create a correct shopping ad, so that it display at the centre of the shopping page.

Dear sir / madam,
I need to enable my shopping ad to display ad in centre rather than at the top or bottom of the google shopping page.

Requiremnet: since this google ad account contains a lot of sensitive information, therefore I require to send me instruction only, without login my google ad account.

Here is how my existing shopping ad created (Option 1) as attached with filename google-web-site-traffic-shopping-campaign.jpg
1. Create campaign
2. choose New Campaign
3. Website Traffic (see attachment)
4. Select Shopping

Option 2: I found another there is a Sales button also lead to Shopping, (please refer to attachment as well), with filename google-Sales-shopping-campaign.jpg

Option 3: I also found another option can lead to creating a shopping ad, with filename: google-Leads-shopping-campaign.jpg

Which one should I use to create a shopping ad so that it can be display at the centre of the Shopping page? Currently my shopping ads were created using Option 1.

payment will be paid when the instructions I followed works and correct.
