When comparing DuckDuckGo vs Presearch.org, the Slant community recommends DuckDuckGo for most people. In the question“What is the best alternative to Google search?” DuckDuckGo is ranked 2nd while Presearch.org is ranked 11th. The most important reason people chose DuckDuckGo is:
DuckDuckGo does not collect or share any personal information. Their [privacy page] has a great rundown on why privacy is important. The most important repercussion of this is that DDG doesn't use the data collected to tailor results, avoiding exposure to the "[Filter Bubble]". : https://duckduckgo.com/privacy : http://en.wikipedia.org/wiki/Filter_bubble
Ranked in these QuestionsQuestion Ranking
Pro Very protective of user privacy
Pro Allows searching from specific sites using bangs
Bangs are commands that allow searching via a different website's local search engine, using keywords or abbreviations with an exclamation mark (!). For example searching "world war ii !wiki" will automatically redirect to Wikipedia.org and show results for the query "world war ii" there, instead of DuckDuckGo, using Wikipedia's search engine.
The more common sites have shortened alternatives for these commands. Such as !g for Google, !i for images and !yt Youtube.
The whole list of bangs can be found by typing "!bang" in DuckDuckGo.
Pro Has a wide spectrum of instant answers
For select queries DDG pops up a box that supplies the exact answer. For example, searching "stopwatch" will pop up a stopwatch, asking for "words like..." will show a list of related words, typing "password" will generate a password, etc.
Pro Infinite scroll of search results
DuckDuckGo results page is an infinite scrolling page, so you don't need to be clicking through pages.
Pro Ads are non-obstructive and don't track you
The ads are clearly labelled as ads and are non-obstructive. The ads are based on the searched keywords and there's no tracking involved on their visibility. You just need to remember that the site the ad links to might track you.
Pro Many customization options for appearance
DDG allows customizing almost any aspect of the search engine's appearance including fonts, page width, alignment, header behavior, site icons, etc and has a selection of premade themes available as well.
Pro Can disable advertisements
The search engine allows freely disabling ads.
Pro Has a .onion site
Only accessible from Tor.
Of course, it's nicer when enabled, but it's not required. Some browsers are too limited (mobile, terminal) or turn it off for security reasons (tor, etc.), and DDG still works.
Pro Good for Linux users
DuckDuckGo has an API with some websites. With the help of this API, if you search for a fix of a problem in Linux, you can easily find an answer to the problem. For example, if you search for "How to update linux", you will get a message like this:
How to install updates via command line
sudo apt-get update # Fetches the list of available updates
sudo apt-get upgrade # Strictly upgrades the current packages
sudo apt-get dist-upgrade # Installs updates (new ones)
Pro No filter bubble
DuckDuckGo does not filter your search’s with the data that they have. You get to see everything the Internet has to offer in a safe, private way.
Pro Sometimes results are better than Google
Sometimes the search results are better. Most of the times, they're at least as good as.
Allows users to earn tokens for searches conducted on the platform.
Pro Community driven
The algorithms are provided by the community allowing for transparency and no manual manipulation.
Users can choose which engines they use most (i.e. Github for developers or image searches for artists).
Pro Easy working and customer friendly
Con No date information in search results
In search results, there are no dates when the pages were published, which doesn't allow you to immediately know if the page is outdated.
Con Horrible search results
They store no information about you (theoretically a pro) but this results in absolutely awful search results, and having to modify your search terms 4-5 times to get what you are looking for.
Con DuckDuckGo has no 3rd party certifications
A referrer is an HTTP header field that identifies the address of the webpage (i.e. the URI or IRI) that linked to the resource being requested. By checking the referrer, the new webpage can see where the request originated.” Basically it tells a website where you came from. DDG does give this out.
Con Owner would compromise his service/customer privacy
In a question to Weinberg, “if you were served an NSL or were commanded to compromise your service/customer privacy in any way, would you and could you just pull the plug like Lavabit did or would you run into opposition from shareholders/investors that would prevent you from doing so?” Gabriel Weinberg said: “No one is preventing me from doing that.”
Con Based in US, so they cannot guarantee there is no backdoor
Con Shows too few images
When searching for images only, it shows too few of them and only a handful are related to the search terms.
Con Needs a clearer vision of the future
What's duck's goal or quest?
Con DuckDuckGo and Yahoo Partnership
Con Still not better than Google
Results are quite often not as good. They just lack resources to do it, for now.
Con Search using language other than English is not so great
Korean would never use it.
Con Bangs do not protect user privacy and can be misleading
Using these bangs will instantly connect you to the service you requested. For example typing “!g white cat with green eyes” and hitting return, drops you off on the Google website to display your results (thus logging your IP, search term and browser info immediately). It does not get you Google results inside DuckDuckGo. It is reasonable for DDG users to assume and expect a private search engine warns if there is a risk to that privacy being lost, like it does with Youtube videos but in the case of Bangs this does not happen.
Con Hosted on Amazon servers (EC2)
Con Form over function (overall search experience is poor)
It's nice to adjust the settings and all but after a couple of days you will want to go back to a more functional search engine.
Sure DDG looks shiny and !bangs are great but many wouldn't consider it as a viable alternative. Better results for search queries is more important than fancy looking CSS.
Con DuckDuckGo has many 'Owners'
DuckDuckGo is owned by Gabriel Weinberg who is is the founder, current CEO and controlling shareholder. Investors/shareholders include Union Square Ventures and several others(https://www.crunchbase.com/funding_round/duck-duck-go-series-unknown--5d9c6644). DuckDuckGo generates it’s income from advertising (Bing Ads) and collects affiliate revenue (Amazon, eBay).
Con Search results are often unrelated and limited
Common conversions do not work, i.e. searching for 15F to C does not give you the conversion but just a bunch of conversion websites. Very frustrating. It's a simple thing but makes a huge difference to the browsing/searching experience. Also location based only works for the country you're in. Searching for, say, McDonalds only gives country results for McDonalds and no local results such as where a local restaurant may be. Not very helpful.
Con Doesn't do personalized searches
Since they don't track you the results are not tailored to your interests.
Con Bing = DuckDuckGo
It uses Bing for the query.
Con Cloud saving still needs work
Cloud save and the ability to pull up your settings on any device is a nice idea but the implementation needs work.
Con Requires to login to use it
You can't even read the "About" section without creating an account.
Con Portal vs. Engine
It's currently a search portal; the engine is scheduled for release sometime later this year.
