category A. The problem is on page A, the breadcrumb is Home > Category A > Page A. So if someone visit Category B and click on Page A, it redirects and the breadcrumb shows Home > Category A > Page A. What should I do with the breadcrumb for Category B > Page A? Should I create another page A and just use canonical on it? Should I create another page A but do not index it? or leave it as is? 1 Page A, can be access via 2 categories. Please advise. Thank you!

Link Pages/Directory
Hello, What is best practise for dealing with alot of links. I was thinking of breaking them download to alphabet pages i.e. all A on one page etc... BUT should I then make the links clickable on this list OR that they load to a sub company page which has a clickable link to there website.
