Introduction

This is an older and more comprehensive API version. It's peculiar properties:

• Authorization via API key

Traffic Overview data will be able to show you estimates of a website's visitor behavior. These include monthly visits, unique visits, pages per visit, average visit duration, mobile vs. desktop traffic %, and bounce rate.

In the same way, the Traffic Analytics Overview report can compare up to 5 domains at a time, you can pull this data for up to 200 domains in a single request using the Summary reports. This data gives you a quick look into the general level of interaction between a website and its visitors.

The extended API offers 8 distinct reports in addition to the Traffic Overview from the Basic API:

• Traffic Sources: the website traffic broken down into direct, referral, search, social, and paid traffic;
• Traffic Destinations: where users are going after visiting the domain you are looking at;
• Geographic Distribution: the countries, regions, or subcontinents where a website gets most of its visitors;
• Subdomains: the subdomains of the website that are responsible for acquiring the most traffic;
• Top Pages: the number of unique page views, unique visitors, entrances, and traffic sources for up to a site’s top 1000 pages based on traffic;
• Domain Rankings: top websites in the target location for the target period sorted by traffic;
• Audience Insights: additional visited domains, unique audience, shared audience %, and shared audience for the domains you entered;
• Data Accuracy: the estimated accuracy of the report based on the size of the domain and any filters you have applied (historical data, location, device).
• This data will show you more in-depth details of a website’s traffic for a more comprehensive study of a domain’s traffic coming from all angles.

You’ll be able to analyze traffic by source (search, social, paid, referral, and direct) and geographic location - including the top social network sites and search engines sending traffic to a site. This will tell you where a domain’s predominant market comes from online.

Subdomains will give insight into how a domain structures its website to attract visitors, and traffic destinations will show you what sites these people visit most often directly after the queried site.
