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?

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 -
Is it better to redirect a url or set up a landing page for a new site?
Hi, One of our clients has got a new website but is still getting quite a lot of traffic to her old site which has a page authority of 30 on the home page and has about 20 external backlinks. It's on a different hosting package so a different C block but I was wondering if anyone could advise if it would be better to simply redirect this page to the new site or set up a landing page on this domain simply saying "Site has moved, you can now find us here..." sort of idea. Any advice would be much appreciated Thanks

Decreasing Page Load Time with Placeholder Images - Good Idea or Bad Idea?
In an effort to decease our page load time, we are looking at making a change so that all product images on any page past page 1 load with a place holder image. When the user clicks to the next page, it then loads all of the images for that page. Right now, all of the product divs are loaded into a Javascript array and loaded in chunks to the page display div. Product-heavy pages significantly increase load time as the browser loads all of the images from the product HTML before the Javascript can rewrite the display div with page-specific product HTML. In order to get around this, we are looking at loading the product HTML with a small placeholder image and then substituting the appropriate product image URLs when each page is output to the display div. From a user experience, this change will be seamless and they won't be able to tell the difference, plus they will benefit from a potentially a short wait on loading the images for the page in question. However, the source of the page will have all of the product images in a given category page all having the same image. How much of a negative impact will this have on SEO?

Missing Meta Description Tag - Wordpress Tag
I am going through my crawl diagonostics issues and I have lots of "Missing Meta Description Tags". However when I look at the url's they are Wordpress Tags, which do not have a meta description. Shall I just ignore these errors or should I find a way to add a meta description? Is it important?

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.

How do search engines interpret <hgroup>...</hgroup> tags?
Hi there. I'm building an HTML 5 site and through research of new HTML 5 elements I've seen little conclusive information about the interpretation of the new <hgroup>tag, in terms of SEO application and interpretation. In particular does Google interpret the nested heading tags as individual elements or does it combine them into one entity? For example, say I have: <hgroup> # Article Heading ## Article Sub-heading </hgroup> How is this interpreted by Google and what would be some good SEO best practices regarding the <hgroup>tag in HTML5: Is it interpretted as a single tag (" Article Heading: Article Sub-heading ") or two separate heading tags (one and one )? Also, how much does the ordering of the tags matter (say for example I wanted something like the following for visual purposes? <hgroup> ## Article Sub-heading # Article Heading </hgroup> One last thing: is it safe to assume that it is indeed OK to have multiple tags on a single page (as referenced by Matt Cutts a while back in a Webmaster Video)? Thanks! </hgroup> </hgroup>
