Most of these optimization tips is also applied to Adsense
ad units as well so they may not be new to you:


1. Text color for the link unit should be the same as the link
color for your website.

2. Remove the ad borders and make the ad background color
matches your site. This will increase the potential for
blending and clickthroughs.

3. Above the fold placement or placement of link units near
the top of any webpage will work best for link units.

4. Avoid Ad Congestion and clutter. Link units should not be
placed too closely to other advertisements because they
may be easily overlooked by visitors. Link units work best
when placed to navigational links or as standalone units.

5. Optimize for Search Traffic. Link Units work best with
visitors from search engines and should be placed on pages
which receive the most consistent search traffic, even if you
don’t want to use them on a site wide basis.

6. Use Ad Channels. Ad channels allow you to measure the
performance of each link unit you use and allows for
comparative analysis.

7. Mirror your site link structure. One useful way to improve
your link unit click through rate is place your link unit
beneath or beside your on-site navigational links. This
conceptually makes them blend in extremely well although
they may confuse visitors.
