Sorry Twitter, You Are Not a Search Engine

Nothing to see here my SEO brethren

(Guest post from Marc Bitanga)

As anyone NOT living under a rock would know, there has been all sorts of hype around Twitter, and rightly so. Recently Danny Sullivan reported from Twitter’s Chirp conference that Twitter has reached 19 billion searches per month. Wow. Not bad! That’s a big number for a 3 year old company. Here are some staggering stats:

  • Twitter is processing over 50 million tweets/day
  • The 3 year old social network has over 100 million users
  • There are over 70,000 registered apps that use Twitter’s API
  • In 3 short years, they’ve reached over 10 billion tweets

So the figures are there to back up that Twitter is a game changer. But is it a Google killer?

As this information was published, there was quite a bit of oooh’s and ahh’s over this very large figure. With some suggesting that Twitter search could support a profitable pay per click advertising platform.

But we’ve got to ask. How good is Twitter as a search engine? Does it rival Google for information retrieval? Would a Twitter pay per click platform rival Google Adwords?


The Twitter Search Engine Test

19 billion searches per month is undoubtedly quite impressive. Especially when considering that figure outpaces both Yahoo & Bing combined. Since Twitter search is being compared to Google, I was curious to find out whether Twitter can rival Google as a search engine. And whether pay per click advertising is a viable way to monetize Twitter search.

I ran a few quick test queries to study Twitter’s search engine prowess.

A popular and profitable sector for Google is the travel & accommodation category. I used this as the basis for the test. Let’s Look for a Hotel in Seattle….


Search Query: “Seattle Hotels”

Twitter Search; Seattle Hotels

The 10 most recent results seemed to have some useful resources. However, the results lacked credibility. Here are some observations:

  • Twitter search retrieves results from anyone tweeting about the subject whether or not you are following the user profiles. Therefore the results haven’t been curated by your network of friends. The network that you follow is probably Twitter’s biggest strength and resource for personalization, but it isn’t being utilized in their search engine.
  • There’s no real algorithm to see here other than the most recent timeline. This can be easily gamed by spam accounts.
  • Another issue with Twitter’s search results is that if a tweet contains a link they are usually cloaked by shortened URLs. Viewing shortened URLs from your network of friends is fine. But viewing a list of shortened URLs from a list of unknown users can be iffy.


Search Query: “Seattle Marriott Hotel”

Twitter Search; Seattle Marriott Hotel

No search results for the search query. If Twitter is serious about attracting advertisers to a search based pay per click advertising platform they’ll have to be a reliable source for information. If the search engine doesn’t retrieve any results for the most basic of search queries, then it isn’t much of a resource.

Search Query: “Seattle Marriott”

Twitter Search; Seattle Marriot


The results were a grab bag of different types of tweets.

  • There were some foursquare results from people checking into a Marriott location.
  • Some results were for job postings for the local hotel.

But let’s break it down further:

  • Twitter contains quite a bit of noise. Such as foursquare tweets that aren’t really helpful to a random person searching.
  • Twitter search doesn’t attempt to decipher the user’s search intent. From a logical perspective, a person searching for “Seattle Marriott” is likely looking for accommodations, not a job.


Search Query: “Seattle”

Twitter Search; Seattle

I tried a much broader search query more out of curiosity than anything else. Again, not the most helpful search results.

Overall Findings

And the result? Google doesn’t have anything to worry about for the time being. Twitter is not a search engine.

I ran a several more search queries with the mindset of a traveler, both from a national and local perspective. I found the experience to be hit or miss. If you try to use Twitter in the same manner as you use Google, Bing or Yahoo you will likely be disappointed.

Here is why:

  • Twitter search doesn’t have an infinite index. You are limited to the messages that people broadcast and the links they share. As a result there are gaping holes when performing some basic search queries.
  • It’s not reliable. Since the twitter index contains gaps, it’s not a reliable source of information. This makes you think twice before using it for practical purposes.
  • It doesn’t have a very sophisticated algorithm, which leaves it open to spam. Here is what we know about Twitter’s search algorithm:
    • Search queries will typically yield a set of results based on the most recent timelines.
    • Twitter will promote the most popular tweets (messages that have been retweeted several times), even if it is a few days old.
  • The search engine doesn’t analyze the intent of the person searching. This results in a broad spectrum of search results for certain queries.
  • Twitter search has a duplicate content problem. If you happen to search for a phrase that’s contained in several retweets, Twitter will show those messages in the search results.
  • The search results lack credibility. Two factors add to this credibility issue.
    • Spam accounts – Accounts with no avatar or with names that look suspicious.
    • Cloaked URLs – URL shorteners hide the real URL. This isn’t an issue if you trust the person sending the message, but when presented with a link from an unknown user you might think twice before clicking it.
  • The Twitter index contains too much noise. Conversational tweets between users also occasionally appear in search results.

Twitter’s search function doesn’t fit the mold of a search engine. It’s quite simply a site search feature for an extremely popular social network. Does this mean that the search engine doesn’t have any value? Twitter search does serve a purpose. It’s an excellent source for finding information for real-time trending topics such as:

  • The latest celebrity or pop culture news – The death of Michael Jackson
  • Commentary related to current events – 2009 Iranian protesters
  • Natural disasters – Recent California earth quakes

Twitter has mentioned it has no plans to have a comprehensive index. They will likely focus on improving the relevancy of real-time tweets.

As for whether Twitter can monetize the use of their search engine, without access to keyword research data it’s difficult to tell user behavior and user expectations from Twitter search. However based on these findings, Twitter has a bit of work to do to improve the relevance of their search engine before it can be considered a Google killer.
