Welcome to the Q&A Forum

I have been using WIX for my website www.siimajackets.com.

Some of my keywords are currently ranking in top 5 in UK. I am an SEO my self.

You will eventually rank but it will take time just like with any other platform.

When i did the website i didnt know much about SEO. Now i know but i am still with wix since i invested a lot on their platform. I can't say i am dissappointed. The website is good. Speed is very good both on mobile and desktop. Rankings are getting higher.

There are so many things to consider in order for your page to rank high. The platform is one of them but it will not restrict you from ranking in page one of google.

Let me know if you need any help.

The three numbers would be:

1. Conversion value - whether this be the value passed from eCommerce tracking or assigned values for completed actions that have been nominated.  Without tracking a value or assigning any value it becomes difficult to effectively measure performance at a keyword level.  Every account must have measures of success.
2. Conv. value / cost - are you receiving more than what you are paying per click.  Once you assign a value for margin you should be able to adjust CPC easily based on the return you are getting back
3. CTR - what % of the market are you winning, once your keywords have passed the profitability test the main goal should be to increase CTR and subsequently improve quality score which will decrease CPC's.

Following these rules should ensure most profitable keywords are focused on to increase ROI and campaign performance.

I would run within the same campaign.  If you create separate ads and site links for mobile devices it should make tracking performance fairly easy.  The main difficulty in running separate campaigns would be having the same keywords appearing on desktop and potentially competing.
