If clients need to visit you, is your home business easy to find? How will you cater for clients with disabilities? If you live in a busy street, you may have to provide off-street parking at your home - contact your local council for more information. If you don't have the space to meet with clients, you could use coffee shops, libraries or even rented meeting rooms.
These pay-per-click ads appear on your blog. Every time somebody clicks on an ad (which is supposed to be about a subject related to your niche), you make a few cents or more. Small amounts each time, but it adds up. This is extremely hands-off. You just need to get a code from Google, place it on your website - and the ads will automatically appear on your blog. Google will only show ads that are relevant to your blog so it's a good experience for your visitors and maximizes the amount of clicks you get, meaning more income.
