    Attribute organic traffic and conversions to specific keywords and content by connecting GA4.

    What GA4 adds on top of GSC

    Connecting Google Analytics 4 (GA4) to LemRank provides additional data beyond what Google Search Console (GSC) offers. GSC primarily focuses on search engine performance, such as impressions, clicks, click-through rate (CTR), and average position for keywords.

    GA4, however, provides deeper insights into user behavior on your website after they arrive from search. This includes metrics like engaged sessions, average engagement time, and conversions. By integrating GA4, you can:

    • Attribute conversions: Understand which keywords and landing pages are driving specific user actions, such as form submissions, purchases, or newsletter sign-ups.
    • Analyze user engagement: See how users interact with your content after clicking through from search results.
    • Identify high-value organic traffic: Pinpoint the segments of your organic audience that are most engaged and valuable.

    This combined data allows for a more comprehensive understanding of your organic search performance, from initial search visibility to on-site user actions and business outcomes.

    The OAuth connect flow

    Connecting your GA4 property to LemRank is performed through an OAuth 2.0 flow. This is a standard and secure authorization process that allows you to grant LemRank access to specific data without sharing your Google login credentials directly.

    The process involves the following steps:

    1. Navigate to the "Integrations" section within your LemRank project settings.
    2. Select the option to connect Google Analytics 4.
    3. You will be redirected to a Google authentication page.
    4. Sign in with the Google account that has access to your GA4 property.
    5. You will be prompted to grant LemRank specific permissions to view your Google Analytics data. These permissions are limited to reading aggregated data required for reporting.
    6. After granting permissions, you will be redirected back to LemRank to complete the setup.

    LemRank's AI prompts, which may interact with your connected data, run securely in Supabase Edge Functions. These functions execute in a server-side environment, meaning your data access is managed through secure server-to-server communication using a LOVABLE_API_KEY. No AI prompts or data access attempts occur directly in your browser.

    Selecting your GA4 property and view

    After successfully completing the OAuth flow, LemRank will present you with a list of GA4 properties and their associated data streams that your connected Google account has access to.

    1. From the dropdown menus, select the specific GA4 property you wish to connect to your LemRank project.
    2. Next, choose the relevant data stream. Most users will have a "Web" data stream for their website.
    3. Confirm your selection. This choice determines which GA4 data LemRank will pull for analysis.

    It is crucial to select the correct property and data stream to ensure that the reported metrics accurately reflect your website's performance.

    Mapping GA4 events to conversions

    Once your GA4 property is connected, you can map specific GA4 events to "conversions" within LemRank. This feature allows you to define what constitutes a successful action on your website and track its performance in relation to your organic search efforts.

    In GA4, all user interactions are considered events. Some events are automatically collected (e.g., page_view, scroll), while others are recommended or custom events you configure (e.g., form_submit, purchase). You can also mark any event as a "conversion" directly within the GA4 interface.

    To map GA4 events to conversions in LemRank:

    1. Go to the "SEO Goals" or "Conversions" section within your LemRank project settings.
    2. You will see an option to "Map GA4 Events".
    3. LemRank will display a list of events from your connected GA4 property that are marked as conversions in GA4.
    4. Select the GA4 events you want to track as conversions within LemRank. For example, if you track a generate_lead event in GA4 as a conversion, you can select that event in LemRank.
    5. Save your changes.

    LemRank will now pull data for these specified conversion events, allowing you to see which keywords and pages contribute to these valuable user actions. LemRank only stores aggregated GA4 metrics related to your selected conversions and other relevant performance indicators. It does not store any personally identifiable information (PII) or session-level data.

    Data lag and refresh cadence

    When you connect your GA4 property, LemRank initiates the data retrieval process.

    • Initial data pull: The first data pull may take some time to complete, depending on the volume of historical data available and the number of events configured.
    • Daily refresh: After the initial sync, your GA4 data in LemRank will refresh daily. This ensures that the insights you see are up-to-date.
    • Conversion data lag: It is important to note that GA4 conversion data has a processing lag of 24 to 48 hours. This means that conversions that occurred today might not appear in LemRank until tomorrow or the day after. This delay is inherent to how GA4 processes and makes data available via its API.

    Plan your analysis accordingly, understanding that the most recent conversion figures will always reflect this processing window.

    Troubleshooting missing data

    If you encounter issues with missing or incomplete GA4 data in LemRank, consider the following troubleshooting steps:

    1. Check connection status: Verify that your GA4 connection status in LemRank's "Integrations" section shows as active and healthy. If the connection is broken, re-authenticate using the OAuth flow.
    2. Verify GA4 permissions: Ensure that the Google account used for the OAuth connection has the necessary permissions to access the selected GA4 property and its data. A "Viewer" role or higher for the GA4 property is typically sufficient.
    3. Confirm property and data stream selection: Double-check that you selected the correct GA4 property and data stream within LemRank settings. An incorrect selection will result in no relevant data appearing.
    4. GA4 event configuration: If you are missing conversion data, confirm that the events you mapped in LemRank are indeed configured as "conversions" within your GA4 property. Also, ensure these events are actively collecting data in GA4.
    5. Consider data lag: Remember the 24-48 hour processing lag for GA4 conversion data. Data from the previous day may not be fully visible until the next day.
    6. Data filtering in GA4: Ensure that no unintended data filters are applied within your GA4 property that might exclude the data you expect to see.
    7. Contact support: If the issue persists after reviewing these points, contact LemRank support for further assistance. Provide details about the GA4 property, the specific data you expect to see, and the steps you have already taken to troubleshoot.

    Frequently asked questions

    Do I need both GSC and GA4?

    GSC covers ranking, impressions, and clicks. GA4 covers what happens after the click (sessions, conversions, revenue). Together they close the loop.

    Which GA4 permission level do I need?

    Viewer is sufficient. LemRank never writes to GA4.

    Can I use Universal Analytics instead?

    No — Google sunset UA in July 2023. All new integrations use GA4.
