Enhanced Conversions for Financial Advisers: Setup That Improves Google Ads Optimisation

Enhanced Conversions improve the accuracy of your existing conversion tracking by sending hashed first-party customer data (email address, phone number, name, or address) alongside the conversion tag.

When someone clicks your ad and submits a form, Google records the click and the conversion. But if the user cleared cookies between clicking and converting, or converted on a different device, or if consent settings limited tracking, the conversion may not be attributed back to the click that caused it.

Enhanced Conversions solve this by sending a hashed (one-way encrypted) version of the data the user provided in the form -- typically their email address -- to Google. Google matches this hashed data against signed-in Google user data to attribute the conversion back to the correct click, even when cookies are missing.

The result: more conversions are attributed to the campaigns, ad groups, and keywords that produced them. This gives Smart Bidding a more complete picture of what is working, which improves its bid predictions.

For financial services, where conversion volumes are already low, recovering even 10-15% of "lost" conversions through Enhanced Conversions can meaningfully improve Smart Bidding performance.

There are two implementation methods:

Google Tag (gtag.js) method: If your conversion tracking uses the Google tag, you add Enhanced Conversion fields to your existing conversion tag. When the user submits a form, the tag captures the email and/or phone number, hashes it client-side using SHA-256, and sends the hashed value to Google.

In practice, this means modifying your form submission handler to pass the user's data to the Google tag before or alongside the conversion event. For a typical enquiry form:

1. In Google Ads, go to Goals > Conversions > Settings and enable Enhanced Conversions
2. Select "Google tag" as your data source
3. Configure the tag to capture email from your form field
4. Test using the Google Tag Assistant to verify hashed data is being sent

Google Tag Manager method: If you use GTM, create user-provided data variables that read the form field values (email, phone), and attach them to your conversion event tag. GTM handles the hashing automatically.

1. In your Google Ads conversion tag in GTM, enable "Include user-provided data from your website"
2. Create a data layer variable or DOM element variable that reads the email input field
3. Map it to the "Email" field in the user-provided data settings
4. Publish and test

Both methods produce the same result. Use whichever matches your existing tag setup.

Important for financial services: the data is hashed before it leaves the user's browser. Google receives a SHA-256 hash, not the raw email address. This is a one-way hash -- it cannot be reversed. You are not sending personal data to Google in a way that conflicts with privacy obligations, though you should still update your privacy policy to disclose the use of Enhanced Conversions.

Enhanced Conversions for web improve attribution of existing online conversions. Offline conversion imports go further: they tell Google what happened after the form submission.

The concept: when a lead from Google Ads progresses through your sales pipeline -- from enquiry to qualified lead to appointment to paying client -- you import those downstream events back into Google Ads with their associated value. Google then knows not just which clicks produced leads, but which clicks produced clients.

This is transformative for Smart Bidding. Instead of optimising for "more form fills," the algorithm optimises for "more clicks that eventually become clients." The difference in targeting precision is substantial.

How it works:

1. When a user clicks your ad and submits a form, capture the Google Click ID (GCLID) alongside their contact details. Most CRM systems have fields or integrations for this.

2. As the lead progresses through your pipeline, update their status in your CRM: Enquiry > Qualified > Appointment Booked > Attended > Client.

3. Periodically (daily or weekly), export the leads that reached key milestones and upload them to Google Ads as offline conversions, with the GCLID and the conversion value.

Google then attributes these downstream conversions back to the original click, keyword, and ad that produced them. Over time, Smart Bidding learns that clicks from certain keywords, demographics, times of day, or geographic areas are more likely to produce paying clients -- not just form fills.

The main barrier to offline conversion imports is connecting your CRM to Google Ads. The approach depends on your CRM:

Salesforce, HubSpot, Zoho: These have native or marketplace integrations with Google Ads offline conversion imports. Typically you configure which pipeline stages map to conversion actions and the integration handles the rest.

Intelliflo, Adviser Office, Xplan, other adviser-specific CRMs: These rarely have native Google Ads integrations. Options include:

• Export a CSV of converted leads weekly and upload manually to Google Ads
• Use Zapier or Make to create an automated bridge between your CRM and Google Ads
• Build a simple API integration that posts conversion events when leads change stage

Spreadsheet-based tracking: If you track leads in a spreadsheet (which many smaller firms do), you can still import offline conversions. Add a GCLID column to your lead tracker, populate it from your form submissions, and upload a CSV to Google Ads monthly with the GCLIDs that became clients.

The GCLID is captured by adding ?gclid={gclid} as a hidden field in your lead form. Most form builders (Gravity Forms, Typeform, HubSpot Forms) support hidden fields populated from URL parameters. Your landing page form should always capture this.

Even a manual monthly upload of 5-10 client conversions provides Smart Bidding with dramatically better signal than form fills alone.

Google also offers "Enhanced Conversions for leads" -- a hybrid approach that combines the hashing of Enhanced Conversions with the downstream tracking of offline imports.

Instead of passing GCLIDs through your CRM, you send the hashed email address of the lead when they submit the form. Later, when that lead becomes a client, you upload their hashed email and the conversion event. Google matches the hashed emails to attribute the offline conversion to the original click.

This is useful when:

• Your CRM does not support GCLID capture
• You have multiple touchpoints between ad click and form submission (so the GCLID is lost)
• You want a simpler implementation that does not require URL parameter tracking

The trade-off: matching by hashed email is less precise than matching by GCLID, because the user must have been signed into Google with the same email address. Match rates are typically 60-80%, versus near-100% for GCLID-based imports.

For most adviser firms, the GCLID approach is more reliable if your form can capture it. Use Enhanced Conversions for leads as a fallback or complement.

Once you are importing offline conversions, you can configure Smart Bidding to optimise for downstream events rather than form submissions:

Create separate conversion actions for each pipeline stage: "Qualified Lead," "Appointment Booked," "Client Won." Assign realistic values to each (a qualified pension lead might be worth £200, a won client £3,000).

Set your primary conversion action to the most valuable event that occurs with sufficient volume. If you win 5 clients per month from Google Ads, that is too few for Smart Bidding to optimise against directly. But if you qualify 20 leads per month, "Qualified Lead" as the primary conversion action gives enough signal.

Use Target CPA or Target ROAS based on the downstream metric. A Target CPA of £200 per qualified lead is a different (and more useful) target than a Target CPA of £80 per form fill.

The shift from optimising for form fills to optimising for qualified leads or clients is the single highest-impact change you can make to a financial adviser lead generation Google Ads account. The CPL may appear to increase (because you are now measuring fewer, higher-quality conversions), but cost per client decreases because the algorithm is finding better prospects, not just more form fillers.

This is also where broad match starts to deliver. With accurate downstream conversion data, Smart Bidding can intelligently navigate broad match queries -- bidding aggressively on signals that predict real clients and pulling back on signals that predict tyre-kickers. Without that data, broad match is just expensive exploration.

Enhanced Conversions send hashed personal data to Google. While hashing is a privacy-preserving technique (the data cannot be reversed), you should:

• Update your website privacy policy to disclose the use of Enhanced Conversions
• Ensure your cookie consent mechanism allows Google Ads conversion tracking
• Configure consent mode in GA4 and your Google tags so that Enhanced Conversions only fire when the user has consented to marketing cookies
• For offline imports, ensure your CRM data processing is covered by your existing privacy notice -- you are sharing hashed identifiers with a third-party advertising platform

The existing GA4 and Consent Mode setup guide covers the consent configuration in detail. Enhanced Conversions work within that framework -- they respect the consent signals you have already configured.

For FCA-regulated firms, there is no specific regulatory restriction on using Enhanced Conversions. The data processing falls under standard GDPR provisions for marketing purposes, which your existing privacy framework should already cover. If in doubt, check with your compliance officer or DPO that your privacy notice covers the sharing of hashed contact information with advertising platforms for conversion measurement purposes.
