Measuring SEM campaign performance


Important KPI’s in SEM campaign

There are many interesting statistics in search engine marketing (SEM). Some examples include:

  • Conversion rate: This is the percentage of users who complete a desired action (such as making a purchase or filling out a form) after clicking on a search ad. A high conversion rate is generally seen as a good sign that the ad is effective and relevant to the user.
  • Cost per click (CPC): This is the amount that an advertiser pays each time someone clicks on one of their ads. A low CPC can indicate that the ad is performing well and attracting a lot of clicks without costing the advertiser too much money.
  • Click-through rate (CTR): This is the percentage of users who click on an ad after seeing it. A high CTR can indicate that the ad is well-targeted and relevant to the user, while a low CTR may indicate that the ad is not resonating with its intended audience.
  • Quality Score: This is a score assigned by search engines to ads based on their relevance and the quality of the landing page they lead to. A high Quality Score can lead to lower CPCs and better ad placement.
  • Return on investment (ROI): This is a measure of how much money an advertiser makes in relation to how much they spend on SEM. A high ROI can indicate that the advertiser’s SEM efforts are paying off, while a low ROI may indicate that the campaign is not performing as well as expected.

How to calculate SEM ROI?

To calculate the return on investment (ROI) for a search engine marketing (SEM) campaign, you can use the following formula:

ROI = (Revenue – Cost) / Cost

Here’s what each of these terms means:

  • Revenue: This is the total amount of money that the SEM campaign has generated, either through sales or other desired actions (such as form submissions or phone calls).
  • Cost: This is the total amount of money that has been spent on the SEM campaign, including the cost of the ads and any related fees (such as management fees or tracking fees).

To use the formula, simply substitute in the relevant numbers for revenue and cost. For example, if your SEM campaign generated $1000 in revenue and cost $500 to run, your ROI would be:

ROI = ($1000 – $500) / $500 ROI = 1

This means that the campaign had an ROI of 100%.

It’s important to note that ROI is just one way to measure the success of an SEM campaign, and there are many other factors that can contribute to its overall effectiveness.
