“How to deal with misrepresentative images when sharing Facebook post.”
If you share Facebook posts on various platforms such as T-Story, WordPress, Naver Blog, and sites, you will include a brief title along with your representative image. However, if you share it on Facebook and modify it and share it again, the representative image will not be modified. This is already saved when sharing at first, so you have to tell them that you have modified this part.
This is not a modification on your site, but a shared debugger on Facebook through tools, and I also felt it was difficult, so most of you will share it as it is. If you look at the explanation below, it’s not that difficult, so please try it step by step.
1. Check the image of the representative of the open graph
There’s something you need to check first. If you do not set up an open graph, the image in the post will be set as the representative image. You usually want this. But if the image of the representative of the site is set, all the images of the representative of the shared site will be displayed as the representative image of the site, so you have to check this part.
The way to find out what the open graph is is is to check the HTML section of your site, which is well explained is convenient to check the contents of the Naver HTML markup guide.
When registering webmaster tools, you can set up an open graph, so you can add meta-tags to set up a representative image of the site. If you share a Facebook post, it will all come out as a representative image of the site, so you have to think carefully about adding this meta-tags.
※ The meta tag for the site’s representative image setting is = Meta property = “og:image” content=”.”
2. Setting up a blog representative image
First of all, for those who don’t know how to set up a representative image, if you look at Naver blog in the library on the left, you can see the image you’ve uploaded so far. If you choose here, you can choose a representative image.
Basically, the first image uploaded is set as the representative image, so please check what you wrote through T-Story, Naver Blog, and WordPress when you share your Facebook posts.
3. Go to Developer Center
I shared a Facebook post, but I changed the image because I chose the wrong representative image, but if it doesn’t change, if you look on the right side of my Facebook PC, you can see <More>. You can enter <Developer> from here. You can enter the developer page and enter the tool from the menu. If you’re having a hard time finding it, you can click on the one on the bottom to move on.
4. Request as a Shared Debugger
When you enter the developer tool, you will see a shared debugger in the middle. If you look at the description, you’ll be able to preview how the content is shared on Facebook. It says, “You can see a preview here and debug problems with open graph tags.
※ Debug : The debugger refers to the process of finding an error in a program and identifying the cause of the error.
When you enter the shared debugger, a window appears that enters the URL of the post you want to share. After you enter here, press the debug button on the right, and you can modify it with the details. I sometimes make a mistake of entering the address of a Facebook post here, but I did. If it is exactly a blog post, you must enter the address of the post.
If you enter the address of the post, you’ll get information, and if you look at the top here, there’s a scrap time. If you look here, you’ll have time to see when you’ve scratched, and next to it is a button called Scrap Again.
By pressing this button, you will be able to update the image you changed because you will collect information again about the image you shared on Facebook. If you click Scrap again and watch it again, you can see that the scrap time has changed recently and see the changed image in <Link Preview>.
※ If you press the scrap again, it may not work immediately. It is recommended that you check the changes in the link preview and share them.
You can renew your representative image changes with the <Scrap> introduced above, but if it doesn’t work out, you can see it at the bottom of the Shared Debugger page, and it’s called the Open Graph Object Debugger. Once you get in here, you’ll find more information and renew your changes through Getting New Scrap Information at the top.
[ Briefly organized ]
1. Verify that the representative image of the site is set with the meta tag
2. Enter the URL of the post to be shared by the Facebook Developer Debugger
3. Check the image you entered as a representative of the shared post and click on the scrap again to renew it if it hasn’t changed.
4. Enter the Open Graph Object Debugger and click Get Scrap Information when the update is not successful
You will share a lot of posts on your blog or site with Facebook. But if you want to change the representative image by registering it incorrectly, please send the information through the above and change it.
