If you thought you could make money online without declaring it to the taxman, think again.

Austria, Denmark, Britain, Canada, The Netherlands and Sweden have teamed up for the “Xenon” program, which was started in The Netherlands in 2004 by the Dutch equivalent of the IRS, Belastingdienst.

Wired Digital reports, “Xenon is primarily a spider: a program that downloads a web page, then traverses its links and downloads those as well, ad infinitum. In this manner spiders can create huge datasets of web material, while preserving the relationships between pages at the moment they were spidered — something that can reveal a lot about the people that made the pages.”

The program aims to crack down on suspected internet tax cheats, using a sophisticated web crawling program to monitor transactions on auction sites, and track operators of online shops, poker and porn sites.

Once the web pages are screen-scraped, Xenon’s Identity Information Extraction Module interfaces with national databases containing information like street and city names. It uses that data to automatically identify mailing addresses and other identity information present on the websites it has crawled, which it puts into a database that can be matched in bulk with national tax records.

Canada’s tax authorities declined to state what its Xenon data retention policies are, as did Simon Bird, head of the “Web Robot Team” at the British HM Revenue and Customs office.

In the United States, the IRS is not a part of the Xenon project, but would neither confirm nor deny that it uses spidering software in its investigations.

How to create that online money-spinner that works automatically, even when you sleep, is a question often asked.

One solution — rather an old one, it has to be said — is affiliate marketing. Essentially, this is signing up as an affiliate with a website selling products off its site. When anyone clicks over from your site and purchases the product, a “cookie” (a little scrap of software identifying you) registers a percentage of the price paid. This may vary from 4pc on the Amazon Associates scheme, to a bumper 50pc for selling an eproduct, like an ebook or ecourse.

Quite often you’ll find an “Affiliates” link in the footer on retail and other websites. An alternative is to use a mass afilliation scheme like Commission Junction or Tradedoubler, where you can choose from a large range of schemes from crafts to credit cards.

So long as the product or service matches the subject of your site, you should be able to make a start.

Many of the early Internet marketers started out on affiliate schemes. Some became millionaires quite quickly, by first doing well, then selling their own ebooks on how they did it.

The secret is to presell the product on your site before the client clicks through to the seller’s site. That way they are much more inclined to buy.

From there, it’s a numbers game. The more traffic your site generates, the more likely you are to get sales. That early lesson made serious affiliate marketers become experts in SEO — search-engine optimization — whereby the site figures prominently in Google and other search results for certain keywords.

An understanding of the keywords searched for for each product is also necessary to do well from this process. There are keyword aids available free on the net.

Affiliate marketing can be tough if you go about it the wrong way. But with hard work and a shrewd eye for a chance, you could do very well at it.

People make whole careers out of advising on how to get websites to feature prominently on search engines such as Google. The process is called search engine optimisation, but it doesn’t need to be complicated.

Duncan Jennings started his first website when he was 17. At 24, now owns www.econversions.com. He says :

“All websites want to appear at the top of the list when someone searches on Google. In response to a search, Google will take all the websites that are relevant and rank them according to the number and quality of other sites that have linked to them. If you can get links to your site on lots of others, you will be ranked higher and you will get more traffic. It builds from there.”

All of the above are from the Mail Group of newspapers.

The UK Mail on Sunday has five top share tips for British investors.

Pointing out that 2006 was a much better year than predicted, the runes say that the coming 12 months will be “rocky”. However, we’re assured that the following stocks will perform well whatever the state of the markets :

1. Barclays : This is one of the world’s top banks with a strong High Street network of retail branches, as well a top flight investment bank. It also boasts a very successful fund management division with fast-growing international business interests. Its shares are rising because it has become the subject of a number of takeover attempts in recent times.

2. Biffa : This company collects, treats and recycles rubbish (garbage) for 80,000 customers worldwide. Biffa has been quoted on the London Stock Exchange since October 2006. Prior to its IPO it was part of Severn Trent Water company. The sector is a buoyant one and, it’s believed, Biffa’s management team will make the most of it.

3. Halfords : While the retail sector is expected to be flaky for most businesses, Halfords may well be the exception. It’s the largest seller of car and bycycle parts in the UK and has benefited from a raft of safety legislation in recent years. Analysts expect it to perform well in 2007.

4. CONCATENO : This company is involved in testing for drugs and alcohol — a growing service across the board — advising companies from building to shipping. It works with a number of public sector bodies. It is expected to come into its own this year and trades on the AIM (Alternative Investment Market).

5. Afren : Afren is an oil and gas exploration company run by a former head of OPEC. Its mission is in Africa and is seen as helping rather than exploiting local resources. Many experts think its time has come and it should rise well above its 57p share price in the year ahead.
