If you want people to be able to share your site's content on LinkedIn, the source code on your site must meet certain requirements.
You need to make sure that the source code is compatible with the Open Graph Protocol (OGP) and certain LinkedIn-specific display requirements.
<meta property = 'og: title' content = 'Makalenin başlığı' />
<meta property = 'og: image' content = '// media.example.com/ 1234567.jpg' />
<meta property = 'og: description' content = 'Önizlemede gösterilecek açıklama' />
<meta property = 'og: url' content = '// www.example.com/ makalenin URL'si' />
The visual requirements specific to the LinkedIn sharing module are:
Maximum file size: 5 MB
Minimum image dimensions: 1200 (w) x 627 (h) pixels
Recommended ratio: 1.91: 1
<a href="https://www.linkedin.com/shareArticle?mini=true&url=http://www.example.com/page.php&title=Başlık&summary=ozet&source=kaynak"><span class="fa fa-linkedin"></span></a>
https://www.linkedin.com/shareArticle?mini=true&url={articleUrl}&title={articleTitle}&summary={articleSummary}&source={articleSource}
For the og: image property, make sure your file location is not protected or passworded.
