How Does Facebook Select the Caption and Images?

Well, whenever you or the visitors or users of your website share the blog posts of your website to Facebook. Therefore it generates a preview of that blog post or content, which usually shows an image and caption. However, you can see it in the Facebook preview too.

Basically it shows the pages or blog post that was shared from your website to a Facebook page by a third party application. Although Facebook previews have the Image, Caption, and Introduction. However, the introduction is the message someone writes when sharing the post.

Basically the caption and image are determined by the crawler of Facebook. Therefore the crawler scrapes the HTML of your web pages. After that, it selects the image and caption it uses when the post is shared with Facebook.

Although Facebook has stored the information in its own cache for 30 days after it scraped any of the web pages from your website. Therefore if the other person shares the same post on Facebook. Then the system does not recrawl the web page of your website. But, it just re-publishes the same image and caption which was used last time.

However, a few things may go wrong due to this scraping process. Because Facebook crawlers may grab an image that can be different from the main header image that you have chosen for that post you want to share. Therefore whenever you update the blog post with fresh images or headlines.

Then also the Facebook preview may display the old version of information instead of your new one. Because your Open Graph tags such as og tags did not set up in the correct manner. Therefore as a result the wrong image and caption can show up in the preview.

Although that is where the Facebook debugger comes in. Because the testing of the web pages of your site with the help of Facebook Debugger is very simple such as just entering the address of the web page into its search bar, and then it reviewing the report that it generates.

How Facebook display WordPress Images and Links?

When you share a post on Facebook, so it chooses a specific set of information that defines, what to display. For doing the same the Facebook uses elements called ‘open graph meta tags’ that are also known as ‘og tags’.

Facebook caches your images on their Server and CDN while you share the content on your WordPress site. You can think in the same manner as caching works on your site. Sometimes you need to clear the cache to get something working again.

The same things apply for Facebook – means to say, when sometimes you update something on your site and share it on Facebook, so it may still display an old image. This is because instead of fetching the new information it serves up the already cached information.

Likewise, the same things apply for information about your content and link. They fetch what they call Open Graph Meta Tags.

In accordance with Facebook, the Open Graph protocol allows web pages to become a rich object in a social graph. Generally, these are the tags developed by Facebook in 2010 that inform facebook what information you shared.

Further, the most popular plugin such as Yoast SEO and Social Warfare use “Open Graph Meta Tags” automatically.

For example, visit our guide How to install WordPress. Here you will see the mentioned data regarding the open graph. However, the open graph uses various attributes like og:image, og:locale, etc. This is the code that Facebook uses to display the title, description, and featured image;

<meta property=”og:locale” content=”en_US” />


<meta property=”og:type” content=”article” />

<meta property=”og:title” content=”A complete guide on WordPress Rich Snippet” />

<meta property=”og:description” content=”Basically, a normal Snippet is a result which Google shows to the users in the Search Engine Result Pages. For example, if you are searching for a good recipe for homemade chocolate and you googled it. Google shows you the results list in SERP (Search Engine Result Pages) with normal and rich snippets.” />

<meta property=”og:url” content=”” /><meta property=”og:site_name” content=”wpglobalsupport” />

<meta property=”article:publisher” content=”” />

<meta property=”article:section” content=”Social Media Marketing” />

<meta property=”article:published_time” content=”2018-04-23T11:00:38+03:00″ />

<meta property=”article:modified_time” content=”2018-04-24T11:30:51+03:00″ /><meta property=”og:updated_time” content=”2018-04-24T11:30:51+03:00″ />

<meta property=”og:image” content=”” /><meta property=”og:image:secure_url” content=”” />

<meta property=”og:image:width” content=”695″ /><meta property=”og:image:height” content=”308″ />

Causes of the problem

#1: Well, there are several reasons for this issue. Hence, it is a bit difficult to know which one creating a specific issue. But, most of the time this error occurs due to the inappropriate use of og tags (Open Graph tags set as og: images). Due to this og:image tag error the featured image is smaller than the others.

While you sharing an article on Facebook, so by using og tags it tries to determine which thumbnail is best to use. And sometimes pick a larger image instead of the one you have set. However, sometimes the og tags are missing due to cache plugin or hosting such as CDN systems not choose the right image.

#2: It can also be due to using an image size that Facebook doesn’t like. Further, Facebook accepts at least 200 x 200 px images and prefers at least 600 x 315 px larger images. However, a 1200 x 630 px resolution image is ideal for large displays.

#3. You know very clearly speed up WordPress plays a very important role to rank a site. This means to say, if your pages loading speed is good, then users can focus on your content, otherwise, you can lose your user’s potential.

Fast forward, a WordPress website is only a combination of code and files that run together to create a good interface. But when any user visits your site, so these files and codes need much of processing power from your server – that’s it too much slow. And when you add content to your site it only gets worse.

The reason for the problem is – your server cache a web page. Now the question is how to cache a web page? let’s see – Generally, it creates a  static HTML copy of this and sends it to the browsers of any new visitors.

In reality, you have to clear the cache of your web page when it has changed, many times some small issues occur such as meta title or featured image. Because of this, Facebook unable to upload the correct element.

The best solution to the same problem is using a WordPress caching plugin – we have mentioned below some of the best plugins to clear the cache.

#4. Facebook Caching: Similar to the WordPress site, Facebook also has its own caching system.

When you shared a post to Facebook and you want to tweak your featured image. Therefore, you delete the old one to update and save the new image. And when you uploaded the new one so sometimes Facebook shows your cache.

#5. WordPress has a dedicated widget to set a featured image. But sometimes users forget to set it. In this situation, Facebook behaves the same as the undersized image. It picks the first one properly sized image of your post and shows on the page.

Fast forward, there are two ways to solve the problem;

  1. Manually uploading the images. But there is a problem with this solution – When we click on the image, the image opens in a lightbox instead of moving the reader to the article. And stored in your uploaded images and timeline. This is not a good solution because a user that shares your article will see and share the wrong image.
  2. Using Facebook Sharing Debugger. It is the best solution to fix the problem. However, here we are focusing only on images but the Facebook debugger will also check URLs, titles, descriptions, and much more.

Facebook Caches The Information of Open Graph Meta Tag

Although there is also some other concern viewpoint about How the Facebook preview cards work? However, when it scrapes your website’s HTML. Then the content is cached on Facebook’s servers. Therefore when anyone else tries to shares that same link next time on Facebook. Therefore Facebook will use its own cache information about that.

Rather than doing the same thing again and scraping your website. Because it is very easy to pull that information again and again from its own cache. However, it is very essential because simply it implies that any changes that you made to your websites Open Graph meta tags. They will not update until the Facebook clears its own cache.

Certainly, the Facebook scrapes each link every 30 days by default (source). However, it creates two possible problems. Such as if there are some known issues with the Open Graph meta tags within your content. Also, if you are not using any type of plugin that adds Open Graph meta tags.

Therfore when someone shares your link on Facebook, then you will see some of the wrong titles or image. Although you may not see able to the right images on Facebook, even when you fix all those issues right away. Because the reason behind this is that Facebook cached the older version of your Open Graph tags.

However, the facebook debugger can help you to fix all those problems very easily. First of all, it will help you to find the specific issues with the implementation of your website’s Open Graph meta tags. So that you can make sure that it displayed the proper information and image, when someone shares your website on Facebook.

#2 Step: Clear the WordPress Cache

To get the latest information, you need to ensure the facebook grabs. Before that – clear the entire cache from your site: developed on either of the CMS (Content Management System.)

Caching plugins are fabulously popular! Because they allow the users to increase the performance of their site by storing some content in the visitor’s browsers. But there is a problem – instead of the most up-to-date version, sometimes Facebook can try to drag the og tags from the cached content.

Tips and Tricks For Facebook Image Issues Debugging

Although you can make sure that your WordPress website’s content will always shown perfectly, just by using the Open Graph meta tags and Facebook Debugger when your blog post images are shared on Facebook.

However, you must remember that sometimes the caching can play tricks with that what shows up on the screen. Therefore if you do not see the proper information.

Then you have to make sure that you have clear the cache on your WordPress website. After that, you should force Facebook to scrape it again with Facebook Debugger.

However, there are some extra steps for optimizations that you have to take or complete if you want to ensure that Facebook is able to display the previews of images properly every single time.

Must Use Proper Image Sizes For Facebook

Although it is recommended from Facebook that you must keep the size of the images at least 1200 x 630 pixels that you want to use to maximize the quality of the high-resolution displays. But for the minimum resolution, your images must be at least 600 x 315 pixels.

However, you have to maintain this same aspect ratio of the images even if you want to use some different image sizes. Because if you use a different aspect radio other then the standard one then facebook will crop your images automatically. Therefore if your image ratio is below then the 600 x 315 pixels. Then you will not get the full image preview.

However, you can see what the preview will look like for smaller images on it. Besides that, if the size your image is below then the 200 x 200 pixels. Then you will not be able to get any preview image. In addition, you will see an error message about this on Facebook Debugger.

Fix No Preview Image Issue With Pre-Cache Content

Although if you want to fix no preview image Issue, then you can do so with the help of Pre-Cache Content for any brand new post or pages. Because when anyone shares any one of your links on Facebook for the very first time. Then Facebook may not display any preview image right away.

However, the reason behind that is the crawler of Facebook need to see that image at least once before it can be rendered. In other words, you can understand it as that the first very person who is sharing the piece of content, he will not be able to a rendered image. Although there are two useful ways for that you can fix this.

At the first option, you should run all of your new pages and blog posts through the Facebook debugger just after you publish them on your website. Because this process will allow Facebook to pre-cache the image of your post. So that it can make sure that it shows up right away. Even if the first person share that post for the first time.

On the second option, you can add the og:image:height and og:image:width to the Open Graph meta tags. Therefore this process can allow the crawler to render the post image immediately without having the asynchronously download and process it.
