Frequently asked questions

What is URL Classification?

URL Categorization or URL Classification is the process of providing the category a Domain or a URL belongs too, for example, for the domain cnn.com the domain classification is: “news”.

Who needs URL Classification?

URL Classification is used by vendors that provide software such as: Parental control, DLP (Data Leakage Protection), gateway protections, also it can be used to improve advertising performance for: RTB (Real Time Bidding) advertisement, brand safety and segmentation of users web surf habits for more accurate targeting of advertisement.

Do you classify websites per URL?

Regarding per URL classification, there are two ways of classifying the URL:

  1. Provide the classification of the domain, regardless of the page’s content, for example every page in cnn.com will be classified as “news”
  2. Actually classifying the page and providing the classification specific for that page, regardless of the domain’s main category, for example an article in cnn about finance will be classified as: “news,finance”

What kind of per URL classification do you provide?

We are able to provide both options. The option to classify the content of the page costs more as we need to request the URL in real time, and analyze it. We must request every page so we can analyze each of them separately.

Do you classify web searches?

Yes, the server detects when a URL is for a search engine and part of a search query, then it will extract the keyword and classify the keyword within the database of over 20 million keywords and phrases in 20 languages.

Do you classify keywords or phrases?

Yes, we classify both. The server can accept a single keyword or a phrase for classification.

Do you classify websites manually?

We classify the top sites manually, but our proprietary algorithms classify 99% of our database. This allows us to add new categories very fast, and let the algorithm update our database.

How do you handle a new website that is not in your classification database?

When we get a request for a new website, the server classifies it on the fly (so you don’t have to wait for someone to review it) and adds it to our sites database.

Do you classify images?

No we don’t. We classify the whole website based on the text content of the site.
It’s important to understand that images are coming in context (HTML, search phrase) and the context is what determines the category.
