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 -
Do we need both an .XML Sitemap and a .aspx sitemap?
Hi Mozers, We recently switched servers and it came to my attention that we have two sitemaps a XML version of the sitemap and a .aspx version of the sitemap. This came to light as the .aspx version of the sitemap is causing the site to come to a screeching halt as it has some complex code and lists over 80,000 products. My question is do we need both versions of the sitemap? My understanding is that the XML version is for Search Engine bots and the .aspx version is for customers. I can't imagine that anyone is using our .aspx version as it is basically a page with 80,000 links and it's buried away on the site, so we were hoping to kill off the .aspx version of the sitemap and keep the .xml version for Search Engine Bots. I wanted to check here first to make sure we did not any negative search engine implications. Any help would be most appreciated. Thanks so much! Patrick

Is placing an H1 tag below a slideshow a bad practice?
Hello All, It is to my understanding that it is a best practice to have a single H1 headline that corresponds to your title tag at the top of your page, above your content for the best On-Site Optimization. We are developing a site that uses a big slideshow with text on each slide, and are concerned that placing the H1 Headline below this will be a bad practice. Would a better option be to have the slide show text on the image and place no alt tags on the slides, so that the crawlers accessing the page overlook this and see the H1 below the slider first? We need to maintain the slider for design purposes, but would like the site to optimized. A similar example to what the slider will look like is as follows: http://www.boviskyle.com/ However, we look to have optimized, "10x" content below the slider with a solid H1 headline as well. Thank You!

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 -

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?
