Selective Truths

Do Iran’s homemade search engines tell the truth, the whole truth, and nothing but the truth?

In mid-February, Iranian officials announced the launch of three domestic search engines, which they claim can be used without any interference from the filtering system. This month’s report puts this claim to the test by searching for some sensitive keywords on Iranian search engines and comparing the results to Google.

It won’t come as a surprise to readers that our findings suggest that Iranian search engines do indeed filter results for some sensitive keywords. However, it turns out that this filtering sometimes works in unexpected ways, and other times results we thought might be censored were actually pretty easy to find.

We think this report offers some introductory insights into how Iranian search engines work, and how they interact with the country’s filtering system.

In recent years, Iranian officials have championed ‘national’ tech development projects (such as the National Information Network (SHOMA) and Iranian versions of Western services), while eschewing foreign platforms like Viber and WhatsApp.

One of the most recent examples of this dynamic can be found in the February 2015 ‘launch’ of three Iranian search engines: Parsijoo, Gorgor and Yooz. While the launch of these three search engines was announced in February, it should be noted that Parsijoo was in fact launched a few years ago, and Yooz was launched in early 2010. It’s unclear why the authorities are presenting them as ‘new.’

According to Iranian officials, the core feature of all domestic search engines is that Iranians can use them without any disruption from the filtering system, regardless of what terms they search for. The authorities also maintain that these search engines can compete with Google and other Western alternatives.

Small Media sought to put these claims to the test by performing a series of searches for potentially sensitive keywords on these three search engines and Google. Before delving into the results of our study, here’s a bit of background on the search engines we looked at.

An Overview of Iranian Search Engines

According to the Deputy ICT Minister for Strategic Planning and Control, Barat Ghanbari, Parsijoo was developed by Yazd University in cooperation with the ICT Ministry, which provided 150 servers and agreed to cover all maintenance and bandwidth costs. Although the stated plan was to launch Parsijoo in February 2015, the platform was in fact active five years ago. It is unclear why some of the authorities described it as a new search engine.

Gorgor was created by a team at Imam Hossein University, which has close ties to the Iranian Revolutionary Guards Corps (IRGC).

Finally, Yooz was developed by researchers from the following universities: Sharif University of Technology, Tehran University, Amirkabir University of Technology, Shahid Beheshti University, Iran University of Science and Technology and Tarbiat Modares University. It was launched in early 2010.

We picked six potentially keywords: ‘sex,’ Baha’i,’ ‘Mir Hossein Mousavi,’ ‘BBC Persian,’ ‘Facebook,’ and ‘VPN,’ and searched for them on the search engines mentioned above plus google. Here’s what we found.



Parsijoo appears to be the most heavily-censored of the Iranian search engines, as it seems to block all results for the keyword sex.

Meanwhile, GorGor’s first page of results included links to pages about erotic stories, various sex position, and the dangers of anal sex. The results offered by Yooz are similar to those of GorGor, while they also include a blog post about why some women do not like oral sex and a documentary about sex in a Sigheh, or temporary marriage. Google, on the other hand, provided links to pages with “sexy images,” and “the most viewed sex videos.” So sex-related searches seem to generate different results on Iranian search engines than they do on Google. But does this disparity hold when the keyword has to do with religion?


Baha’i is another interesting keyword, and the results of this search suggest that Iranian search engines are reluctant to feature much pro-Baha’i content. Results on all Iranian search engines are overwhelmingly hostile to Baha’is, with many referring to them as “the misguided Baha’i sect.”

Google, on the other hand, offers more balanced and neutral results: the top three results are from Wikipedia, the fourth is the website of the worldwide Baha’i community and the last 5 results are opposed to the faith.


With sex and religion out of the way, lets now turn to politics. How did Iranian search engines deal with searches for Green Movement leader Mir Hossein Mousavi?

Although Iranian search engines seem to pull in Mousavi-related Wikipedia pages indiscriminately, the majority of non-Wikipedia content on their front pages are news articles from before Mousavi’s house arrest, or editorials criticising his political activities. None of the articles concern his criticisms of the Ahmadinejad government, or claims of electoral fraud in 2009. More than 40% of Google’s front page results concern these topics.

Put another way, when Iranian search engines weren’t pulling content from Wikipedia, they seemed to be excluding results that might challenge the government’s line on sensitive political matters. Turning now to searches for BBC Persian, we encounter a more subtle and insidious form of censorship.


Not only do Yooz and GorGor offer no links to either or, but the majority of results on Yooz actually direct users to, which is a fake version of BBC Persian.

The real and fake BBC Persian pages look very similar. See if you can tell which is which. Here’s the first one, which we’ll call Image I.

And here’s the second, which we’ll call Image II.

Give up? Image I is the fake BBC Persian, and Image II is the real one. If you don’t speak Persian, you’d be forgiven for struggling with that question. But if we translate the top three headlines on each page from April 17, 2015, it gets a bit easier.

Top three headlines: Real BBC Persian

  • Pakistan’s Parliament disagrees with military operation in Yemen war
  • Engine of Iran’s commercial aircraft exploded in Istanbul airport
  • 7 Pakistanis killed in Syria were buried in Qom

Top three headlines: Fake BBC Persian

  • BBC insists on justifying crimes of terrorism in East of the country
  • BBC tries to exploit death of Khatami’s mother
  • BBC praises ISIS

So while the real and fake BBC Persian pages look very similar, a look at the top three headlines for each reveals a sharp contrast in editorial orientation. It seems that Iranian search engines are trying to deceive users by sending them to fake pages. Turning now to searches for online social networks, a similar form of deception begins to emerge.

Online Services

As with BBC Persian, searches for social networks like Facebook and Twitter often direct users to artificial knock offs. For example, whenever users search on Parsijoo, Yooz or GorGor, they cannot find links to Facebook or Twitter. Instead, users are directed to Iranian versions of these websites via links such as:,,

While these search engines seem to be designed to hide the URLs for Facebook and Twitter from users, some of them actually display these URLs on the top of the results page. For instance, you cannot find among Yooz’s search results. However, the top of the results page contains a brief description of Facebook, followed by a link to

So while the search results try to direct users to Iranian social networks, the description at the top of the page contains a link that leads them straight to the real Facebook! It’s difficult to say whether this oversight stems from carelessness or incompetence, but it seems clear that such sloppy attempts at censorship wouldn’t be difficult for even the least tech savvy Iranians to circumvent. Speaking of circumvention, lets see how Iranian search engines handled queries for VPNs.


Unlike most of the terms discussed above, the results for searches for VPN on Iranian search engines and Google are very similar. Yet while Iranian search engines don’t appear to censor results for VPN related searches, it is possible that when a user clicks on one of the links, he or she will be blocked from accessing the VPN selling site.

In addition, you can find lots of video tutorials regarding VPN use on Iranian search engines which are hosted on Apart, an Iranian version of YouTube. So it seems that for all the censorship discussed above, Iranian search engines are surprisingly forthcoming as far as queries for circumvention tools are concerned.


What conclusions can we draw about Iranian search engines? It seems clear that domestic search engines form a new part of Iran’s vast internet filtering apparatus. As we have seen, searches for sensitive keywords, such as Baha’i, yield considerably different results on Iranian search engines than they do on Google.

For some users, this disparity will be a good reason to distrust Iranian search engines. Their familiarity with Google’s results for a given search will make it easy for them to spot a heavily filtered domestic alternative. Moreover, the fact that Yooz carelessly included a link to Facebook at the top of its results page suggests that many netizens won’t have too much trouble circumventing censorship efforts. However, we can’t assume that all users will be so critical or astute.

Those users who credulously turn to Yooz, GorGor, and Parsijoo with their online queries could easily be lead to believe false or misleading information. Moreover, even critical netizens may struggle to tell the pages for the real BBC Persian and the fake one apart, as they look remarkably similar.

Directing users to a fake, government-controlled version of BBC Persian constitutes a subtle and insidious form of censorship which could lead users to accept baseless propaganda as fact.

In an age when so much of what we know about the world comes from online media sources, exercising control over which websites users see and which ones they don’t endows search engines with considerable power. And when the Iranian government uses that power to promote a specific ideological agenda, the internet freedom of Iranian citizens suffers.
