Beginner’s Guide: M&A Digital Checklist of What to Merge, Update, and Watch Out For

With mergers and acquisitions, there are a million moving parts. But one area that often gets overlooked until it’s too late is digital. By digital, I mean all the online assets that represent your firms: websites, social media accounts, Google Business profiles, email platforms, CRMs, analytics and even paid ads. If you don’t handle these properly, you can confuse clients, lose SEO juice or accidentally post something from the wrong account (yikes). Here’s a practical checklist to guide you through the post-M&A digital cleanup and merging process.

1. Website

• Audit content: Map both sites. Decide which one becomes the primary home, then outline what content to keep, merge or retire.
• Domain considerations: If the acquired firm has its own domain, decide whether to redirect it to the primary firm’s site. 301 redirects are your friend. They can help preserve SEO.
• Quirks to watch: Internal links can break if URLs change. Double-check navigation menus and forms after any merge.
• Next steps: Update branding (logos, colors, messaging), and ensure all legal disclaimers are consistent.

2. Google Business / Google Maps

• Audit listings: Check if the acquired firm has its own profile. Make sure name, address and phone info (NAP) are correct.
• Merge vs. retire: If there are duplicate listings, request a merge via Google My Business. Keep the profile with the most reviews and history.
• Quirks: Google can be finicky. Sometimes a merge request gets denied. You may need to claim both listings first, or contact Google support.

While you’re working on the logistics, consider other optimizations to your Google Business profile. Add pictures, update services and encourage clients to leave reviews

3. Social Media Accounts

• Audit platforms: Facebook, LinkedIn, Instagram, Twitter/X, YouTube, TikTok—whatever is live. Check followers, engagement, and admin access.
• Decide on consolidation: Can you merge pages or accounts, or do you need to sunset one account and redirect followers to the main account?
• Quirks: Some platforms don’t allow merges, and follower counts may not transfer. Screenshots of analytics before changes can be a lifesaver.
• Next steps: Update bios, profile photos, cover images and company info. Schedule a “rebrand announcement” post if needed.

Don’t forget your people! Staff profiles often reflect company changes. Encourage them to update their job titles, header images and company names.

4. Email & Marketing Platforms

• Audit lists: Export and clean email lists from both firms. Remove duplicates and opt-outs before merging.
• Consolidate accounts: Determine which platform will be primary (Mailchimp, HubSpot, Constant Contact, etc.). Migrate templates, workflows and automations carefully.
• Quirks: Some platforms throttle or limit imports. Test with a small batch first to avoid chaos.

If switching platforms, consider a pre-merge client notification. A quick note letting clients know emails will come from a new address can prevent messages from landing in spam and keep communications seamless.

5. CRM Systems

• Audit records: Client and prospect data may exist in different CRMs. Identify duplicates and conflicting entries.
• Merge thoughtfully: Prioritize the system with better automation and reporting. Tag imported records so you know their origin.
• Quirks: Integration with other platforms (email, analytics, accounting software) can break after a merge. Plan for testing and cleanup.

6. Analytics & Paid Ads

• Audit accounts: Google Analytics, Google Tag Manager, Facebook Ads, LinkedIn Ads, etc. Make sure you have admin access.
• Merge or transfer: Link the acquired firm’s tracking codes to your primary accounts. Update conversion goals, audiences and remarketing lists.
• Quirks: Don’t delete old accounts before confirming data has been properly transferred—historical reporting is important.

Before making any changes, document your current campaigns, audiences and conversion goals. That way, you have a clear record to reference.

7. SEO & Online Directories

• Audit backlinks: Ensure important external links point to the new, consolidated site.
• Update citations: Directories, industry listings, review sites—make sure NAP info is consistent.
• Quirks: Some directories are slow to update. Keep a spreadsheet and check back periodically.

Consider setting a reminder to audit directories three to six months after the merge. SEO effects can take time to show, and this ensures nothing slips through the cracks.

8. Passwords & Admin Access

• Audit all logins: Social media, Google Business, hosting, email platforms, CRMs, ad accounts, analytics.
• Centralize management: Consider a password manager (LastPass, 1Password) for secure storage.
• Quirks: Don’t assume access transfers automatically—ownership may need to be requested from previous admins.

Double-check access for every platform, even the small ones that seem inconsequential—they can cause big headaches if someone suddenly loses access.

Final Thoughts

M&A can be messy, stressful and full of surprises, but handling your digital assets early makes life a lot easier. Think of this checklist as your safety net: it won’t solve culture clashes or integration headaches, but it will prevent clients from seeing outdated information, broken links or posts from “the wrong firm.”

Take it step by step, document as you go and don’t be afraid to ask for help if platforms get tricky. Remember, you’re not just merging firms, you’re merging how the world sees your firm online. And that’s worth doing right.
