Last year, Google announced Caffeine project to improve on web page indexing, accuracy and comprehensiveness of results and now, Caffeine is ready to be rolled out.

Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.

With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally. As we find new pages, or new information on existing pages, we can add these straight to the index. That means you can find fresher information than ever before—no matter when or where it was published.

Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles.


Google's new Caffeine search index will crawl the Web more frequently and in smaller bites in hopes of amassing Web content more quickly and comprehensively than before.

The new indexing system, dubbed "Caffeine", will provide the largest selection of web content ever offered on Google. It's faster - processing hundreds of thousands of pages in parallel every second - and takes up nearly 100 million gigabytes of storage in one database.

But, as happens with so many tweaks to Google's mysterious formula, some businesses and websites that rely heavily on Google referrals might see their traffic suffer as the changes could result in them falling further down the search rankings.


We moved the goalposts over here ... Google senior vice-president Alan Eustace describes the changes as "huge".

In a world exclusive interview before today's announcement of the update, Google fellow and 20-year search veteran Amit Singhal said that, while there might be some losers, the primary goal was to improve the user experience.
"As the web is moving forward, freshness is becoming critical and we have worked a lot on this. Starting tomorrow, our users will see 70 per cent fresher results in Google's search results," he said.

"In our world, users come first and, with Caffeine, we will observe our user search experience getting much better, much fresher."

The company dominates the online search business worldwide. Although Microsoft's Bing has made inroads in some markets, Google still has more than 90 per cent of the share of searches in Australia - 87.8 per cent through the google.com.au address and 5 per cent through google.com.

Bing has captured 3.2 per cent of Australian searches in its first year since launch, according to Hitwise's June 5 figures.

Singhal explained that the 70 per cent improvement figure was derived by measuring the "average age" of results across search queries and comparing it with that of the previous algorithm.

Word of Caffeine leaked last year when Google switched it on for a limited number of beta testers but from today it will be rolled out across all of its data centres.
Search engine optimisation (SEO) gurus have been working frantically to figure out the new system and how best to game it to their advantage.

Matt Cutts Explains Caffeine Update

Just as there are different ways of writing for novels, for advertising and for films, there is a way to write for the Internet. To find content on the web we use search engines. To make sure the search engines find our content we optimize it. Search Engine Optimization (SEO) copywriting is writing content that the reader wants to read and will be easily found and rank well with search engines.

The object of writing for the Internet is to get the reader to use your content to click through to your website. If they don't get to your website, they can't look at your products or services and you will have lost a potential customer. Here are a few mistakes that you'll want to avoid.



#1 - Hackneyed headline

This is a extremely important mistake not to make. If they don't even look at your article, all your time and attempt are wasted. If you provide an attention grabbing title, one that makes them curious enough to open your article, you're halfway there.

Here are just a few thoughts to get you thinking: Use titles that describe the content of your article but are short and brief; Use keywords in your title that people might be searching for; People can't resist articles with lists or tips such as, "Top 10 Copywriting Mistakes" or "Top Tips on Getting Your Articles Read"; and "How to" articles are popular as well.

The base line here is to put some thought into your title. Think about how to get a reader's consideration.



#2 - Create tasteless body Content

Start to end - try to keep it attractive. Make reading your article a enjoyable experience for your reader. Here are a few suggestions.

Make it amusing, relevant and grammatically correct. Nothing pulls the reader out of a story more than bad grammar and misspelled words.

Use short sentences and try to limit paragraphs to two or three lines. Concentrate on writing rich and proper copy rather than just practical words.

Have a sense of funniness. This gives your articles personality. Don't give a sales pitch - use a call to action. The reason of your article is to get your reader to get to your website. Your writing could include a reason for them to find more information, either from another article that you've written or from your website.

"Content is king". If you keep this in mind, you'll be ahead of the game. Search engines love well-written and constructive content. So do readers.



#3 – Create a difficult to read content with illusive context

Reader ought to be able to easily scan your article and find headings that will tell them what the section is about. You can use numbered lists and bullets to systematize your ideas so they are quickly read. If you italicize, bold or underline a word, the search engine, take for granted that it's a keyword. You can use this to your advantage. Conversely, if you make use of these tags a lot or if you use them on non-keywords, you'll puzzle the search engines and misplace any benefit you would have gained.

The other thing that makes a page easy to scan is small paragraphs. When you look at your copy on the page, you should see a lot of white space. Looking at a page that's entirely filled with words is intimidating to a reader. You want to make it as friendly and welcoming and as easy to read as possible.



#4 - Misuse Keywords

Here remain a few suggestions regarding keywords:
• Target a set of keywords in each post but don't use them more than three or four times on a page. If you use the equal keywords again and again, search engines can tell that the article isn't very practical.

• Use a wide range of words that relate to your topic.

• Use synonyms of your keywords in count to the keywords.

• Don't stick to a typical keyword density for every article. You want your words to flow logically, and do to excess of keywords makes your copy sound forced.

• Review your keywords every so often. Sometimes your business changes and you desire your articles to alter also.

If you offer your reader with content that lets them learn or experience something, you'll have a contented reader. If you provide the search engines with high-quality keywords and a selection of them, you'll have a happy search engine.



#5 - Attempt to trap the popular Search Engines

Practicing doubtful tactics like cloaking and using unseen text is not prudent. The last thing you fancy is to get your site banned. These kinds of tricks will do it. So can using hidden links, link farms, linking to bad sites, distributing viruses and sending spam. Don't try to trick the search engines and don't work with any companies that use these techniques.

Overcoming these common mistakes can give you head start when creating effectual content on the Internet. SEO copywriting requires effort. Putting content a site and distributing it on the web takes time. If you effort at it over time and create lots of valuable content, successfully "brandcasting" your site, you'll be satisfied with more traffic.
