Analytics buyer's guide
Written by the Happy Valley editors, reviewed by Mustafa Gezer. Updated October 20, 2026.
What is Analytics software?
Analytics software collects and reports how people find, use and convert on your website or app, turning raw visits and events into answers about traffic, behaviour and revenue. Web analytics tools such as Google Analytics, Plausible and Matomo focus on pageviews, sources and campaigns, while product analytics tools such as Mixpanel, Amplitude and PostHog track user-level events, funnels, retention and cohorts inside a product.
Teams use analytics to see which channels bring customers, where users drop off, which features drive retention and whether a change actually improved anything. Marketers, founders, product managers, growth teams and data analysts are the main users.
The category overlaps with its neighbours but is not the same: mobile measurement partners such as AppsFlyer and Adjust attribute app installs to ad spend, behaviour tools such as Hotjar and Clarity show heatmaps and recordings, and dashboard tools such as Databox combine metrics from many systems rather than collecting them.
Key features to look for
- Event and funnel tracking
- Custom events, funnels and conversion goals turn traffic into business answers. Check whether events are captured automatically or defined by hand, and whether you can edit definitions retroactively.
- Privacy and consent handling
- Cookieless tools such as Plausible, Fathom and Simple Analytics can avoid consent banners in many setups, while cookie-based tools need a proper consent flow. Check where data is stored and whether IP addresses are anonymised.
- Retention and cohorts
- Retention curves show whether users come back, which matters more than signups for SaaS and apps. Check that cohorts can be split by plan, acquisition source or behaviour.
- Session replay and heatmaps
- Recordings explain why a funnel step fails. PostHog, Hotjar and Microsoft Clarity include them; check masking of personal data and any sampling limits.
- Data ownership and export
- You should be able to export raw events or sync them to a warehouse. Check API limits, data retention per plan and self-hosting options such as Matomo, Umami or Countly.
- Attribution and campaign tracking
- UTM handling, referrer data and ad cost imports decide how you judge marketing spend. For apps, a mobile measurement partner such as AppsFlyer, Adjust or Singular handles install attribution and SKAdNetwork.
- Experiments and feature flags
- Built-in A/B tests and flags let you measure impact without another tool. PostHog, Amplitude and Mixpanel offer them; check the statistics method and whether flags are billed separately.
How to choose Analytics software
- 1
Write down your questions
List the 5 to 10 questions you need answered every week, such as which channel brings paying users. Traffic questions point to web analytics; behaviour inside the product points to product analytics.
- 2
Decide your privacy posture
Choose between cookie-based tools with a consent banner and cookieless tools. Your legal basis under GDPR or KVKK and your audience decide how much data you can collect.
- 3
Estimate your volume
Count monthly pageviews or events and project 12 months ahead, because most pricing scales with volume. Autocapture can multiply event counts quickly.
- 4
Check the tracking setup
Review SDK coverage for your stack (web, iOS, Android, server) and whether you need a tag manager or a CDP such as RudderStack. Clear documentation saves weeks.
- 5
Test with real traffic
Run the trial on production traffic next to your current tool for two weeks. Differences of a few percent are normal; large gaps reveal setup problems.
- 6
Plan for the warehouse
If you have a data team, check native exports to BigQuery, Snowflake or similar. Owning raw data keeps you from being locked into one vendor's reports.
Analytics pricing

Analytics pricing is usually tied to volume. Web analytics tools such as Plausible, Fathom and Pirsch charge by monthly pageviews in tiers, while product analytics tools such as Mixpanel, Amplitude and PostHog charge by tracked events or monthly tracked users, usually with a generous free tier. Google Analytics and Microsoft Clarity are free, and self-hosted Matomo or Umami have no licence fee but cost server time and maintenance.
Watch for hidden costs: session replay, experiments, data retention beyond a year, warehouse export and extra seats are often add-ons. Autocapture can inflate event counts, and mobile attribution platforms usually quote custom prices based on attributed installs or conversions. Annual plans typically come with a discount.

Analytics trends in 2026
AI assistants are now standard: Mixpanel, Amplitude and Microsoft Clarity let you ask questions in plain language and get charts or session summaries, and several vendors expose data to AI agents through MCP servers. Product analytics, session replay, surveys and experiments are merging into single platforms, with PostHog and Amplitude bundling all of them.
Privacy pressure keeps growing. Google Consent Mode v2 became mandatory for advertisers using EEA data in 2024, which pushed many sites toward cookieless tools or server-side tracking. On mobile, attribution continues to shift to aggregated, privacy-preserving methods such as Apple's SKAdNetwork and AdAttributionKit.
Common mistakes to avoid
- Installing a tool without defining events and naming conventions, which leaves months of unusable data.
- Tracking every click with autocapture and then paying for millions of events nobody looks at.
- Collecting cookie data from EU or Turkish visitors without a valid consent flow or legal basis.
- Comparing numbers between two tools and assuming one is broken, when ad blockers, bots and session definitions explain most gaps.
- Keeping raw data only inside the vendor, so switching tools later means losing your history.
Analytics in Turkey
Under KVKK, analytics cookies that are not strictly necessary generally need explicit consent, and since June 2024 transfers abroad, which include US-hosted analytics, usually rely on standard contracts that must be notified to the Authority. Self-hosting Matomo, Umami or Countly on a Turkish server keeps data under your control. Countly has Turkish founders, Prisync and Related Digital are Turkish companies, and BoomSonar adds Turkish-language social listening. Most tools bill in USD by card, so budget for exchange rate swings.
Analytics FAQ

- Is Google Analytics GDPR and KVKK compliant?
- It can be used lawfully, but it needs a consent banner, correct data settings and, for Turkish sites, attention to KVKK rules on transfers abroad. If you want simpler compliance, cookieless tools such as Plausible, Fathom, Simple Analytics or a self-hosted Matomo reduce the personal data you collect.
- What is the difference between web analytics and product analytics?
- Web analytics measures traffic: visitors, sources, pages and campaign conversions. Product analytics measures what identified users do inside an app over time, with funnels, retention and cohorts. Google Analytics and Plausible are web analytics; Mixpanel, Amplitude and PostHog are product analytics.
- Mixpanel vs Amplitude: which should I choose?
- Both are mature event-based product analytics tools with free plans, session replay and experiments. Mixpanel is often seen as quicker to learn for smaller teams, while Amplitude goes deeper on governance, behavioural cohorts and enterprise features. Trial both with the same events before deciding.
- Do I need a cookie banner for privacy-friendly analytics?
- Cookieless tools such as Plausible, Fathom, Pirsch and Simple Analytics do not set cookies or store personal data, so in many setups they do not need a consent banner. Your site still needs a privacy notice, and the final call depends on your legal advice and the other scripts you load.
- How much does analytics software cost?
- Costs range from free (Google Analytics, Microsoft Clarity, self-hosted Matomo or Umami) to enterprise contracts for Amplitude or Pendo. Most paid tools price on pageviews or events, so traffic volume is the main driver; the plan table on this page shows current starting prices.
