Tuesdays on AltSearchEngines we host our Debates, and this week we are pleased to welcome Yannick Laclau of Properazzi and Gary Stewart, CEO of Migoa/Nuroa.  This debate expands upon our earlier interview with Yannik.



1.  Vertical search engines really seem to be taking off, can you just summarize a few of the challenges that are unique to Property/Real Estate Search Engines (as opposed to People Search or Job Search Engines).

There are many challenges, but fundamentally these are the same for search engines in any vertical: finding and adding fresh content; identifying and removing bad content; accounting for duplicate data; processing search queries quickly. If you’ve solved the fundamental problems, then you can apply them to any vertical without too much trouble. Properazzi are already very advanced down this path already in real estate, with technology that indexes 4 million listings from 11,000 different agency websites.

The main challenge for a property search engine is a variation of the general problem faced by many disruptive start-ups: How do you make yourself known and differentiate yourself when there are powerful web 1.0 property incumbents already online? There are obvious differences between property search engines and web 1.0 real estate portals, but how do you convince consumers that they should care? A lot of consumers are already accustomed to behemoth companies like Rightmove in the UK (a listed company with a market cap of more than €1 billion) or Seloger in France (also a listed company with a market cap upwards of €700 million), and these companies have enough money to out-spend us and enough brand recognition to pose a significant entry barrier. In addition, vertical search engines aren’t a particularly viral product like Facebook where customers have an obvious incentive to return every day and share it with all of their friends. 

So getting the customer to the product is the main challenge when there are powerful incumbents with well-established brands who don’t have cutting-edge products but their products are still more-or-less okay for the average Internet user. Once the customer gets to our product, it’s fairly easy for her to understand how a property search engine like nuroa will make her life a lot easier and disrupt her prior real estate search experience. But the main initial challenge is getting her there. Other than that, there are specific problems related to making sure that our results are precise, relevant and exhaustive, which can be a challenge given that the quality of the underlying property web sites in each country are sometimes pretty questionable.

2.  AltSearchEngines has come across seven significant Property Search Engines in your area, and other minor ones. Why such a crowded field? Are you all primarily similar, or fundamentally different?

In the past few years I’ve seen lots of projects in this area, probably motivated by the promise of easy money: just combine real estate (money!) with the Google business model (more money!) with the mashup/search engine template (easy!). So there was economic motivation and a low perceived entry barrier. If anything, I’m surprised there haven’t been many more startups in the field…maybe what’s missing in the mix is some social networking (sexy!)

Vertical search is a good, simple yet intuitive idea that no one was doing it Europe. That companies like News Corp, The New York Times and Sequoia have invested in similar products in the US (and now in Europe) further encourages European entrepreneurs to start similar local projects before the Americans arrive. As for differences among vertical search engines, it all depends on how closely you look. On some level, Google and Yahoo both have search engines, but they are not regarded as the same. Similarly, on a very basic level, we’re all search engines focused on property. But many of us operate in different markets. For example, Globrix is not currently nuroa’s direct competitor. Their market is the UK, and their main competition is in the UK — nuroa is focused currently on Germany and Spain. Each market is a different world with its own rules, home-buying and renting patterns, economic evolution, language, competitors and targets.

Apart from geography, some of us have different objectives. nuroa aims to be profoundly local — Spaniards buying properties in Spain, and Germans buying properties in Germany — whereas Properazzi has a much more international focus and scope from the beginning. On a technical level, we sometimes differ on how we obtain the property ads. Some of us rely more on receiving XML feeds, whereas others focus more on search technology. Then as an empirical matter, there are obviously going to be differences in whose results are more precise and exhaustive with a higher degree of recall, and the breadth and quality of the results will probably be the key differentiator from the consumer’s point of view. And finally, there are “softer” issues like usability and design that also affect the user experience. That being said, I’m pretty sure that we all borrow and learn from one another.

3.  Most of the updates that we receive from your space are larger territories covered, which is natural, but where does it end for you? How much geography do you seek to cover in the end?

The world, of course! Properazzi never made any secret of its ambition to be the platform for the world’s property listings. Since launching in March 2007, Properazzi have been steadily adding new markets, and now cover 50 countries. We’ll continue to add support for further countries in 2008. But geography is not the only axis along which Properazzi are planning to expand near term.

To date, the web 1.0 real estate portals have been quite successful even though they only operate in one geographical market (this goes back to my answer above about whether those of us who currently operate in different markets will necessarily have to compete against one other at some later point). Rightmove’s expansion plan is to cover all of the UK as opposed to just the big cities like London.

For the moment, they’ve felt no need to compete vigorously outside of the UK. Seloger has a similar strategy to increase its penetration in the provinces outside of Paris. As mentioned above, Rightmove has a market cap of more than €1 billion, and Seloger is close with a market cap of more than €700 million. So you can create an interesting business in just one geographical market if you can become the market leader. That being said, our search technology in nuroa is obviously very scalable, so you can easily adapt it to new countries and even to new verticals. As with most things, your limits will depend to some extent on your financing and your ability to execute.

4.  Can you just summarize your business model and how it relates to the financial needs of the real estate agents/brokers, and perhaps even the property searchers and/or sellers?

Our business model is advertising. It’s great for the advertisers because we’re delivering a very high-value audience for much lower cost than they’re used to paying. For property buyers/renters, Properazzi is 100% free, so our model works great for them as well.

We make money via advertising — featured listings, banners, etc. The web 1.0 real estate portals require real estate agents/brokers to pay a set monthly fee to upload a predetermined number of listings regardless of whether the site actually generates leads for the real estate agency. And given that most of these portals only intend to grow within their national boundaries (and some are public companies), the only ways for them to grow are up and out — up, meaning that they will have to raise prices as many have done over the past year, in some cases doubling the prices; and out, meaning out of the big cities where they started and into the more remote provinces within their geographic market.

Nuroa’s model is different — more pay per click than subscription fee: an agency only pays if we send them traffic for a featured listing or some other form of sponsored ad/banner. Agents don’t have to pay us to have their listings show up organically on our site. From the consumers’ perspective, it’s very useful to have all or most of the property ads in nuroa. Classifieds sites are growing like mushrooms as print continues to falter and more traditional media companies move online, and no one has the time or attention span to visit 50 sites to look for her perfect property. A property search engine cuts out all of the unnecessary steps and let’s the user find her dream home in a couple of clicks.

5.  What is your relationship to the major search engines, Google, Yahoo!, et al? Are they your major concern – or are your fellow Property search engines your main rivals for business?

I honestly think it’s too early days to answer this question effectively. As we evolve, it’s just not clear yet who ends up being a partner, a competitor, or simply a “not relevant”. Ask me again in two or three years :)

Our goal is to supplement not supplant Google and the other major search engines. We don’t really see them as our competition. Google had Google Base for a while, but they don’t really seem to have pushed it very hard. And last year TechCrunch reported that Google was in talks to buy SimplyHired, so obviously that means that, if the reports are true, Google sees the opportunity in vertical search and isn’t opposed to purchasing the market-leader in each vertical. That being said, we didn’t start this company hoping to be bought by Google. Not that we’d be opposed to it on principle, but nuroa’s goal is to become the next Rightmove or the next Seloger. And we see our fellow property search engines within our geographical markets as our most immediate competitors.

6.  How do you market your site – drive users to you as opposed to anywhere else?

We dabble in most of the usual marketing type of activities, but work hardest on developing a great product for users so they can remember and return to our site, and recommend it to their friends.

As mentioned above, this is our main challenge. And we take a variety of approaches to marketing our product, though I’d probably prefer not to explain our strategic marketing plan in any great amount of detail. But I can say that it’s a combination of SEO, SEM and viral marketing.

7.  It’s a tradition to say something complimentary about your debate partner.

Migoa: nice integration of flickr and technorati data, and they chose a great city in which to be based.

In the case of Properazzi, I’d say that we learned a lot from them. They launched before we did and provided a key test case for seeing the market’s reaction and adapting our own strategy before launching. They were also the first European vertical search engine to receive funding from a major European VC, so that served as an inspiration to us. 

笑い Warai! Blogdimension launches in Japanese!

The Japanese version of Blogdimension.com – the Web 2.0 Search Engine – allows Japanese speaking users to search for contents in their own language. Be they Japanese natives, students, business people or simply lovers of the great Japanese tongue and culture.

They can now find easily all kind of Japanese Web 2.0 sources ie. blogs, microblogs (Twitter, Tumblr, Jaiku…), forums, online news, images, audio files & podcasts, online videos…

All these contents can now be searched directly from a Japanese interface within Blogdimension.com.  No need to mention that the Japanese language is one among the first blogging languages. Sometimes even the first one (see David Sifry’s analysis).

Blogdimension has been accumulating tons of Japanese Web 2.0 sources since last summer’s relaunch. It was logical to offer Japanese users a way to search for all these contents.

So, dear Japanese users, should you find any interesting Web 2.0 link, a blog, or whatever containing a RSS or Atom feed, please do submit it so you help us to increase the index of Japanese sources.

We wish you a pleasant journey in Blogdimension Japan and of course a lot of fun in your Web 2.0 search experience.

笑い Warai!

Alternative Search Engines & the Subjective Web

January 15th, 2008 by Charles S. Knight
Posted in Guest Authors | No Comments »

The history of Internet led us through roughly 6 different stages reflected by the contents found in the World Wide Web:

* 1993-1995: most of the content to be found in the Web was from universitarian and scientific origin,
* 1995-1997: then came the era of personal webpages indexed by the first portals and search engines,
* 1997-1999: corporate websites and webmerchants started to flourish,
* 1999-2001: press media went totally online. Other media (TV, radio) were condemned to stay off-line because of the weakness of the bandwidth!

Then came a technological leap: broadband…

* 2001-2006: during this period the Web became suddenly richer (rich media) and more participative allowing multimedia files to be delivered and exchanged online. Blogs appeared, MP3 music systems like Napster paved the way with Peer-to-Peer systems. Immediately followed by video online sharing systems and voice over the net. The Web 2.0 was born making it possible for everyone to become a consumer and a producer of the content.
* 2007: this date is crucial since it marks the upcoming of virtual life and mobile and Internet convergence.

Gigantic and incumbent search engines like Google, Yahoo or MSN due to their longevity encompassed all these periods and therefore succeeded in indexing all kind of contents in their databases.

This enormous accumulation of content by the leading search systems during the web evolution can be considered as an asset in regard with the vast choice of sources offered to the users.

But it is not really! Historical search systems are overwhelmed by too much “noise” content making it difficult to find straightforward relevant content. Their links databases are spoiled with too many obsolete and commercial content making it hard to bring satisfaction to the users.

Moreover, the fact that their ranking models are all based on popularity (sometimes dubbed as “authority”) makes their indices not very dynamical. Popular web sources are almost on top and new sources have to struggle in order to get to the the first results pages.

It is not a lie to say that if the users use only one search engine they miss much of the reality of today’s web.

Things must now change as the users become more aware! The users should consider specializing their search operations.

To do this, a new generation of search engines is emerging on the market. These niche search engines are the “alternative search engines”.

Each alternative system has its own speciality and positionning. Some are dedicated to the retrieval of images, other to blogs, still others to given topics and type of content. Some of them carry out this task in an extremely creative way thanks to smart interfaces enhanced by the Ajax language. Some are real AI tools.

If you wish to discover all the richness of the alternative search engines, we invite you to read the excellent www.altsearchengines.com, a blog from the ReadWriteWeb network specially dedicated to these new generation search engines. This blog is thoroughly animated and sourced by Charles Knight who scans the whole Internet on a daily basis to find and present new alternative search engines.

www.blogdimension.com also belongs to this breed of alternative search engines. It proposes a totally new way of addressing the usage of online search activities.

Blogdimension focuses exclusively on Web 2.0 content like blogs, microblogs, forums, online media, images derived from these sources, audio files & podcasts, videos. Generally speaking, Blogdimension retrieves syndicated (RSS) and user generated content only. In the contrary of all the big ones, Blogdimension.com does not give access to any general, encyclopedic or commercial web eventhough one can find such content also in our search engine incidentally.

By such a positionning, Blogdimension appears as a complementary tool to the incumbent search engines represented by the trio Google-Yahoo-MSN (Live.com). Blogdimension exists in English, French, Spanish, Chinese and soon in Japanese, Portuguese and Russian. Other great languages are in progress.

Said in a different way, Blogdimension gives access to the subjective part of the web. To the web made of opinions and viewpoints (blogs, forums, videos). This viral and unconventional part of the web which expresses individual thoughts, anger and passion. In other words the free web!

It is time to use several search engines to discover the still new unexplored dimensions of the World Wide Web!

Search Engine SenseBot Goes Vertical!

January 15th, 2008 by Charles S. Knight
Posted in Alts, Reviews, Updates | No Comments »



In which SenseBot releases tools to build a summary of Web pages selected by users.

In its generic version, SenseBot summarizes Web pages from the first page of results returned by either Google or Yahoo or Live. The search results on the first page are supposed to be the most relevant ones, representing the subject of the user’s query from across the Web. The idea behind SenseBot is to serve a text summary of these top results, providing a quick grasp on the topic of the query and sometimes obviating the need for the user to drill down into individual sources.

The latest update to SenseBot is intended to apply the same technology to various vertical areas. The advantage of going in this direction is that in a vertical space, the user intent can usually be better understood, and the set of Web pages is narrowed down. This allows to produce summaries of higher quality than on a generic search engine’s results.

There are two new tools:

A Web page interface allowing the user to enter a query and the URLs of pages to be summarized. A summary of the specified pages is produced.

An XML Web service allowing an external client application to pass a query and a set of URLs to SenseBot, and receive a summary as its output.

The tools are intended for companies that want to assess the applicability of SenseBot technology to their particular domain of knowledge or interest. We extend a special welcome to vertical alternative search engines, sharing Charles Knight’s vision of alts teaming together to create a viable alternative to major search engines.  Some of the verticals we think can particularly benefit from our approach are: financial news and research; medical information; legal information; competitive intelligence; education; libraries; etc.

At AltSearchEngines, we are often approached by search engines that we feel are “not ready for Prime Time.”  FuzzFind had me stumped, so I asked “Mark” what he thought.  “Post it,” he said.  Who’s right?

FuzzFind is a web search mashup that combines the power of the leading search engines and social bookmarking sites to make it easier for you to locate and identify the most relevant information. All results are grouped together and sorted according to the search engine rankings plus the popularity of the sites according to the social bookmarking community.

Give it a try and compare the results that you get with your favourite search engines. Comments?
