SEO audit with Open Graph and picture element support

What is Open Graph?

Open Graph was launched in 2010 by Facebook to offer an easier integration between Facebook and other websites. Major social media platforms now also support Open Graph tags.

The purpose of Open Graph tags is to provide information for social shares. For example, when you share a web page link on Facebook, the Open Graph tags can provide the correct thumbnail image and the correct description for the page.

Open Graph code has no influence on search engine optimization. However, good thumbnail images and descriptions can increase the number of clicks that your shared web pages get on social websites.

Open Graph meta tags are put in the <head> section of a web page. They can look like this:

<meta property="og:title" content="This is an example title" />
<meta property="og:url" content="" />

The website audit tool now checks URLs in these Open Graph tags:

  • og:url
  • og:image
  • og:image:url
  • og:image:secure_url
  • og:video
  • og:video:url
  • og:video:secure_url

Checking the Open Graph tags makes sure that social networks will display your shared pages correctly.

What are picture elements?

The <picture> element was designed for responsive web pages. The <picture> element contains zero or more <source> elements and one <img> element to provide versions of an image for different displays or devices. The browser will consider each child <source> element and choose the best match among them.

If there is no match for the current display, the URL of the <img> element’s src attribute is selected. A picture element can look like this:

<source srcset="/images/large-image.jpg" media="(min-width: 800px)">
<img src="/images/small-image.jpg" />

Web pages load much faster on mobile devices if only small versions of images are loaded. That’s why it makes sense to use the <picture> on your web pages.

The website audit tool makes sure that your images load correctly on all devices (smartphones, tables, notebooks, desktop computers, etc.).

What else does the website audit tool check?

The website audit tool in SEOprofiler checks everything that can influence the position of your web pages on Google and other search engines:

Indexability, HTTP status codes, broken links, titles, duplicate content, spelling mistakes, images, body text, canonical tags, link depth, content topics, redirects, viewport, headlines, nofollow tags, file sizes, robots.txt, structured data, web page performance, and much more.
