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.

Have Your Thoughts Changed Regarding Canonical Tag Best Practice for Pagination? - Google Ignoring rel= Next/Prev Tagging
Hi there, We have a good-sized eCommerce client that is gearing up for a relaunch. At this point, the staging site follows the previous best practice for pagination (self-referencing canonical tags on each page; rel=next & prev tags referencing the last and next page within the category). Knowing that Google does not support rel=next/prev tags, does that change your thoughts for how to set up canonical tags within a paginated product category? We have some categories that have 500-600 products so creating and canonicalizing to a 'view all' page is not ideal for us. That leaves us with the following options (feel it is worth noting that we are leaving rel=next / prev tags in place): Leave canonical tags as-is, page 2 of the product category will have a canonical tag referencing ?page=2 URL Reference Page 1 of product category on all pages within the category series, page 2 of product category would have canonical tag referencing page 1 (/category/) - this is admittedly what I am leaning toward. Any and all thoughts are appreciated! If this were in relation to an existing website that is not experiencing indexing issues, I wouldn't worry about these. Given we are launching a new site, now is the time to make such a change. Thank you! Joe

How is Single Page Application (SPA) bad for SEO
Hi guys. I am quite inspired of SPA technique. It's really amazing when all your interaction with the site is going on the fly and you don't see any page reloads. I've started implementing the site with this instruction and already found nice guys to make the design. The only downside of the using SPA which I can see **is the **SEO part. That's because the URL does not really change and different pages don't have their unique URL addresses.

Actually they have, but it looks like: yoursite.com/#/products yoursite.com/#/prices yoursite.com/#/contact So all of them goes after # and being just anchors. For Google this mean all of these pages is just yoursite.com/ My question is what is really proven method to implement the URL structure in Single Page Application, so all the pages indexed by Google correctly (sorry I don't mention the other search engines because of market share). The other question, of course, is examples. It will be great to see real life site examples, better authority sites, which use SPA technique and well indexed by search engines.1 -
Is The HREF Link "Title" Tag Needed on Mobile Websites?
Hello To Those Who Are Wiser Than I, I am wondering if the href link "title" tag is needed, or serves any purpose, on mobile websites? Also, does it effect SEO in any way? I ask because generally the href link title tag provides more information to the user when they scroll their mouse over the link - but this action does not happen on mobile! Users have no mouse and thus no extra information would be displayed. I'm really wondering if it still matters for SEO purposes on mobile though. -The UnEnlightened

Incorporating Spanish Page/Site
We bought an exact match domain (in Spanish) to incorporate with regular website for a particular keyword. This is our first attempt at this, and while we do have Spanish speaking staff that will translate/create a nice, quality page, we're not going to redo everything in Spanish page. Any advice on how to implement this? Do I need to create a whole other website in Spanish? Will that be duplicate content if I do? Can I just set it up to show the first page in Spanish, but if they click on anything else it redirects to our site? I'm pretty clueless on this, so if anything I've suggested is off-the-wall or a violation, I'm really just spit-balling, trying to figure out how to implement this. Thanks, Ruben

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

Pages vs. Posts for SEO
Hi, I would like your thoughts about pages vs. posts for SEO. I understand the difference in terms of WP structure and have read the SEOmoz blog post about setting up your site for SEO success (http://www.seomoz.org/blog/setup-wordpress-for-seo-success). However, if you're trying to rank for a particular keyword, it seems that either one could work, from an on-page SEO perspective, as far as title tag, URL, meta description, etc. So how do you decide whether to set up a page vs. a post? What are the pros and cons, from an SEO perspective, about using one vs. the other? Thanks in advance! Carolina

Is it necessary to redirect every Error page (404 or 500) found?
If I have Hundreds of pages with 404 and 500 erros should set up 301 redirects for all of them? Some of the pages have external links, some don't.
