Best Practices for LENS AI

Get more accurate, actionable insights by following these best practices when asking questions.

Writing Better Questions​

Be Specific About Time​

❌ Vague: "How is traffic?"

✅ Better: "How did traffic change last week compared to the week before?"

✅ Best: "Compare daily traffic for Jan 8-14 vs Jan 1-7, broken down by source"

Include Context​

❌ Missing context: "Why did conversions drop?"

✅ With context: "Why did conversions drop on January 10th? We launched a new landing page that day."

Specify Metrics​

❌ Ambiguous: "How are we performing?"

✅ Clear: "What's our conversion rate, average order value, and total revenue for this month?"

Name Your Segments​

❌ Unclear: "How's mobile doing?"

✅ Precise: "What's the conversion rate for mobile users from paid search in the US?"

Question Templates​

Traffic Analysis​

"Show me [metric] for [time period], broken down by [dimension]"

Examples:
• "Show me sessions for last 30 days, broken down by source"
• "Show me pageviews for this week, broken down by device"
• "Show me unique users for January, broken down by country"

Conversion Analysis​

"What's the [conversion type] rate for [segment] over [time period]?"

Examples:
• "What's the purchase rate for mobile users over the last 7 days?"
• "What's the signup rate for UK visitors over this quarter?"
• "What's the add-to-cart rate for organic traffic over Black Friday week?"

Comparison Questions​

"Compare [metric] for [segment A] vs [segment B] during [time period]"

Examples:
• "Compare conversion rate for new vs returning visitors during January"
• "Compare revenue from Google vs Facebook campaigns last month"
• "Compare mobile vs desktop bounce rate this week"

Trend Analysis​

"How has [metric] trended over [time period]? Highlight any [anomalies/changes]"

Examples:
• "How has conversion rate trended over the last 90 days? Highlight any drops"
• "How has traffic from Google trended this year? Note any significant changes"
• "How has average order value trended since we launched the new pricing?"

Investigation Questions​

"Why did [metric] [increase/decrease] on [date/period]? Check [potential factors]"

Examples:
• "Why did traffic spike on March 15? Check for referral sources"
• "Why did conversion rate drop last Tuesday? Check by device and source"
• "Why did revenue increase 40% yesterday? Break down by product category"

Conversation Techniques​

Build on Previous Answers​

LENS remembers context. Use it:

You: What was our conversion rate last week?
LENS: 2.3%, down from 2.8% the week before...

You: Break that down by traffic source
LENS: [Uses same time period automatically]
      Google Ads: 2.8%
      Organic: 1.9%
      ...

You: Why is organic lower?
LENS: [Investigates organic specifically]
      Organic conversion rate is lower because...

Ask for Recommendations​

You: Which campaigns should I scale based on last month's performance?

LENS: Based on ROAS and volume, I recommend:

1. Scale: "Winter Sale - Retargeting" (ROAS 4.2, €12k spend)
2. Scale: "Brand Search" (ROAS 6.8, €5k spend)
3. Test increase: "Lookalike Audiences" (ROAS 2.8, €3k spend)

Campaigns to reduce:
• "Cold Audiences - Interest" (ROAS 0.8)

Request Specific Formats​

You: Give me a table comparing all traffic sources for last month,
     sorted by conversion rate, including sessions, conversions,
     and revenue columns

LENS:
| Source      | Sessions | Conversions | CR    | Revenue  |
|-------------|----------|-------------|-------|----------|
| Email       | 12,450   | 498         | 4.0%  | €24,900  |
| Google Ads  | 45,230   | 1,130       | 2.5%  | €45,200  |
| Organic     | 34,120   | 682         | 2.0%  | €27,280  |
...

Common Mistakes to Avoid​

Don't Ask Multiple Unrelated Questions​

❌ "What's our traffic? Also, what's the best performing campaign? And can you show me revenue by country?"

✅ Ask one topic at a time, then follow up.

Don't Assume LENS Knows Your Goals​

❌ "Is this good?"

✅ "Is a 2.3% conversion rate good compared to our historical average?"

✅ "How does our 2.3% conversion rate compare to last year?"

Don't Forget Time Zones​

If your data spans multiple time zones:

✅ "What was traffic on January 10th PST?"

✅ "Show me hourly traffic in UTC"

Don't Overlook Segments​

Generic questions get generic answers:

❌ "Why is bounce rate high?"

✅ "Why is bounce rate high for mobile users from Facebook ads landing on the homepage?"

Getting Help with LENS​

When LENS Isn't Sure​

LENS will tell you when confidence is low:

LENS: I found a correlation between the traffic drop and your
      Google Ads pause, but I'm only 60% confident this is the
      main cause. Other factors might include:
      • Server response time increased 200ms that day
      • It was a holiday in Germany (your second-largest market)

      Want me to investigate any of these further?

When Data Is Insufficient​

LENS: I don't have enough data to answer this reliably.

      You asked about conversion rate by city, but:
      • 73% of sessions have no city data
      • Only 12 cities have >100 sessions

      Would you like me to analyze by country instead?

Set the Response Language​

LENS replies in Spanish (es) or English (en), and keeps the language for the conversation. If you want answers in a specific language, ask your first question in that language or state it explicitly (for example, "Answer in English").

Power User Tips​

Reuse Your Own Question Templates​

LENS does not store saved questions for you, but you can keep your most useful prompts in a personal notes doc and paste them when needed. A practical weekly-review set might be:

1. "Summary of traffic, conversions, revenue for last week vs previous week"
2. "Top 5 performing and bottom 5 performing campaigns by ROAS"
3. "Any anomalies or issues I should know about?"

Ask them one at a time and follow up within the same conversation so LENS keeps the context.

Resume Earlier Conversations​

Conversations are persisted, so you don't have to start over each time:

  • Pick a previous conversation from the sidebar to continue where you left off
  • Each session stays active with a 4-hour sliding window — every message extends it another 4 hours; after 4 hours without activity it goes inactive
  • Start a fresh session with New conversation when you switch topics
  • Delete a conversation when you no longer need it
