      I came across this article about telling google not to crawl a portion of a webpage, but I never hear anyone in the SEO community talk about them. http://perishablepress.com/press/2009/08/23/tell-google-to-not-index-certain-parts-of-your-page/

      Does anyone use these and find them to be effective? If not, how do you suggest noindexing/canonicalizing a portion of a page to avoid duplicate content that shows up on multiple pages?

        I usually do one of these:

        • put the duplicate content in an iframe (ugly and not flexible). I use this for static content like ad spaces

        • load the content async with Javascript. All googlebot will index is an empty div. The user will see the content loaded with JS after the page loaded. In most cases there is no noticeable difference in how the page renders.Very easy to do with Jquery. My favorite solution.

          Thanks for clarifying!

          Do you have any suggestions on how I can avoid duplicate content that is appearing on multiple pages without noindexing the whole page (there is original content at the top, duplicate at the bottom)?

              Does google look at H3 tags?

              I've had someone tell me that google doesn't pay attention to H3 tags -- only H1 and H2.  I haven't found much online to back this up or discredit it; thought I'd ask the Moz community!

              Hidden H1 Tag on Image

              Hi, In the page I'm working on, I encountered an tag in an image, rather than in a text form. Do you think it's an issue when it comes to SEO?
              What do you suggest I should do if there is an issue? Keen to hear from you!

              SEO advice on ecommerce url structure where categories contain "/c/"

              Hi! We use Hybris as plattform and I would like input on which url to choose. We must keep "/c/" before the actual category. c stands for category. I.e. this current url format will be shortened and cleaned:
              https://www.granngarden.se/Sortiment/Husdjur/Hund/Hundfoder-%26-Hundmat/c/hundfoder To either: a. 
              https://www.granngarden.se/husdjur/hund/hundfoder/c/hundfoder b.
              https://www.granngarden.se/husdjur/hund/c/hundfoder (hundfoder means dogfood) The question is whether we should keep the duplicated category name (hundfoder) before the "/c/" or not. Will there be SEO disadvantages by removing the duplicate "hundfoder" before the "/c/"? I prefer the shorter version ofc, but do not want to jeopardize any SEO rankings or send confusing signals to search engines or customers due to the "/c/" breaking up the url breadcrumb. What do you guys say and prefer from the above alternatives? Thanks /Hampus

              Vanity URLs are being indexed in Google

              We are currently using vanity URLs to track offline marketing, the vanity URL is structured as www.clientdomain.com/publication, this URL then is 302 redirected to the actual URL on the website not a custom landing page. The resulting redirected URL looks like:  www.clientdomain.com/xyzpage?utm_source=print&utm_medium=print&utm_campaign=printcampaign. We have started to notice that some of the vanity URLs are being indexed in Google search. To prevent this from happening should we be using a 301 redirect instead of a 302 and will the Google index ignore the utm parameters in the URL that is being 301 redirect to?  If not, any suggestions on how to handle? Thanks,

              Title Tag vs. H1 / H2

              OK, Title tag, no problem, it's the SEO juice, appears on SERP, etc.  Got it. But I'm reading up on H1 and getting conflicting bits of information ... Only use H1 once? H1 is crucial for SERP Use H1s for subheads Google almost never looks past H2 for relevance So say I've got a blog post with three sections ... do I use H1 three times (or does Google think you're playing them ...) Or do I create a "big" H1 subhead and then use H2s? Or just use all H2s because H1s are scary?  🙂 I frequently use subheads, it would seem weird to me to have one a font size bigger than another, but of course I can adjust that in settings ... Thoughts? Lisa

              <sub>& <sup>tags, any SEO issues?</sup></sub>

              Hi - the content on our corporate website is pretty technical, and we include chemical element codes in the text that users would search on (like S02, C02, etc.) A lot of times our engineers request that we list the codes correctly, with a <sub>on the last number. Question - does adding this code into the keyword affect SEO? The code would look like SO<sub>2</sub>.</sub> Thanks.

              Hreflang Tag great for Google, what about Bing or others?

              I've read that the Hreflang Tag is all the rave for International solutions on a per page basis. I haven't read much about what International agencies are using for non-Google search engines such as Bing. Is the common language meta tags the only solution? would love to see an article that addresses this

              Disallow: /404/ - Best Practice?

              Hello Moz Community, My developer has added this to my robots.txt file: Disallow: /404/ Is this considered good practice in the world of SEO? Would you do it with your clients? I feel he has great development knowledge but isn't too well versed in SEO. Thank you in advanced, Nico.
