How Google Promotes Chrome

Is Chrome the most heavily promoted Google product? Like for many other products, Google "buys" AdWords ads to promote Chrome, but there are many other places where you can find Chrome ads.


When it was launched, Google placed a link on the homepage which stayed there for a week. At the same time, Chrome gained a prominent placement on Google Japan's homepage, next to services like YouTube or Gmail:

Starting from today, YouTube promotes Chrome on the homepage and the bottom of every page:


The promotion is similar to the last month's ad from orkut (screenshot licensed as Creative Commons):


If you download Chrome from one of these sites, Google will append a RLZ parameter to each Google search URL. "RLZ contains some encoded information, such as where you downloaded Google Chrome and where you got it from. This parameter does not uniquely identify you, nor is it used to target advertising. This information is used to understand the effectiveness of different distribution mechanisms, such as downloads directly from Google vs. other distribution channels," explains Chromium Blog.

It's unclear whether Google "will do well to expand its business", but Chrome seems to be a part of a strategic initiative to make Google more visible on the desktop, a mix between Google Toolbar, Google Desktop and Gears that turned into a browser and that needs a critical mass to be taken seriously.

Google Uses OCR to Index Scanned PDF Files

Google started to index to full text of "scanned" PDF files using a technique called OCR (optical character recognition). "Every day, people all over the world post scanned documents online -- everything from official government reports to obscure academic papers. These files usually contain images of text, rather than the text themselves. But all of these documents have one thing in common: someone somewhere thought they were they were valuable enough to share with the world," says Evin Levey.

The great thing about the new feature is that you won't notice it unless you look for it, but it improves the quality of Google's search results. Google doesn't mention how many of the 300 million indexed PDF files were converted into text, but you can see some examples if you search for: [repairing aluminium wiring], [Steady success in a volatile world] and click on "View as HTML".


Google sponsors an open-source OCR software called OCRopus and it's likely that Google used it for indexing PDF files from the web. "OCRopus is a state-of-the-art document analysis and OCR system, featuring pluggable layout analysis, pluggable character recognition, statistical natural language modeling, and multi-lingual capabilities. (...) It's initially intended for high-throughput, high-volume document conversion efforts. We expect that it will also be an excellent OCR system for many other applications."
