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.

Problems preventing Wordpress attachment pages from being indexed and from being seen as duplicate content.
Hi According to a Moz Crawl, it looks like the Wordpress attachment pages from all image uploads are being indexed and seen as duplicate content..or..is it the Yoast sitemap causing it? I see 2 options in SEO Yoast: Redirect attachment URLs to parent post URL. Media...Meta Robots: noindex, follow I set it to (1) initially which didn't resolve the problem. Then I set it to option (2) so that all images won't be indexed but search engines would still associate those images with their relevant posts and pages. However, I understand what both of these options (1) and (2) mean, but because I chose option 2, will that mean all of the images on the website won't stand a chance of being indexed in search engines and Google Images etc? As far as duplicate content goes, search engines can get confused and there are 2 ways for search engines

to reach the correct page content destination. But when eg Google makes the wrong choice a portion of traffic drops off (is lost hence errors) which then leaves the searcher frustrated, and this affects the seo and ranking of the site which worsens with time. My goal here is - I would like all of the web images to be indexed by Google, and for all of the image attachment pages to not be indexed at all (Moz shows the image attachment pages as duplicates and the referring site causing this is the sitemap url which Yoast creates) ; that sitemap url has been submitted to the search engines already and I will resubmit once I can resolve the attachment pages issues.. Please can you advise. Thanks.0 -
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 -

What seo benefit does setting up a photo gallery where each photo is a separate web page?
what seo benefit does setting up a photo gallery where each photo is a separate web page? My old SEO guy set up my photo gallery like that claiming that because each photo was a separate page, it added a big seo benefit and i never understood what he was talking about. Maybe alt text on the photo with key phrases in it pointing to my other pages to give my site a theme for google? I'm not really sure. He has since moved away and i am considering redoing the photo gallery to multiple images on one page to be more user friendly to my users. This photo gallery is 3 years old and the photos might have some page rank to them helping my site so i don't want to remove this gallery if there really is a benefit to it and it will hurt my site. I once removed four static page rank 3 pages from my site that weren't used for my site anymore and my rankings dropped 5 positions. Thoughts anyone? Thanks! Ron

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/

Flat vs. Silo Site Architecture, What's Better
I'm in the midst of converting a fairly large website (500+ pages) into WordPress as a content management system. I know that there are two schools of thought regarding site architecture: Those who believe that everything should be categorized, I.E.- website.com/shoes/reebok/running People who believe that the less clicks it takes from the homepage the better. As it stands, our current site has a completely flat architecture, with landing pages being added randomly to the root, I.E.- website.com/affordable-shoes-in-louisville-ky I'm beginning to think that there is a gray area with this. I spoke to someone who says that you should never have a page more than 2 categories/subfolders deep. But if we plan on adding a lot of content doesn't it make sense to set the site up into many categories so we can set a good foundation for adding massive amounts of content. Also, will 301 redirecting to the new structure cause us to lose rankings for certain terms? Any help here is appreciated.

Site-wide footer links or single "website credits" page?
I see that you have already answered this question before back in 2007 (http://www.seomoz.org/qa/view/2163), but wanted to ask your current opinion on the same question: Should I add a site-wide footer link to my client websites pointing to my website, or should I create a "website credits" page on my clients site, add this to the footer and then link from within this page out to my website?
