the most important ga4 metrics for smarter advertising decisions

google analytics 4 also called ga4 is the new way to track how people use websites and apps its different from the old version which was called universal analytics and now everyone is supposed to move to ga4 because the old one  is not going to work anymore

if you are working in a social media marketing agency or running ads for any kind of business you need to understand ga4 because it shows what is  happening on the website after people click on your ad

this article will help explain what are the most important ga4 metrics for smarter advertising and how a good marketing agency can use these to  make better decisions


why ga4 is different than old analytics

before at universal analytics we used to track things like bounce rate and sessions and goals and pages per session but ga4 changed many of these and now we track events so everything in ga4 is based on events like a page view is an event a click is an event a scroll is an event even watching a video or buying something is an event this means we  can understand more details and track more things but also it can be confusing at first but for  social media marketing agency it is super useful because now you can see exactly what people are doing after clicking ads on instagram facebook tiktok or google


important ga4 metric 1 engagement rate

so before we have bounce rate and that was like when someone opened a page and left quickly without doing anything but ga4 changed this and now it shows engagement rate engagement rate is when someone spends at least 10 seconds on the page or does something like clicks or scrolls this metric helps a marketing agency know if the ad is sending people to a good page or if people are just not interested if engagement rate is high that means people like the page and are maybe thinking to buy something or read more if it is low then maybe the ad is not matching the page or the page was boring or slow


important ga4 metric 2 engaged sessions per user

this one shows how many times each user did something useful on the site like scrolling or clicking or watching a video a social media marketing agency can use this to check if their ad campaign is getting real attention or just random visits for example if you run ads for a fashion store and you get a lot of visitors but very low engaged sessions per user then maybe people are just looking and not buying or not liking the site a good marketing agency will see this number and test different ad types or change the landing page to improve  it


important ga4 metric 3 average engagement time

this shows how long people are really active on the site not just how long the tab was open but how long they were scrolling clicking or doing something if someone opens the site and goes to make coffee and comes back that time will not count so this is more real than the old time on page this metric is good for all kinds of ads not just social media because it shows if the content is keeping people focused a smart social media marketing agency will check this and try to create more content that holds attention like maybe longer videos or useful blogs or product demos


important ga4 metric 4 event count

event count is how many events happened on the site and this is like clicks form submits video views add to cart and more you can also set custom events in ga4 for example when someone downloads a file or signs up to newsletter or uses the search box so if a marketing agency is doing a campaign for a lead generation business they can track how many people fill the form and where they came from event count helps you see what actions are happening and which ads are really working not just getting views


important ga4 metric 5 conversions

so conversion is still a big thing in ga4 but now it is more flexible before we had to set goals and it was not so easy but now any event can be marked as a conversion like form submit or add to cart or buy this helps marketing agencies in egypt and other places to track any kind of success that fits the client you can even track different conversions for different campaigns like one for signups and one for purchases a social media marketing agency should always have clear conversion setup before running ads so they can report real results not just traffic


important ga4 metric 6 traffic source and medium

knowing where people come from is always important and ga4 still shows this you can see if someone came from google search or facebook or instagram or email or directly but also ga4 shows campaign details like if the click came from a certain ad with a special name this helps a marketing agency in egypt compare all the channels and see which one gives better traffic or more sales sometimes you may find that google ads bring more traffic but instagram ads bring more engaged users and you can change the budget based on that


important ga4 metric 7 demographics and tech info

ga4 also shows user info like age gender location language device and more so a social media marketing agency can see if the campaign is reaching the right people like if you sell baby clothes and most visitors are men age 18 to 24 maybe something is wrong with targeting also device info helps you check if most people are using phone or desktop and maybe you need to fix mobile site or test mobile ads more


role of a marketing agency in setting up ga4

ga4 is very useful but setup is not easy for beginner so a smart marketing agency in egypt can help you do it right from the start they will install the code correctly and set up the events that match your business goals for example for ecommerce they will track add to cart begin checkout purchase for services they will track contact form or quote request or click to call this makes reporting better and decisions smarter also they can connect ga4 to google ads or bigquery or other tools to make dashboards or send data to other places


how ga4 helps with ad testing

one cool thing is that ga4 helps you test different ads and landing pages and see what works best for example if a social media marketing agency runs two facebook ad sets with different images and both go to different versions of the page you can use ga4 to see which version got more engaged users and more conversions this is called a b testing and it helps save money and get better results a good agency will use this data to improve future campaigns and show clients what is working


how ga4 helps with retargeting

ga4 also helps with retargeting you can create audiences inside ga4 like people who added to cart but didnt buy or people who watched a video but didn’t sign up then you can send these audiences to google ads and show them special messages or offers this is super helpful for ecommerce or service businesses where people need more time before buying a marketing agency in egypt can plan this and run smart retargeting campaigns that bring people back to the site


how ga4 helps digital marketing agencies

social media marketing agencies need ga4 to see what happens after the click likes and views are not enough anymore people want real results like leads and sales so ga4 helps track every step after the ad and shows the full picture from where the user came what they did how long they stayed if they clicked what they bought and if they came back later all this info helps the agency improve content choose better platforms and explain the value to clients


ga4 and reporting to clients

  • with ga4 they can show charts and tables that explain what is going on in a simple way

custom reports and ga4 explorations

  • or how people in cairo vs alexandria behave differently on the site
