Introducing New SimilarWeb APIs!

The quality of SimilarWeb’s data makes us unique and gives us our competitive advantage. Therefore, we are proud to announce that we will be exposing more of our data to our APIs in order to give developers the opportunity to integrate our web traffic and content intelligence into their applications and websites.

For the past several months, we have given developers access to our global, country and category rank, as well as our proprietary SimilarSites, tagging and categorization technology. Developers have built some amazing products (here’s a great example) using our data, but we kept hearing that you wanted more access to the data that makes SimilarWeb the best competitive intelligence tool on the internet.

We listened to your suggestions and worked hard to make almost every web metric you see on SimilarWeb accessible by an API. We’ve also added metrics to our existing APIs, giving you more data per call. For example, our brand new Traffic API doesn’t only return a site’s global rank, but also gives you country rank, traffic geography, traffic reach for 6 months and traffic sources distribution.

Our new APIs are:



Traffic API

Returns a site’s global rank, country rank/traffic geography, traffic reach and traffic sources distribution.

Engagement API

Returns a site’s average page views, average time on site and bounce rate.

Keyword Search Intelligence API

Returns a site’s paid/organic search distribution, 10 paid keywords, and 10 organic keywords.

Leading Referring API

Returns the 10 leading sites that direct clicks to the given domain.

Leading Destination API

Returns the 10 leading sites that receive direct clicks from the given domain.

Social Referral API

Returns the five leading social networks sending traffic to the given domain.

Also Visited API

Returns a list of websites frequently visited by users of the given domain.

We are, of course, keeping access to our popular content analysis APIs including:



Similarsites API

Returns 20 similar websites and their similarity score for a given domain

Categorization API

Returns a given domain’s category based on our content analysis and machine learning.

Adult Categorization API

Detects the presence of adult content for a given domain

Category Rank API

Returns a domain’s category and its global rank within its given category

Tagging API

Returns 10 tags per domain based on semantic analysis, meta-data, anchor text and more.

New pricing packages that provide more calls/month

We wanted to provide affordable access to our data and have overhauled our old pricing structure for a new model that provides additional value for our customers.

We now have three packages available, ranging from $99 per month for access to our traffic intelligence metrics to $599 per month which gives access to all of our APIs, including our industry leading content analysis data, and allows for 100,000 hits per month. We also offer a $199 option which provides access to 25,000 hits per month.  For customers that need more calls, we are always willing to discuss volume discounts. We want as many developers to integrate our data as possible we worked hard to come up with a pricing model that provides affordability and flexibility for our users.

Easy to integrate and test

Our RESTful APIs return easy to read responses in either XML or JSON and we provide an easy to use, graphical testing console for experimenting with our APIs.

We can’t wait to see what you’ll build
