AdWords is Google’s flagship advertising product and one of its main sources of revenue.
AdWords offers Pay per Click (PPC) advertising, as well as site-targeted advertising for both
text and banner ads.
Pay per Click Advertising
Advertisers specify the words to “trigger” their ads and the maximum
amount they are willing to pay (or bid) per click that they receive. When a user searches on Google, ads
for relevant words are shown as ’sponsored links’ on the right side of the
screen, and sometimes above the main search results.
The AdWords program includes local, national and
international distribution options and a huge variety of configurable options when setting up and running your Ads. Google’s text advertisements are short, consisting
of one title line (max 25 characters) and two content text lines (max 35 characters each).
The order of paid listings depends on other advertisers’ bids and the ‘quality score’ of all ads shown for a given
search. The quality score is calculated by Google from a number of factors including historical click-through rates and
the relevance of an advertiser’s text, keyword and landing page to the search.
Site Targeted Advertising
A few years ago Google introduced site-targeted advertising. Via the AdWords control
panel, advertisers can enter keywords of interest. Google then offers to place
ads on sites advertisers consider relevant within their content network.
Advertisers then bid for placement, and can also build a list of sites
where they do not wish their ads to appear. It is not currently possible to obtain a list of sites
where their ads could appear), however it is possible to see a report of where their ads
showed and how many viewings and clicks were achieved.
Google Adwords can provide a very effective and relatively low cost means of building traffic for your website, and can be particularly effective for new sites, as a way of getting traffic while their organic (natural) rankings build up.
