What's wrong with my structure data?

Question

It's been more than 4 months that our rich snippets suddenly disappeared, some error were reported in GWT, i corrected everything and errors are now decreasing (only 5 left). here is my code:

<section class="c-center" itemscope itemtype="http://schema.org/Product">
    <div>
        <h1><span itemprop="name">Product name</span> <span itemprop="brand" class="brand"><a href="/link-to-brand/">Brand of product</a></span></h1>
        <div id="reviews" itemprop="aggregateRating" itemscope itemtype="http://schema.org/AggregateRating">
            <div class="rating">
                <meta itemprop="ratingValue" content="4.8" />
                <meta itemprop="ratingCount" content="56" />
                <div class="fill" style="width:96%"></div>
                <div class="stars"></div>
            </div>
            <div class="rating-info">
                <a href="#ratings-reviews">Based on 56 reviews</a> - <a href="#">Write a review</a>
            </div>
        </div>
    </div>

    <div id="img">
        <img src="/link-to-image.jpg" alt="Img alt" itemprop="image" />
    </div>

    <div id="info">
        <meta itemprop="url" content="site.com/link-of-product/">
        <div id="price-container" itemprop="offers" itemscope itemtype="http://schema.org/Offer">
            <meta itemprop="priceCurrency" content="EUR">
            <meta itemprop="gtin13" content="1234567899999">
            <span class="price" itemprop="price">19,95 €</span> <del>28,50 €</del> -
            <span class="stock"><link itemprop="availability" href="http://schema.org/InStock">Available</span>
        </div>
    </div>
</section>

here are my questions:
1- is there anything wrong?
2- I've seen in many posts that currency should not be in the itemprop="price" but in google examples, they do include it! what should I do?
3- should I use ratingCount or reviewCount ?
4- some products exist in different sizes with different prices, is it recommended to include the AggregateOffer with lowest and highest price?

Thanks a lot

Answer 1

How does it appear visually?

The structured data linter shows a typical snippet which looks good and has star rating, and there are no errors in google's tool. Two things which stand out are:

• url has no protocol, set to http://yoursite.com/page1 for
• price should be number only, which could well be affecting search results, currency is a separate field so should not be embedded in price as well
• use <meta> to give your price with a full stop as the separator, not the comma and put large values as 1234567.89 not 1,234,567.89 or 1.234.567,89 but display it as you would normally

price info from http://schema.org/

Use the priceCurrency property (with ISO 4217 codes e.g. "USD") instead of including ambiguous symbols such as '$' in the value.

Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.

Note that both RDFa and Microdata syntax allow the use of a "content=" attribute for publishing simple machine-readable values alongside more human-friendly formatting.

Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similiar Unicode symbols.

google actually gives this example in its policies page

<span itemprop="priceCurrency" content="USD">$</span><span itemprop="price">119.99</</span>

• previous Offer price, you could include in <del> structured data for the expired Offer price, with priceValidUntil set to a date in the past, the current price can also have an expiry date.

• consider setting itemCondition to http://schema.org/NewCondition

• image urls - I've noticed that full url starting path rather than a relative path seem to be preferred - your /link-to-image.jpg is interpreted as http://example.com/link-to-image.jpg not http://site. com/link-to-image.jpg in the testing tool, I'm unsure if this is the same when testing direct from the URL but it seems best not to be amigous

• lastly use a shopping search tool, including google shopping to search for a best seller, see if it can find it by price, brand, availability etc. if competitor sites appear first you can even check the structured data tester with their URL to see if you are missing anything
