Lenses are little pages of information that can be straight to the point and contain links to items that when sold can provide an income.
The term 'lens' means a 'view finder' and that's what it's all about.
There are many opportunities to express one's views through blogs or in dedicated communities that provide free hosting and helpful suggestions.
One can also do it in forums.
Such sites are possibly already geared up to add affiliate links with resources for readers to click on and for publishers to share the rewards.
The main thing to bear in mind is not to make a sales site full of commercials.
People are looking for information and when that is provided in a proper manner they will be more inclined to look at what you are offering.
For instance, if you are providing links to bread makers then you need to state why you are an expert in them and how long you have used one for.
It is also important to give the other side to the story.
If you have heard of other items that you have not used and want to suggest someone buys it then search out the right information and be responsible for what you write.
Many lenses are not about selling stuff as they are simply information only sites.
This suites people who have a lot of knowledge and want to share it around without writing it into books.
That's what makes the Internet so fascinating for searches for ideas and recipes and things.
Many folk like to talk and they can do that in a lens whereby they are simply speaking out to an audience about something they love, whether it's their garden, their hobby or their family.
Whatever the need is building a lens and expressing oneself is a great way to get onto the Internet, make friends and become involved in the fastest growing trend of the 21st Century.
