首先我們必須先找出一個成本函數，其值的大小可以代表一個企業的網路行銷諸活動是否有效率。可能的網路行銷活動，至少包含:加入網路市集、進行網站排名優化、及購買網路廣告。而網路廣告又可區分為橫幅廣告、關鍵字廣告、內容廣告等。如果企業想要推廣的目標是一項產品，而不是品牌的話，可用每次目的網頁被點擊的成本(Cost Per Click, CPC)來做為成本函數。能達成目的網頁最低CPC的預算分配方式，就是一個最佳的網路行銷規劃。所謂目的網頁就是通常只有企業要的客戶才會到訪的網頁。
通常最佳的行銷規劃都是由多項行銷活動所組成。例如：既加入市集網站也購買網站排名服務後，所得到的平均點擊成本，會比只購買一項服務的平均點擊成本低。這是因為加入網路市集也有助於提升網站的排名。
亞普達有十年以上，經營市集網站allproducts.com與提供網站排名服務的經驗。並且是Google在台灣的第一家代理商。在台灣有九十多位經 Google認證過的網路廣告專家(GAP)，就人數而言，在全球是排第一的。其中有半數受過WMO™訓練，可以在北中南就近服務有需要的企業。
Using a single number to indicate the effectiveness of a company’s web marketing activities has the advantage that enterprises can evaluate and compare their marketing effort efficiencies easily. Possible web marketing channels include but not limited to: online marketplace, search engine optimization, and online advertisement. Online ads can be further classified into banner ads, keyword ads, content ads etc. If the promoted target is a product instead of a brand name, average Cost per Click (CPC) on the destination page is a good index to measure the effectiveness of the web marketing activities. Where the destination page is a page usually only targeted customers will visit.
The optimum is usually a combination of multiple marketing efforts. For example, the average CPC after joining a marketplace and purchasing search engines optimization service is usually lower than the average CPC of doing only one of them. This is because joining a marketplace also improves the ranking at search engines.
Allproducts.com has 10 years of experiences in providing marketplace and search engine optimization services before it becomes the first authorized reseller of Google AdWords in Taiwan. More than 90 employees are Google Authorized Professionalists (GAP) of online ads.
