Two different canonical tags on one page
-
Due to an error, some of my pages now have two canonical tags on them. One is correct and the other goes to a nonsense URL (404 page).
I know I should ideally remove the incorrect ones, but it's a big manual job. Are they doing any harm? Can I just leave them there and let Google figure it out?
The correct ones are higher up in the code. Will this make a difference?
Any help appreciated.

Unfortunately, what Google can do and what they actually do can really vary. If you're mixing signals and doubling up the canonicals, the odds that they'll get it right are pretty low, in my experience. I think it's worth the fix, if these are traffic-generating pages.

You should certainly fix this. You don't want google having to guess what you are trying to tell them. For the most part they will probably get it right, especially in your case with the 404s. But if this is occurring too frequently then they may begin to ignore your canonicals all together. Or worse, you may loose some google trust.
I'd put this on my fix it list.

Thanks Scott. It's only wrong on a few hundred pages and they're all quite deep. If it were wrong on the important pages I'd fix it.

You should change it, I'm no canonical expert, but the whole point of having it is to tell google how you want it to show, ex. www.yoursite.com or yoursite.com. If your not going to change it for all of your pages then at least do it for your home page as this is the one that usually gets the most attention.
-
Well that's good news. Think I'll just leave them there then. Thanks!

This is stright from Google Webmasters:
"What happens if rel="canonical" points to a non-existent page? Or if more than one page in a set is specified as the canonical version?
We'll do our best to algorithmically determine an appropriate canonical page, just as we've done in the past."

Two websites, one company, one physical address - how to make the best of it in terms of local visibility?
Hello! I have one company which will be operating in two markets, printing and website design / development. I’m planning on building two websites, each for every market. But I’m a bit confused about how to optimize these websites locally. My thought is to use my physical address for one website (build citations, get listed in directories, etc. ) and PO Box for another. Do you think there is a better idea?

Removing a canonical tag from Pagination pages
Hello, Currently on our site we have the rel=prev/next markup for pagination along with a self pointing canonical via the Yoast Plugin. However, on page 2 of our paginated series, (there's only 2 pages currently), the canonical points to page one, rather than page 2. My understanding is that if you use a canonical on paginated pages it should point to a viewall page as opposed to page one. I also believe that you don't need to use both a canonical and the rel=prev/next markup, one or the other will do. As we use the markup I wanted to get rid of the canonical, would this be correct? For those who use the Yoast Plugin have you managed to get that to work? Thanks!

Home Page Ranking Instead of Service Pages
Hi everyone! I've noticed that many of our clients have pages addressing specific queries related to specific services on their websites, but that the Home Page is increasingly showing as the "ranking" page. For example, a plastic surgeon we work with has a page specifically talking about his breast augmentation procedure for Miami, FL but instead of THAT page showing in the search results, Google is using his home page. Noticing this across the board. Any insights? Should we still be optimizing these specific service pages? Should I be spending time trying to make sure Google ranks the page specifically addressing that query because it SHOULD perform better? Thanks for the help. Confused SEO :/, Ricky Shockley

Product Pages Outranking Category Pages
Hi, We are noticing an issue where some product pages are outranking our relevant category pages for certain keywords. For a made up example, a "heavy duty widgets" product page might rank for the keyword phrase Heavy Duty Widgets, instead of our Heavy Duty Widgets category page appearing in the SERPs. We've noticed this happening primarily in cases where the name of the product page contains an at least partial match for the desired keyword phrase we want the category page to rank for. However, we've also found isolated cases where the specified keyword points to a completely irrelevent pages instead of the relevant category page. Has anyone encountered a similar issue before, or have any ideas as to what may cause this to happen? Let me know if more clarification of the question is needed. Thanks!

Isnt it better to have headlines in H1 and H2 tags instead of p tags?
I am working with a simple site http://http://lightsigns.com/Uniko_Manufacturing_Limited.html They seek more SEO traffic. However, the two big headlines that read "Wholesale Supply to the Sign and Display Industries" which is on line 241 and 242 of the source code, its in a p tag, i.e. <p <span class="webkit-html-tag">style</p <span>="padding-top: 0pt; " class="paragraph_style_1">Wholesale Supply to the and <p <span class="webkit-html-tag">style</p <span>="padding-bottom: 0pt; " class="paragraph_style_1">Sign and Display Industries Likewise, the product titles are in p tags, also. For example, on the Slide-in Light Box product page, http://lightsigns.com/Slide_In_light_box.html , I have done keyword research and no one is using the words slide in light box.Plus, it is also a p tag, ie. line 43 reads style="padding-bottom: 0pt; padding-top: 0pt; " class="paragraph_style">Slide-in Light Box If I suggest that they make an H2 tag with SEO-optimized keywords such as Display Light Box - Slide-In LIght Box, would this indeed help SEO? In summary, is it correct to say that H1 and H2 tags are stronger signals to the search bots of what the page is about?

Handling 301s: Multiple pages to a single page (consolidation)
Been scouring the interwebs and haven't found much information on redirecting two serparate pages to a single new page. Here is what it boils down to: Let's say a website has two pages, both with good page authority of products that are becoming fazed out. The products, Widget A and Widget B, are still popular search terms, but they are being combined into ONE product, Widget C. While Widget A and Widget B STILL have plenty to do with Widget C, Widget C is now the new page, the main focus page, and the page you want everyone to see and Google to recognize. Now, do I 301 Widget A and Widget B pages to Widget C, ALTHOUGH Widgets A and B previously had nothing to do with one another? (Remember, we want to try and keep some of that authority the two page have had.) OR do we keep Widget A and Widget B pages "alive", take them off the main navigation, and then put a "disclaimer" on the pages announcing they are now part of Widget C and link to Widget C? OR Should Widgets A and B page be canonicalized to Widget C? Again, keep in mind, widgets A and B previously were not similar, but NOW they are and result in Widget C. (If you are confused, we can provide a REAL work example of what we are talkinga about, but decided to not be specific to our industry for this.) Appreciate any and all thoughts on this.

URL query strings and canonical tag
Hi, I have recently been getting my comparison website redesigned and developed onto wordpress and the site is now 90% complete. Part of the redesign has meant that there are now dynamic urls in the format: http://www.mywebsite.com/10-pounds-productss/?display=cost&value=10 I have other pages similar to this but with different content for the different price ranges and these are linked to from the menus: http://www.mywebsite.com/20-pounds-products/?display=cost&value=20 Now my questions are: 1. I am using Joost's All-in-one SEO plugin and this adds a canonical tag to the page that is pointing to http://www.mywebsite.com/10-pounds-products/ which is the permalink. Is this OK as it is or should i change this to http://www.mywebsite.com/10-pounds-products/?display=cost&value=10 2. Which URL will get indexed, what gets shown as the display URL in the SERPs and what page will users land on? I'm a bit confused so apologies if these seem like silly questions. Thanks

What's the difference between a category page and a content page
Hello, Little confused on this matter. From a website architectural and content stand point, what is the difference between a category page and a content page? So lets say I was going to build a website around tea. My home page would be about tea. My category pages would be: White Tea, Black Tea, Oolong Team and British Tea correct? ( I Would write content for each of these topics on their respective category pages correct?) Then suppose I wrote articles on organic white tea, white tea recipes, how to brew white team etc...( Are these content pages?) Do I think link FROM my category page ( White Tea) to my ( Content pages ie; Organic White Tea, white tea receipes etc) or do I link from my content page to my category page? I hope this makes sense. Thanks, Bill
