How to manage duplicate leads from a lead provider

Receiving duplicate leads from a provider can waste time and resources, but it's a common issue that you can manage with proper systems. The key is to have a clear process for identifying, categorizing, and addressing duplicates to maintain efficiency.

Understanding why duplicates occur

Duplicates can happen for several reasons. Sometimes, a seller texts multiple times from different numbers or with slightly varied wording. Your provider might also source from different channels, leading to the same property showing up more than once. It's not always malicious; sometimes it's just data overlap.

The crucial part is not to blame, but to understand and implement a system to handle it. Your time is valuable, and chasing the same seller twice is inefficient.

Setting up your CRM for duplicate detection

Your CRM should be your first line of defense. Configure it to detect duplicates based on key identifiers: property address, owner name, and phone number. Most CRMs have built-in features for this; ensure yours is optimized.

When a new lead comes in, it should automatically flag potential matches. This saves your team from manually sifting through records and prevents redundant outreach.

Manual vs. automated duplicate identification

Automated systems are great for exact matches. However, some duplicates might be 'fuzzy,' meaning slight variations in address (e.g., 'Main St' vs 'Main Street') or owner name (e.g., 'John Smith' vs 'J. Smith'). You'll need a manual review process for these.

Dedicate a specific time each day or week to review flagged potential duplicates. This is a quick task if done regularly, preventing a backlog of unaddressed leads.

Establishing a communication protocol with your provider

Before you start, understand your lead provider's policy on duplicates. Speed to Seller filters for duplicates before listing, but if one slips through, we need to know. Have a clear, documented process for reporting duplicates and requesting credits or replacements.

Keep records of when you reported a duplicate and the outcome. This ensures accountability and helps you track the provider's responsiveness and overall data quality.

Categorizing and prioritizing duplicate leads

When a duplicate is identified, categorize it in your CRM. Is it an exact match? A close match? Which one came in first? Which one has more complete data? Prioritize the original or most comprehensive lead.

The duplicate can then be marked as 'duplicate - do not contact' or archived, ensuring your team focuses on the primary record and avoids confusing the seller with multiple contacts for the same property.

Impact on follow-up sequences

Duplicates can derail your carefully planned follow-up sequences. If an automated system tries to send texts or emails to two records for the same seller, it looks unprofessional and can annoy the seller.

Ensure your CRM's automation rules are tied into your duplicate management. If a lead is marked as a duplicate, it should be automatically removed from any active outreach campaigns to prevent double messaging.

Reviewing provider accountability

Regularly review your duplicate rate from each lead provider. If you're consistently seeing a high number of duplicates from one source, it's a red flag. Discuss this data with your provider.

A reputable provider should be willing to work with you to reduce duplicates and maintain data hygiene. If issues persist, it might be time to reconsider that source's effectiveness for your business.

Questions people ask

Are duplicates always the lead provider's fault?

Not always. Sellers can text multiple times or use different numbers. Your own internal systems might also create duplicates if not properly configured. It's often a shared responsibility to manage.

Should I reach out to a duplicate lead again?

Generally, no. Once you identify a duplicate, consolidate the information into one primary lead record and discontinue outreach to the duplicate. Contacting the same seller multiple times can appear disorganized or spammy.

How can I avoid getting duplicates in the first place?

You can't entirely avoid them, as they're inherent in data processing. However, a good lead provider like Speed to Seller actively filters for duplicates before listing leads. Your CRM's detection rules are also key.
