Sales Chrome extension: from 2 minutes to 5 seconds per prospect, 10K+ profiles processed
Sales reps kept copying details from LinkedIn profiles and Salesforce leads into campaigns, contact lists, and the CRM. I built a Chrome extension in three weeks that does it for them: it recognises the page, pulls out the person and company details, and opens a side panel where the rep adds them to a campaign, list, or CRM workflow without leaving the page. Each prospect now takes about 5 seconds instead of 2 minutes. It has 1,000+ installs, 200+ active users, and has processed 10K+ profiles.
Reps found prospects on LinkedIn and in Salesforce, then copied every detail by hand into other tools, checking for duplicates as they went.
What I built
A Manifest V3 Chrome extension that detects LinkedIn profiles and Salesforce leads, extracts and scores them, and runs campaign, contact-list, and CRM actions from a side panel.
The result
About 5 seconds per prospect instead of 2 minutes. 1,000+ installs, 200+ active users, and 10K+ profiles processed. Published on the Chrome Web Store.

The problem: sales reps copying data between too many tabs
A rep finds someone on LinkedIn, copies their details into the CRM, finds the right campaign, checks the person isn't already in it, and adds them. Then does it again for the next prospect. It's slow, it's boring, and copy-paste errors end up in the CRM.
Done by hand, that took about 2 minutes per prospect. The company wanted those actions to live on the page the rep is already looking at.
How the sales Chrome extension works
The extension recognises supported LinkedIn profiles and Salesforce lead pages on its own. It reads the person and company details, turns them into a clean contact record, scores the lead, and opens a side panel with the actions that make sense for that person.
01
Open a profile
A LinkedIn profile or Salesforce lead, as part of normal work.
02
The extension recognises it
It only activates on supported pages.
03
Details are pulled out
Name, title, company, location, experience, and more.
04
Pick an action
Add to a campaign, a contact list, or a CRM workflow.
05
See the result
Done, already added, or a clear error.
Extracting data from LinkedIn and Salesforce pages reliably
LinkedIn and Salesforce load content gradually and change their page structure often, so a simple scraper breaks. The extension waits for the right content to appear, reads only supported page types, and handles missing fields instead of failing.
Each platform has its own adapter that converts its data into one shared contact format. The side panel and the business actions work on that format, so adding a new platform later means writing one adapter, not rebuilding the extension.
Duplicates, errors, and the messy real world
Before any action runs, the extension checks whether the person already exists in that campaign or list and says so. Expired logins, unsupported pages, missing data, API failures, and network drops each get a clear message, so reps never wonder whether something worked.
It also stays out of the way: detection and extraction only run on supported pages, so the extension adds no overhead anywhere else.

Key decisions
01
One adapter per platform, one shared workflow
LinkedIn and Salesforce look completely different, but the actions are the same. Separating them keeps the core reusable.
Trade-off: An extra layer to design up front.
02
One contact format for every source
Different platforms name the same fields differently. Converting everything to one format means the actions work the same everywhere.
03
Manifest V3
Chrome's current extension standard, required for publishing on the Chrome Web Store.
Trade-off: Different background-script rules to work around.
What the client said
“Our reps used to copy every prospect by hand. Now it's a couple of clicks on the LinkedIn page, and duplicates get caught before they hit the CRM.”
Can you build a custom Chrome extension for my sales team?
Yes. A custom extension can read the pages your team already uses, like LinkedIn or Salesforce, and push that data into your own tools with one click. It's worth it when reps repeat the same copy-and-paste work many times a day.
How do sales extensions get data from LinkedIn profiles?
They read the information shown on the page the user is viewing, then convert it into a structured contact record. They should only work on pages the user opens themselves, and stay within the platform's terms of use.
How long does it take to publish an extension on the Chrome Web Store?
Review is often a few days, but it can take longer for extensions that request broad permissions. Asking only for the permissions you need, and explaining why in the listing, usually makes review smoother.
