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!

Short answer; I think you can get more value from an H1 tag, so its a small SEO issue.
However, it really depends what image you're talking about. Is this just a logo? If so it doesn't adequately describe page content in a way that people or search engines can understand. Regardless, putting that image in an H1 tag does nothing for the image.
H tags should display a hierarchy. As James mentions above, H1 tags should contain an editorial description of the page; a headline, this is best for usability (which trickles down to SEO impact).
Anecdotally I've found keywords in H1 tags to have greater sway over page relevance than keywords in body copy. They are certainly one of the areas I pay more attention to. Despite that, it's not unusual to find logos in H1 tags, especially on homepages. But I'd encourage you to consider putting that H1 tag around a keyword optimised mission statement/heading on your homepage instead. The logo can remain visually as prominent. Ranking for your companies name is rarely hard so why have the code focus on that?
What about standards? Well interstingly w3c uses img in an H1 tag. With an alt tag of "w3c". That will be machine readable, but not very helpful as a page heading. Then again w3c goes on to use h1 tag for its page titles as well thus committing the sin of multiple H1 tags. Only thing of relevance they say is that you can include HTML in an H1 tag, so one option is an image and text.
In summary;
- one H1 tag per page
- the right place in the hierarchy (with h2 etc)
- keyword optimised but not spammy/stuffy (for deeper pages consider long tail kewords)
- Short, descriptive and engaging text*
*for example mission statements should say who the website represents, what they do and why they're special. Ideally in less than 20 words; think snappy newspaper headline. Answer user intent!

It's an issue in that it's not correct.
A "header tag" is always text based. They are used to determine, to search engines, what a page is about. The search engines can't really "see" images in the traditional sense so this application is incorrect.
A lot of designers mistakenly wrap the logo in a H1 tag and call it a day. I call it out in audits all the time. It's just not correct or the best practice. It will have no effect for SEO or for image optimization in that format.
Your goal is always to communicate to users (and Google) what the page is about. The proper application of H1 tags is part of that process.

Size of image for article Schema
Hi, I implemented schema markup for an article and all tested fine and I can see it being fired in preview mode of Google Tag Manager. But when I run the URL which has it applied through Google Structured Testing tool it is not appearing. I have now read that the image needs to be a certain size. For AMP articles this appears to be 12oo pixels wide http://www.thesempost.com/google-changes-image-size-requirements-amp-articles/ But what about non-AMP articles? Does it need to be that big too?

Canonical Tag when using Ajax and PhantomJS
Hello, We have a site that is built using an AJAX application. We include the meta fragment tag in order to get a rendered page from PhantomJS. The URL that is rendered to google from PhantomJS then is www.oursite.com/?escaped_fragment= In the SERP google of course doesnt include the hashtag in the URL. So my question, with this setup, do i still need a canonical tag and if i do, would the canonical tag be the escaped fragment URL or the regular URL? Much Appreciated!

Duplicate Title Tag issue due to Shopify CMS
Hi guys, I'm a novice really when it comes to SEO, yet have taken it in house for the next year or so, firstly because I have had my fingers burnt twice...and secondly, to allow me to recoup some of the loss from my prior campaigns. One thing I have noticed on my site (which uses a Shopify E-commerce CMS), is that Shopify duplicates a url for each my products. An example of this is http://www.vidahomes.co.uk/collections/designer-radiators-heating/products/reina-aliano

http://www.vidahomes.co.uk/products/reina-aliano Both products provide exactly the same information, yet appear in different ways subject to how the customer finds them. I contacted Shopify to find a fix to this issue when I noticed a high amount of Duplicate Title Tags in my SEO crawl. Their response was as follows. Using a rel canonical link will help prevent duplicate content issues with search engines. All you need to do is add this line of code: **<link rel="canonical" href="{{ canonical_url }}" />** ** before the tag in the theme.liquid file. It’s that simple :)** The theme liquid file basically generates the outer template for the whole site, and is only compromised when over-ruled. This all seems a little too easy for me, so I am hoping whether someone can elaborate as to whether this will work or not, as I'm not entirely sold on their response. I was always under the impression with canonical tags, that they should be added to the header section of the duplicate page in question, which refers back to the original page. The code I have been told to add above implies that the canonical tag would be added to every page in my site so the Google robot would have a hard time in finding anything at all of relevance Thanks in advance for any assistance with this.

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.

Do the search engines penalise you for images being WATERMARKED?
Our site contains a library of thousands of images which we are thinking of watermarking. Does anyone know if Google penalise sites for this or is it best practice in order to protect revenues? As watermarking these images makes them less shareable (but protects revenues) i was thinking Google might then penalise us - which might affect traffic Any ideas?
