      For a websites that differ between catalogs (PDPs) what hreflang error causes the least harm?

      Obviously the best solution is to only have hreflang for shared products, but this takes more work to implement. So when no identical product exists...

      1. Hreflang points to 404 or 410 error.

      2. Hreflang points to 200 status "Page Not Found" page. This obviously has the additional issue of needing to point back to 100+ urls.

      I want to avoid having Google decide to ignore all hreflang due to errors as many correct urls will exist.

      Any thoughts?

        As you wrote in your question, it is best to only link when the product exists in those other countries/languages. Both of the options about which you inquired are problematic, for different reasons. I would say that if you can't adjust the application code to only include hreflang when the pages really exist, then I think you should remove the hreflang tags from the pages, and instead manually create your sitemap with hreflang implemented there. That means your sitemap would not be perpetually up-to-date. But a slightly out-of-date sitemap with correct hreflang tagging would beat either of the options you listed above.

          Getting the Titles and Headings Right on Product Pages. Userbility vs SEO

          Hey Mozzers, I am optimising a chaotic section of the site including many similar products. Writing unique content etc. The titles and urls were all over the place so my first job was to tidy them up so I could make some sense of the situation, especially as sometimes they didn't even match! I should point out were on Magento, so product name = Both the Heading and Title of the page, the meta title can be set separately. When i refer to title I mean both <title>and <h1></strong><br /><br />Before they existed as such<br />URL:  domain.com/200-x-0-5-g-rs-232-balance.html<br />TItle:   PC-1234 200 x 0.5g x 0.3 RS-232 Balance<br /><br />This format was (Product Code, Capacities, Resolutions, Accuracy, Product Title)<br /><br />The issue was all 60 products in a page followed this format. Navigating through the page was a nightmare and was just a jumble of numbers and highly confusing even to me who learnt what they all mean, especially when you had 8 products from the same range you got presented with<br /><br />APC-1234 200 x 0.5g x 0.3 RS-232 Balance<br />APC-1235 500 x 1g x 0.3 RS-232 Balance<br />APC-1236 1000 x 2g x 0.3 RS-232 Balance<br />APC-1238 5000 x 10g x 0.3 RS-232 Balance<br />APC-1239 10000 x 15g x 0.3 RS-232 Balance<br />APC-1210 20000 x 25g x 0.3 RS-232 Balance<br />APC-1211 50000 x 50g x 0.3 RS-232 Balance</p> <p>I changed them to something more user friendly.<br /><br />URL: domain.com/200g-precision-balance.html<br />Title: 200g Precision Balance<br /><br />This has seen the following benefits<br />- URL is now clear and means something to the user<br />- Product titles are easy to navigate and the page is more pleasing to the eye<br />- The jumble of numbers in the title are now all labelled and shown below each product listing in bullet point so the user can see the basic spec of a product without having to decipher any titles<br /><br />Upon reflection I has a couple of concerns I was hoping you could discuss, I am wondering if I have made the titles too simple.<br />1) I have no product code in the title<br />We have our own products manufactured and sell existing brands with their own product codes. Some of these can be lengthy. Adding them makes them hard to the eye and the page looked cramped.<br /><br />The codes are listed beneath each product title on category pages and on a list on the actual product page, but no where in the titles. <br /><br />2)None of our products have a brand listed in the title<br />None of the products on the site had brand names in anything but the images when i started and as such it snuck under my radar. But should i pre-fix all titles with a brand name?<br /><br />Should </p> <p>URL: domain.com/200g-precision-balance.html<br />Title: 200g Precision Balance</p> <p>become</p> <p>URL: domain.com/BRAND1-200g-precision-balance.html<br />Title: BRAND1 200g Precision Balance<br /><br />My instinct tells me to change things to include brands as its useful to the customer and should have an SEO benefit, but to leave out product codes as they are accessible to the customer where they are now and dont make things messy and unreadable.<br /><br />As always, thanks for the input!</p></title>

          Noindex child pages (whose content is included on parent pages)?

          I'm sorry if there have been questions close to this before... I've using WordPress less like a blogging platform and more like a CMS for years now... For content management purposes we organize a lot of content around Parent/Child page (and custom-post-type) relationships; the Child pages are included as tabbed content on the Parent page. Should I be noindexing these child pages, since their content is already on the site, in full, on their Parent pages (ie. duplicate content)? Or does it not matter, since the crawlers may not go to all of the tabbed content? None of the pages have shown up in Moz's "High Priority Issues" as duplicate content but it still seems like I'm making the Parent pages suffer needlessly... Anything obvious I'm not taking into consideration? By the by, this is my first post here @ Moz, which I'm loving; this site and the forums are such a great resource! Anyways, thanks in advance!

          In counting words for a "long article," do comments count in the word count?

          As Moz and others have proven, long articles help ranking, linking and sharing.  My question is, do the comments at the end of an article count in the word count as Google counts it.

          Will "internal 301s" have any effect on page rank or the way in which an SE see's our site interlinking?

          We've been forced (for scalability) to completely restructure our website in terms of setting out a hierarchy. For example - the old structure : country / city / city area Where we had about 3500 nicely interlinked pages for relevant things like taxis, hotels, apartments etc in that city : We needed to change the structure to be : country / region / area / city / cityarea So as patr of the change we put in place lots of 301s for the permanent movement of pages to the new structure and then we tried to actually change the physical on-page links too. Unfortunately we have left a good 600 or 700 links that point to the old pages, but are picked up by the 301 redirect on page, so we're slowly going through them to ensure the links go to the new location directly (not via the 301). So my question is (sorry for long waffle) : Whilst it must surely be "best practice" for all on-page links to go directly to the 'right' page, are we harming our own interlinking and even 'page rank' by being tardy in working through them manually? Thanks for any help anyone can give.

          Does page "depth" matter

          Would it have a negative effect on SEO to have a link from the home page to this page... http://www.website/com/page1deep/page2deep rather than to this page http://www.website/com/page1deep I'm hoping that made some sense. If not I'll try to clarify. Thanks, Mark

          What does the "base href" meta tag do? For SEO and webdesign?

          I have encounter the "base href" on one of my sites.  The tag is on every page and always points to the home URL.

          Would it be bad to change the canonical URL to the most recent page that has duplicate content, or should we just 301 redirect to the new page?

          Is it bad to change the canonical URL in the tag, meaning does it lose it's stats? If we add a new page that may have duplicate content, but we want that page to be indexed over the older pages, should we just change the canonical page or redirect from the original canonical page? Thanks so much! -Amy
