# Analytics you can make decisions on — implemented by engineers, not tag-manager tourists.

If GA4 revenue doesn't match your orders, half your traffic is "unassigned," or your site is slow from twenty marketing tags, the implementation is broken. Reed Dynamic rebuilds it: server-side tagging, consent mode, correct eCommerce events, and reporting your team trusts.

## Analytics FAQs

**

### Why does our GA4 data look wrong?

**

The usual culprits: duplicate or missing tags after a redesign, no consent mode so EU/CA traffic is dropped, ad blockers and Safari ITP killing client-side tags, mis-configured eCommerce events, and GA4 data thresholding hiding rows. We audit all of it and fix the implementation — see our guide to [removing GA4 thresholding](https://reeddynamic.com/blog/removing-thresholding-applied-in-google-analytics-4-ga4-reporting-a-step-by-step-guide/).

**

### What is server-side tagging and do we need it?

**

Instead of every marketing tag firing in the visitor's browser, a server you control (Google Tag Manager server container or Cloudflare Zaraz) receives one event and forwards it to GA4, Ads, Meta, etc. Result: faster pages, far less data loss to ad blockers and ITP, and control over what PII leaves your site. If you spend meaningfully on ads or your Core Web Vitals suffer from tag bloat, yes.

**

### How much does GA4 / analytics work cost?

**

A GA4 audit with fixes runs $2,500–$6,000. Full implementation with server-side tagging, consent mode, and eCommerce tracking runs $8,000–$25,000. BigQuery + Looker Studio reporting is scoped separately. See [pricing](https://reeddynamic.com/pricing/).

**

### Do you handle consent / GDPR / CCPA requirements?

**

Yes — Consent Mode v2, CMP integration (Cookiebot, OneTrust, Osano, or a lightweight custom banner), regional rules, and privacy-first analytics alternatives where appropriate. Read our [privacy-first web development guide](https://reeddynamic.com/blog/privacy-first-web-development-2026/).

**

### Can you track eCommerce revenue correctly on Magento, Shopify, or WooCommerce?

**

Yes — full purchase funnel events (view_item → add_to_cart → begin_checkout → purchase) with item data, refunds, and server-side purchase confirmation so revenue matches your order system.

**

### Is this SEO?

**

It's the measurement side of it. Pairs with our [technical SEO](https://reeddynamic.com/services/technical-seo/) work: Search Console + GA4 + BigQuery in one reporting layer.
