I have just installed PAN and I confess that I too am still trying to get my head around the procedures for selling and managing banner campaigns.
Like you, I also set up a zone in my theme.html for 468x60 full banners. I'm gonna try to sell space here as run-of-site on standard rotation for 3, 6 or 12 month duration. So at any one time I would hope to have between 5 and 10 different banners running in that zone, each from a different advertiser. That figure is arbitrary, I don't know if there is a limit on how many banners you are supposed to put into a rotation to keep advertisers happy?.
I can see that PAN enables you to manage campaigns by impression count (CPM), but all the sites I've seen selling banners that way seem to have serious vistor statistics to back up their sales pitch!.
As far as managing each banner, the plan is that when (or if) I sell the first banner, I will:
1) Set up an advertiser.
2) Add a campaign called '3 month campaign' or whatever and set the expiry date.
3) Upload the single banner to the campaign folder and link the campaign to the zone.
To add a second banner from a second advertiser to the rotation, AFAIK you simply repeat the process and link their campaign to the same zone.
If you add two campaigns like this and select Inventory/Publishers & Zones, then select the zone and click the 'Probability' tab, you'll see both the banners listed, each with a 50% probability value in the rotation. As more campaigns are linked to the zone, the probability figures change.
The nice thing about campaigns is that they enable you to sell advertisers 'double' or 'triple' rotation for their ad at a premium. You set this by changing the 'weight' value for the campaign, e.g. from '1' to '2'. So in a zone with 3 banners, a double-rotation campaign banner gets a probability factor of 50% and the other two standard-rotation banners get 25% each.
The other nice thing about campaigns is when the campaign expires, PAN stops displaying the banner and sends the advertiser an email telling them that their campaign has expired with an offer to renew.
To enable me to sell targeted banners, I have also set up a different custom sidebar block in each section of the site. In PAN I have a zone for each of these blocks. Once again, the plan is that the banners shown here would be in a rotation. These ads could actually be fixed (which is called, I believe, 'page sponsorship') but... I want to sell banner space via the website and a PayPal account. To sell page-sponsor space you really need to display availability, e.g. the 'News' section may be booked up for 6 months. Of course if you're taking telephone calls, I believe page sponsorship can be a lucrative deal to offer... especially when everyone wants to sponsor the homepage at Christmas!.
What Lloyd has done on the (very impressive BTW
) westcoaster site is create a column of DIVs in side blocks with each DIV linked to a different zone. From what I can see, these banners are fixed position, presumably sold for a time period.
Which method you use ultimately depends on the type of site. With rotation you take up less room of the page with banner ads, which can be an unwanted distraction for some people. With fixed positions, advertisers know their banner will always be seen by new visitors.
I would certainly like to know which method is the most successful!.
One tip I have learnt is that if you use campaigns to auto-expire banners, there is a possibility you might actually run out of banners to serve to a zone. If you look in the zone options 'Advanced' tab, you'll see the default action when this happens is for PAN to stop displaying banners.
To avoid this happening, I created a campaign called 'Default banners' with the site owner's name as advertiser. I didn't link the campaign to a zone but simply added default banners of various sizes and gave each a keyword, e.g. 'default_468x60', default_120x90' etc. Then in each zone, I changed the action to 'Select banners using the keywords below' and entered the appropriate keyword.
The other possible option - 'Display the selected zone instead' enables you to create a 'chain' and feed banners from another zone to one that has just run out of steam.
I hope some of this may have been of some help.
A thread is for life. Not just for Christmas.
