Google never tells so and its impossible to track link unit clicks . So nobody can tell ; but yes it improves your CTR and thus revenue
Why not create a channel for your link units and test it out yourself? In my experience it seems that on average they pay about the same as the normal ad units. However the visitor needs to click twice, once on the link unit and once on the ad displayed. That being said, they normally get a larger selection of ads displayed, so chances are they might something interesting to click.
I can say that all of my link units, either horizontal or vertical (blended in the sidebar) have higher CTR than normal ad units and they don't usually pay less.
in my experience, the link units pay slightly higher than my other content ads, but my CTR is much lower on them.
Do Adsense only pay when they click on one of the links on the list after they click on the ads unit? Or it do pay whenever the ads unit is clicked, no matter the person click any links on the list?
You only get paid when the visitor clicks on the Ad not on when they click on a link. In other words, you get paid for the "Second click".
One one of my sites I'm gonna give the link units a try and create a channel so I can track their earnings. I'll try to post back with an update on this thread in a few weeks.
so i see you needa click the link unit twice to get credited.. so when they click once does that count as a click? my CTR is high but my earning is low
I rarely get that second click. A lot of people have the greatest success with link units, i guess it just depends on your site
Link unit did a great job on my earnings. Especially for those people who don't know about adsense. I suggest you have to experiment on these. It really depends on what type of visitors you have.
For me the link units appear to pay slightly lower than regular ads, but my CTR for link ads is higher than for the regular ads so it evens out in the end. By looking at my channels and stats it appears that those who do click the link unit ads often click more than one of the ads on the results page. Link unit ads are so specific to a keyword that they help the visitors to find exactly what they are looking for. My thought is that if the visitors are looking for an extreme niche or specific product that they are more likely to find it with link units than general ad units. Just experiment with the channels and see what works for you.
