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.

Homepage Slider How to Handle H1 and H2's
Working on a site with a slider on the homepage, I dislike them but owner wants to keep in place. Currently, the slider has 4 slides with different images but the same text, so the slider has 4 slides with 4 identical H2 tags and accompanying text. There is no H1 tag on the page at all. It seems to me that a better solution would be to change the first slide to be H1 (with the target keyword) and rework the text in the other slides as H2 tags to appeal to the user. This does mean that the H1 and H2 tags in the slider would be styled the same. Is this a sensible approach?

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

Reason for robots.txt file blocking products on category pages?
Hi I have a website with thosands of products. On the category pages, all the products are linked to with the code “?cgid” in the URL. But “?cgid” is also blocked in the robots.txt file for some reason. So I'm thinking it's stopping all my products getting crawled by Google. Am I right here? Is there any reason why a website would want to limit so many URL's? I'm only here a week and the sites getting great traffic, so don't want to go breaking it!!! Thanks

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!

How to Add canonical tags on .ASPX pages?
What is the proper way (or is it possible) to add canonical tags on website pages that end in .aspx? If you add a canonical tag to the Master Page it will put that exact canonical tag on every page, which is bad. Is there a different version of the tag to put on individual pages? And one to put on the home page without the Master Page error?

Custom URL's with Bigcommerce Issue (Is it worth it?)
We're building out a store in Bigcommerce, who for all intensive purposes is perfect for SEO besides the fact that you can not change the URL's to be custom. My question is, does this kill the SEO value of bigcommerce, despite everything else being great? So for example the URL's for a category page would be something like this www.mysite.com/categories/keyword and the product URL's are pulled in by product name, so product URL's could be something like www.mysite.com/products/Product-Description-Long-223.html (notice the words will be capitalized and their is no way to remove the trailing .html) I could go with Interspire (the liscenced version of Bigcommerce) or Magento so I can custom edit this stuff. But then its a lot more work for my employee's on the buildout.
