W3C html5 meta tags invalid?
-
Dear Mozers,
we get errors when validating meta tags in html5.
I know it's experimental and not all metas are valid, but how do you handle this? Leave the tags out?
here are some examples:
`…name="DC.title" content="my content...xyc.." /**>**` ``` `>` ``` `>` ``` `>` ``` `>` `>`
I tried to find some information but couldn't. What would you do? Thanks a lot, Barbara

Thanks a lot Oleg!!

Did some more research... those aren't valid name values - see this.
DC.title = <title>your title here</title>
author =
language =
copyright - no longer valid, just place it into your footer as regular text
reply-to - not sure what this does
cache - must be set via htaccess/server side. and http-equiv is no longer valid
Cheers

Hi Oleg,
thank you for your answer.
Here are the errors:
Bad value DC.title for attribute name on element meta: Keyword dc.title is not registered.
Bad value web_author for attribute name on element meta: Keyword web_author is not registered.
Bad value copyright for attribute name on element meta: Keyword copyright is not registered.
Bad value language for attribute name on element meta: Keyword language is not registered.
Bad value reply-to for attribute name on element meta: Keyword reply-to is not registered.
Bad value pragma for attribute http-equiv on element meta. -
What error is given? Those are still valid HTML5 tags - see this.
Only difference I see is self-close in your code.

Google not detecting hreflang tags
Hey guys, Recently (approx 1 month ago) did a migration from the .co.uk version of our site to .com/en. We've been doing a migration every few months to get everything under our .com. Previous migrations haven't had any problems at all, and hreflang tags detected correctly. For this new UK migration (that was done 1 month ago) google is saying that it doesn't detect any hreflang tags. We place our hreflang tags in our sitemap and so far we haven't had any problems with it. Here's the sitemap: https://camaloon.com/en/web-sitemap.xml Any thoughts on what could be happening? I really appreciate your input and help 🙌

Can OG titles be used as a substitute for Meta titles
We use og (open graph) titles in lieu of meta titles. Is there any downside to using just one. Should we be using both og and meta titles on our page. Appreciate any insight. Himanshu

Rel-canonical and meta data
Hey Mozzers, Help please. I am migrating content for a new website (1000's of pages) and am using the canonical tag on a number of pages. For the pages which I am asking Google not to recognise / index as the master version, and in the interests of time do I need to take the time to fill in the meta <title><description> etc each time?</p> <p>Ben</p></title>

Different meta descriptions for same page
Hi Depending what terms I put into Google I am seeing a different meta description for exactly the same page. I have checked Umbraco CMS and everything seems in working order. Is there a reason this would be happening? Anyone else had trouble like this?

Tags, Categories, & Duplicate Content
Looking for some advice on a duplicate content issue that we're having that definitely isn't unique to us. See, we are allowing all our tag and category pages, as well as our blog pagination be indexed and followed, but Moz is detecting that all as duplicate content, which is obvious since it is the same content that is on our blog posts. We've decided in the past to keep these pages the way they are as it hasn't seemed to hurt us specifically and we hoped it would help our overall ranking. We haven't seen positive or negative signals either way, just the warnings from Moz. We are wondering if we should noindex these pages and if that could cause a positive change, but we're worried it might cause a big negative change as well. Have you confronted this issue? What did you decide and what were the results? Thanks in advance!

Googleoff/on tags
Hi all, I'd like to restrict Google indexing a part of content on the page. Does tag really work for it as it described on https://developers.google.com/search-appliance/documentation/46/admin_crawl/Preparing#pagepart? Thanks, Jane

Using alt-codes such as ? in META title / description
Noticed a search result recently that really caught my eye and certainly stood out among the other 10 results on the page, the META description contained the following snippet: "Learn more about our ★★★★★ rated service..." Any opinions on how using such alt-chars might effect search positioning when used in either the title or description META tags? The starts certainly looked very different to anything else on the page... The claim of 5 star rated service was pretty much accurate so it was genuine and fair to use it...
