Using the Google Adwords Traffic Estimator API , we need a standalone app to be built that can fetch the estimated traffic for certain keywords for a certain region.
You can access the Keyword tool at https://adwords.google.com/ko/KeywordPlanner/Home .
For the app interface we need a text area in which we can input keywords separated by comma (,) and below it 1 submit button.
When the submit button is clicked, the web-app needs to communicate with the Google Adwords Traffic Estimator web service to get an estimated search volume per keyword (per month = default). The volume should only be from Belgium and in Dutch (see screenshots in attachment for parameters set).
After the script has processed all keywords entered and retrieved data for all entered keywords, then display the results in a simple HTML table with 2 columns: keyword & traffic per month. We require no extra functionality (no security, no database, ...). Only for Google Web service authentication, you put the authentication parameters at the top of the file and we will replace them with our account info.
The web-app needs to be written in PHP5 and to communicate with Google Services, you can use OpenSource library for this (from Google or other party).
see for details for development: https://developers.google.com/adwords/api/docs/reference/v201306/TrafficEstimatorService.AdGroupEstimateRequest#keywordEstimateRequests
The web-app will be implemented into a larger platform, this is not part of this project.
Also no design work or layout is required: just use default HTML elements and their default layout.
