The April issue of our monthly newsletter covering some of the recent stories on web search and marketing trends has been published. This month's edition looks at the issue of improving web page load times, which will become an important factor for some Google AdWords advertisers since this element is now being included with the 'Quality Score' formula to determine advert rankings. It also looks at the process of creating weblinks and how the 'nofollow' attribute can have an influence on this process - and why it was introduced in the first place. Finally, following the completion of Google's acquisition of DoubleClick, the newsletter considers what this means for the combined business and the online advertising sector as a whole.
