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.

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 -
Multiple Local Schemas Per Page
I am working on a mid size restaurant groups site. The new site (in development) has a drop down of each of the locations. When you hover over a location in the drop down it shows the businesses info (NAP). Each of the location in the Nav list are using schema.org markup. I think this would be confusing for search robots. Every page has 15 address schemas and individual restaurants pages NAP is at the below all the locations' schema/NAP in the DOM. Have any of you dealt with multiple schemas per page or similar structure?

ECWID How to fix Duplicate page content and external link issue
I am working on a site that has a HUGE number of duplicate pages due to ECWID ecommerce platform. The site is built with Joomla! How can I rectify this situation? The pages also show up as "external " links on crawls... Is it the ECWID platform? I have never worked on a site that uses this. Here is an example of a page with the issue (there are 6280 issues) URL: http://www.metroboltmi.com/shop-spare-parts?Itemid=218&option=com_rokecwid&view=ecwid&ecwid_category_id=3560081

Do pull quotes affect SEO positively or negatively?
I like the design element of a pull quote to ad interest and highlight an important point. If I use an exact quote from the page in a pull quote on that page, does that negatively affect SEO as duplicate content? Are there formatting or tagging methods that could help pull quotes to boost SEO? For clarity, by "pull quote" I mean a stylized bit of text that floats on a page in such a way that the body text wraps around it. It is actual text (not text embedded in a graphic) but it behaves like an image with text wrapping around it. Here's an example (in red on the right side): http://www.21ct.com/resources/news-room/21ct-announces-its-latest-us-patent-for-advancing-big-data-security/

Duplicate H1 tag IF it holds SAME text?
Hello people, I know that majority of SEO gurus (?) claim that H1 tag should only be used once per page. In the landing page design I'm working with, we actually need to repeat our core message stated in H1 & H2 - at the bottom of the page. Now the question is: Can that in any way cause any ranking penalty from big G? In my eyes that is not attempt to over optimize page as it contains SAME info as the H1 & H2 at the top of the page. Confusing, so I'm hope that some SEO gurus here will share some light on this. Thanks in advance!

What else should you call the Home page?
In the menu bar and footer the main page is called Home. Would it confuse people to rename it to Business Name Home or Business Name? How do you handle this?

Indexing Dynamic Pages
Hi, I am having an issues among others, regarding indexing dynamic pages. Our website, www.me-by-melia, was just put live and I am concerned the bottom naviagtion pages (http://www.me-by-melia.com/#store, http://www.me-by-melia.com/#facebook, etc) will not be indexed and create duplicate pages. Also, when you open these pages in a new tab, it takes you to homepage. The website was created in HTML5. Please advise.

Footer backlinks for sites I've developed
I link back to my website via my company name on the footers of sites I develop. Lately I've been changing this to my keyword and mixing and matching. This has been done for new sites I create and old sites I've not seen any benefit so far after a couple of months. Most my clients are hosted on the same server as my main site that it links back to. 1. Is this a bad idea to link back on the same IP?

2. Is footer backlinks to the main developer going to annoy Google?
3. Should I change my main site's server, will it help? All my competitors seem to do it and as far as I can tell they seem to get better results than I do. Because I'm now changing them the reason I see no benefit? Thanks0
