Methodology

Our evaluation process is very strict and based on factual data to be as objective as possible.

We evaluate all the website manually, following a strict checklist, but some data are scraped automatically to enrich our database and to be able to deliver more accurate search results.

Rating System

Our rating system is based on 9 quantitative metrics:

  • Content Quality
  • Content Quantity
  • Content Available
  • Search
  • Player
  • Layout
  • Ads
  • Legality
  • Love Factor

Those metrics are ranging from 0, being the worst possible score, to 10, being the absolute best. Those scores is what makes it possible to compare, rank an order a website with another.

The rating is the average of those 9 core metrics.

Metrics description

Content Quality

This metric evaluates the quality of the content. For a video site for example, we will take into account the average length of the videos, the resolution available and the originality of the content.

If a site has more than one type of content, for example a video site who also has an images section, we will rate only the main type of content.

Content Quantity

This metric represent the quantity of content available on the website. To rate the websites fairly, each type of website has its own scale. For example, a website specialized in a sub-niche of porn will need fewer videos than a general site to get the same score.

Content Available

For a lot of porn sites, missing resources is a very real problem. You click on a thumbnail, and then you get a 404 missing resource error. This metrics represents the degree of link rot.

Search

How good is the search bar? Can you filter and sort your search results? Does the site have a tagging system and good categories? Can you browse by porn star, channel or playlist? Through all those questions, this metrics represents how efficient the site is at letting you find precisely what you are looking for.

Player

This metrics evaluates the quality of the player. The things taken into account are the speed of the video buffering and the reactivity of the player. The features offered, like a previews thumbnail or a resolution setting menu, also have an impact on the final note.

Layout

Is the site pretty? Is the site easy to navigate? Can you find the features you need easily? Does the colors hurt your eyes? As you might have guest, this metrics reflects the quality of the design from an aesthetic and functional standpoint.

Ads

This represents how the ads are impacting your experience when you browse the site. Keep in mind that a high score is always good, so for this metrics a high score means that the ads are not annoying.

Legality

Does the website abide by the law, or is it a nest of pirated material? This metric takes into account the presence (or the absence) of a DMCA page, a privacy policy, terms of service... It also takes into account the general reputation of the site when relevant.

Love Factor

Because some times the 8 other metrics alone cannot fully explain why we love (or hate) a website, we introduced the love factor. This is the least objective of those 9 metrics, but we still deem it important to fully reflect our take on a website.

Collected Data Points

Besides our core 9 metrics used to evaluate a website, we also collect some other information about the website to allow for data search and classification. Those data points may or may not be correlated to one or more of our 9 core metrics.

Content Types

This classification reflects the type of content you can find on a given website.

  • "videos": video content. This content can be clips, scenes or movies.
  • "clips": short (or long) extracts of a longer video. The main content of most tubes sites. This is a sub-type of "videos".
  • "scenes": this tag is reserved to websites dedicated to full scenes only. This is a sub-type of "videos".
  • "movies": this tag is reserved to websites dedicated to full movies only. This is a sub-type of "videos".
  • "images": for websites where you can browse catalogs of images.
  • "stories": text based stories.
  • "cams": for websites dedicated to live webcams.

Most tubes sites will be given the "videos" and "clips" tags only, even if you will be able to find some full scenes and movies on them, to reflect the main content of the site. The "scenes" and "movies" tags are reserved for sites dedicated to only those types of content.

Tags Assignation

To help classify the websites, we assign them some extra tags. Those tags are generally related to the core nature of the website. Here are the main ones:

  • "mega-site": a very big site, both in quantity of content and in traffic. Usually big names of the industry like Pornhub.
  • "general site": the opposite of a niche site: a site who is not specialized.
  • "niche site": a site whose content is specialized in a particular niche.
  • "streaming": a website will get this tag if its content can be consulted online.
  • "download": a website will get this tag if its content is made to be downloaded. For example a blog collecting Rapidshare or k2s links, or a torrent site.
  • "search-engine": a porn search engine to explore the content of other websites.
  • "aggregator": an aggregator website is a website that aggregates the content of other websites. When you try to access a resource, most of the time you are redirected to the website hosting this resource. But an aggregator can also use embeds instead.
  • "false-redirects": a website will get this tag if, when you click on a thumbnail, instead of accessing the video you are redirected on another site, unrelated to the content you where trying to access. This is not done to flag the aggregators, but instead to get the websites that use shady traffic rings.
  • "virus": a website will get the "virus" tag if my anti-virus popped up during the site evaluation. It is not a direct cause of rejection because hey, those are porn sites and you will get shady ads from time to time, but so you know.

Business Model

This represent the business model of the website. The possible values are:

  • "free": the website if free.
  • "freemium": the site is free, but there is a paid tier available, usually to access some more qualitative content and remove ads.
  • "premium": you have to subscribe to the paid offer to consult he content of the website.

A website tagged as "freemium" will almost always also get the "free" tag.

Orientations

The possible values are:

  • "straight": the website has some straight content.
  • "gay": the website has some gay content.
  • "shemale": the website has some shemale content.

A website can be marked for just one of those orientations, but also two of them or even the three together. If a website is marked as having "shemale" content for example, it can mean that it is a website dedicated to this kind of content, but it can also be the case that the site has a "shemale" section (dedicated part of the site with some sub-categories), or just a "shemale" category. To be able to fully differentiate between the three possibilities, we have to also look at the niche and the categories.
