What is the best day to shop online?

When is the best time to shop online? The best time to shop online depends on your target market. If you are targeting people who work 9-5 jobs, then Tuesday and Thursday would be a good day to advertise. However, if you're trying to target students and young adults, then Wednesday and Friday would be better days for advertising.

The best time to advertise also depends on the type of product you are selling. If you're selling a physical product, then the best time to advertise would be during the day. However, if you're selling an online course or information product, then the best time to advertise would be at night.

Here are some statistics that show the best times to advertise:

- Sunday is the worst day of the week to advertise.

- Wednesday and Friday are the best days of the week to advertise .

- Saturday is the best day of the week to advertise if you're selling a physical product.

- Sunday and Monday are the best days of the week to advertise if you're selling an information product.

So, when should you be advertising?

Well, you can use the above statistics to help you decide.

- If you're selling a physical product, it's best to advertise on Saturday and Sunday.

- If you're selling an information product, it's best to advertise on Monday and Tuesday.

- If you're selling a service, it's best to advertise on Wednesday and Thursday.

Now, the above statistics are just averages. The best time to advertise will vary depending on your niche. If you have a very specific niche, you can find out when your target audience is online.

So, for example, if you're selling information about the history of video games, you might want to advertise on a Monday and Tuesday. However, if you're selling information about how to start a home business, you might want to advertise on a Friday and Saturday.

So, where do you find out when your target audience is online? You can use Google's free keyword planner tool . This will tell you how many people are searching for a particular keyword in a given month.

The next step is to find out how much you can expect to pay for each click on your ad. You can do this by using Google's Adwords tool. This will tell you how much each click on your ad will cost.

The final step is to decide how much you are willing to pay for a click on your ad. You can do this by dividing the amount of money you want to spend by the number of clicks you expect to get.

The results of this calculation will tell you how much you can afford to pay for each click on your ad. If the price is too high, then you may need to reconsider your target audience or adjust your budget.
