Use Fixed Widget to create sticky widgets, sticky blocks, and other elements that stay in the visible screen area when a user scrolls the page up or down.
Sticky widgets are more visible than unfixed widgets and therefore have a significantly higher click-through rate.
That’s why this option is worthwhile for ads or other elements that visitors should interact with. Meanwhile, Google also allows the integration of <a href="https://wpadvancedads.com/google-adsense-sticky-ads/" rel="nofollow ugc">sticky AdSense ads</a>.

Fixed Widget and Sticky Elements for WordPress

I have used this plugin on my website for the last 5+ years and it always worked very well. Updates were always stress free and never broke any layout. 

With version 6 I had some layout issues and Thomas helped me fix it. It's really hard to make a plugin compatible with the vast amount of themes out there and I would have totally understood if he didn't want to spend the time to fix my specific issue. But I was in for a pleasant surprise. 

I recommend this plugin and I wish him all the best. Thank you for your time and efforts. 

Kind regards,
Arun

Worked very well for the last 5+ years and impressive support
