Online advertising costs

Hi
Was looking to find out ballpark figures for what you would expect to pay for online advertising. And is it possible to avoid going through the agencies?

Specifically I mean banner advertising.

Any examples at all would be a help.

Typical price for a good high quality website is €10 per thousend impressions (regardless of click through rate). You can deal directly with many similar websites (entertainment.ie, independent.ie, rte.ie etc.). However an agency might offer a better spread and design.

Other option is Google Ad's - your ad's will appear on sites and search results related to your product. Can typically cost from €0.10 to €1 per click on your advert (unless your a lawyer... in which case add a decimal or two!)

Just to illustrate my above examples better...

€1,000 might get you...

Advertise banner on independent, rte, entertainment.ie etc....

100,000 "impressions" and possibly 500 - 1,000 clicks

Advertise small ad format with Google Adwords....

125,000 "impressions" 3,000 - 5,000 clicks

Why have you singled out banner advertising? It is usually more applicable to "brand building" (e.g. Coke, Nissan etc.)... if you are a small/medium business or a niche operator, textual advertising with Google AdWords is probably your best bet.

PLEASE NOTE: I operate several small websites which are supported from Google AdSense advertising.
