Morning Marina. Purchases fell at the end of August. Did something change on our side?
Marina, purchases dropped at the end of August. What changed? I need it for Monday’s review.
Found it. On 27 Aug prospecting moved to /payments, and the form was hidden on phones there. Fixing it today.
Changeline · 27 Aug · Destination changedEach platform logs its own changes, in its own format, for whoever has access. Answering the question means opening all five and asking around.
Conversions usually drop after a change: a budget cut, a new landing page, a broken or duplicated tag, a consent update or a CRM form edit. Find the date the metric moved, then check every change logged in the days before it, across all channels. A marketing change log makes that a two-minute check.
A client asks why conversions dropped on Tuesday. Changeline shows one timeline with every change to Google Ads, Meta Ads, the website and tracking. Google Ads changes are imported automatically, read-only. Zooming from six weeks to the right week shows that a Target CPA change in Google Ads explains the drop, and the change report lists everything that changed in the period.
Changeline is a marketing change log: a shared, to-scale timeline where agencies and in-house growth teams record every change to ads, website, tracking, CRM and product, with who made it and why, so they can explain what moved a metric.
On the 3rd, the client asks why purchases fell in late August.
Open their project, filter to August, and point at the destination change on the 27th. The client already has viewer access to the same timeline. Example scenario.
Monday review: cost per acquisition is up this week.
Filter to last week. A Performance Max budget increase and a new landing page went live the same day, each with the reason. Example scenario.
Pick the last 7, 14 or 30 days, or any two dates. Changeline turns every change in the period into a two-page PDF, ready for the client call.
Every role can generate it, viewers included.
Connect Google Ads read-only. Every 6 hours, budget, bidding, status, campaign and ad changes come in, with who made each one.
Meta Ads import is coming soon.
Changeline started inside a marketing agency. Every month a client asked why a number moved, and we rebuilt the answer from chat threads and memory. Now we log changes as we make them, and use Changeline every day.The Changeline team
About marketing change logs and Changeline.
A marketing change log is a dated record of every change a team makes to campaigns, websites, tracking and CRM: budgets, audiences, creatives, landing pages, tags and automations, with who made each change and why. When a metric moves, the team checks the log for the days before it instead of guessing.
Marketing change tracking means recording every change that can move a metric, such as budgets, audiences, landing pages, tags and automations, with its date, owner and reason. In Changeline you log a change in seconds or import it from Google Ads, then read everything on one to-scale timeline. When a number moves, you check the days before it.
Log anything that can move a number: budget and bid strategy changes, new campaigns and audiences, creatives and ad destinations, site releases and new landing pages, GTM, GA4 and consent changes, CRM automations and form fields, and product launches. Skip single bid tweaks and typo fixes, so the timeline stays easy to read.
Yes. The Free plan has no time limit and asks for no card: 1 project, 2 editors and the last 15 days of change history, with no cap on changes. Upgrade to Pro or Team when you need the full history, more projects, editors or the PDF report, and cancel anytime.
A change takes a few seconds to log: date, title and tag. One unexplained drop in conversions can cost a team hours of digging and a hard client call. You only log changes that can move a number, and Google Ads changes can be imported automatically (Meta Ads is coming soon). Everything you log now stays on the same timeline.
GA4 annotations live inside one analytics property and only people with access to it can see them. Changeline keeps changes from every channel on one to-scale timeline per client, with tags, notes, links, roles and a full edit history, so a whole team and its clients read the same record.
Yes, and Meta Ads keeps an activity history. Each shows only its own changes, as a list, to people with access to that account. Changeline puts them next to website, tracking, CRM and product changes on one axis, so you can see that a budget increase and a landing page change happened in the same week.
On the first connection, the Google Ads API only hands over the last 30 days of changes. From then on, Changeline imports every 6 hours and keeps each change for good, past the 2 years of Google Ads’ own change history. Next year you can compare a period with the same period a year earlier and see what was done then.
Looker Studio has no built-in annotation feature, so teams add text boxes or blend a sheet of dates into their charts. Changeline keeps those changes in a dated, shared timeline that you open next to the report, with the reason for each change.
Yes. Each client gets its own project with its own tags and people. You choose who sees which client, give editors permission to log changes and invite clients as read-only viewers, so the timeline doubles as a record of the work you did.
Changeline runs on Supabase in the European Union (Ireland region), with row-level security so people only see projects they were added to. Every edit is recorded with who made it and when. Changeline only reads your ad accounts if you connect Google Ads, and its server blocks any change to them.
The site and the app work in English, Portuguese (Brazil and Portugal), Spanish, French, Italian, Persian, German, Japanese and Hindi. Changeline picks your browser's language, and you can switch at any time from the language menu.
Yes. Open the project, click Report and pick the period: the last 7, 14 or 30 days or any two dates. You get a two-page report with the number of changes, the split by group and platform, the highlights and every change with its date and value. Save it as a PDF from the browser's print dialog. Viewers can generate it too.
Log the last five changes you remember. It takes a minute, and next time a metric moves you'll know where to look.
