Adwords Bid Strategy Best Learning

1. => Cost Per Click (CPC): - CPC is the most you'll typically be charged for a click, but you'll often be charged less -- sometimes much less. That final amount you're charged for a click is called your actual CPC. If you enter a max. CPC bid and someone clicks your ad, that click won't cost you more than the maximum CPC bid amount that you set.
#CPC = Total Cost of Click/Total no of Click

2. => Cost Per Lead (CPL): Reduce Your Cost Per Click (CPC) Every time a searcher clicks on your ad, a portion of your marketing dollars is spent. ... Cost Per Click (CPC) and conversion rate (CR) are both instrumental in determining your CPL, therefore when CPC is reduced, so is CPL- assuming conversion rate is constant.
#CPL = Total Lead/Total Cost Spend

3. => Cost Per View: Cost Per View (CPV) bidding is the default way to set the amount you'll pay for TrueView video ads in Google Ads. With CPV bidding, you'll pay for video views or interactions (such as clicks on call-to-action overlays, cards, and companion banners).

4. => Cost Per Action (CPA): CPA bidding is a method of paid advertising that allows you to tightly control your advertising spend. Rather than paying Google for every time someone clicks on one of your ads (as with CPC bidding), CPA bidding only requires you to pay for each conversion, a metric you define yourself when you set up each campaign.
#CPA = Total Cost/Total Number of Leads

5. => Cost-per-thousand impressions (CPM): A way to bid where you pay per one thousand views (impressions) on the Google Display Network. Viewable CPM bidding ensures that you only pay when your ads can be seen.

6. => Average CTR (or average click-through rate) is the ratio of ad clicks to impressions in your AdWords campaigns. While basic CTR measures the rate of clicks on each ad, average CTR calculates the amount of clicks vs. impressions across your campaign, or for each individual keyword.
#CTR = Total Click/Total No of Impressions

7. => (ROAS)In general ROAS is Return On Advertising Spend. ROAS helps you to see if the advertising budget is generating sufficient revenue. In AdWords, Target ROAS is one of the automated bidding strategies.
#ROAS = Revenue Earned From Advertising / Advertising Expense

8. => Enhanced CPC (ECPC): Definition. A bid strategy that adjusts your cost-per-click (CPC) to help maximize conversions. ECPC combines manual bidding with a Smart Bidding strategy, like Target CPA or Target ROAS. ... ECPC can be tested along with third-party bidding systems to give you a limited degree of Smart Bidding.
