Why GA4 is important for your website
Google Analytics 4 (GA4) is Google's free analytics platform. It shows who visits your website, where they come from and what they do, including which visits turn into leads and sales. Universal Analytics, the previous version, stopped processing data on 1 July 2023, so GA4 is now the standard.
When GA4 is set up properly you can answer the questions that drive growth:
- Which marketing channel brings the most revenue, not just clicks?
- Which pages and products convert, and which lose visitors?
- Where do people drop off in the checkout or contact process?
- Are your Facebook and Google ads actually profitable?
- Which blog posts bring customers from Google?
Why most GA4 setups are wrong
Installing the GA4 code takes minutes, but the default setup measures very little that matters to a business. Common problems:
| Problem | Effect |
|---|---|
| No conversions (key events) marked | You can't see leads or sales in reports |
| Purchase event missing value or currency | Revenue reports show zero or wrong numbers |
| Installed twice (plugin + theme + GTM) | Double-counted visits and inflated numbers |
| Data retention left at 2 months | Older detailed data disappears from explorations |
| Your own team's visits counted | Misleading traffic and conversion rates |
| Search Console and Ads not linked | Missing search and ad performance in one place |
GA4 for Bangladeshi businesses
Many local businesses sell through a mix of website, Facebook, WhatsApp and phone calls. A good setup tracks WhatsApp and call button clicks, form submissions and cash-on-delivery orders, with revenue in BDT, so you see the full picture, not just online card payments.
GA4, Pixel and server-side tracking
GA4 shows your whole marketing picture; the Meta Pixel feeds Facebook's ad algorithm. They work best together, and both become more accurate with server-side tracking. If your Facebook numbers look wrong, see the Pixel fix service.
