Within your terms and conditions, you need to define what can and cannot be promoted through PPC. The most obvious restrictions are brand terms and misspellings. So one of your objectives could be to increase your visibility on search engine affiliates, and you can do this by targeting only long tail keywords. Other things to consider are whether affiliates can link PPC directly to your site and whether they can use your URL in the ad copy. These are decisions you need to state in your terms and conditions.
Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
