Historical Charts Explained

Learn how to read historical ranking charts and interpret movement trends over time.

Updated this week

What it is

Historical Charts allow you to visualize how a keyword’s ranking has changed over time.

With Historical Charts, you can:

  • Track ranking trends across multiple timeframes

  • Compare performance against competitors

  • Review SERP history snapshots

  • Correlate ranking shifts with Google updates

  • Export visual ranking reports

  • Add contextual notes to timeline events

This is your timeline-level view of keyword performance.


Why it matters

Rank numbers in isolation don’t tell the full story.

Historical Charts help you:

  • Diagnose ranking drops

  • Validate SEO improvements

  • Identify competitor movement

  • Understand market volatility

  • Provide clean visual reporting to clients

Without historical context, it’s difficult to interpret whether movement is normal fluctuation or a structural change.


Where to find it

  1. Navigate to a Project, Group, or Tag

  2. Locate your keyword in the Ranking Table

  3. Click the Chart icon next to the keyword


Ranking timeline

Once opened, the Historical Chart displays your keyword’s ranking over time.

You can select different time ranges, including:

  • 10 days

  • 30 days

  • 60 days

  • 90 days

  • 180 days

  • 1 year

  • 2 years

  • All time

This allows you to switch between short-term monitoring and long-term strategic analysis.


Competitor comparison

You can compare your keyword’s historical ranking against competitors.

Use the competitor dropdown inside the chart to select one or more domains.

This comparison helps you:

  • Identify when competitors overtook you

  • Understand whether drops were isolated or market-wide

  • Benchmark long-term positioning

For a full overview of competitor tools, see: Competitor Tracking in Google SERP.


Google update markers

Major Google algorithm updates are displayed directly on the chart timeline.

When you hover over an update marker, you’ll see:

  • Update name

  • Date

  • Link to official Google documentation

This helps you correlate ranking volatility with known algorithm changes.


SERP history

The SERP History tab allows you to view the Top 20/Top 100 search results for a keyword on a specific date. The depth depends on the day results were collected.

This is useful for:

  • Investigating ranking drops

  • Reviewing competitor presence

  • Understanding SERP composition at a specific moment


Ranking URL insights

You can click “Show Ranking URL” to see which URL ranked for the keyword on each date.

This is helpful if:

  • Different pages rank for the same keyword

  • URL changes impacted ranking performance

  • You want to analyze page-level behaviour over time


Maintain Continuous Rank (MCH) behaviour

If Maintain Continuous Rank (MCH) is enabled:

  • Chart gaps are visually connected

  • The system links the last confirmed rank to the next confirmed rank

⚠️ Important:

This does not mean the keyword ranked during missing days.
It only visually smooths the timeline.

For detailed explanation of MCH behaviour, see: Maintain Continuous History (MCH).


Adding notes to the timeline

You can add dated notes to document important events directly on your ranking timeline.

Notes are useful for:

  • Recording content updates

  • Logging technical SEO changes

  • Documenting Google algorithm impacts

  • Adding client-facing context


How to add a note

You can add notes from the Historical Chart

  1. Click on a specific data point in the chart

  2. Add your note in the text field

  3. Save

Once notes are added, you can see them on the Historical Chart and also in the Project Menu by clicking on the 3 dots.


Editing notes

  • From the 3 dot menu in the Project, click directly on the note text to edit it

  • Press Enter to save changes

To change the date:

  • Click on the note date

  • Select a new date from the calendar

  • Click Apply New Date


Deleting notes

  • Hover over the note

  • Click the “X” icon

  • Confirm deletion

⚠️ Important Behaviour:

Notes appear on the chart timeline at the selected date

Notes are tied to the project context


Exporting charts

You can export Historical Charts in multiple formats:

  • PNG

  • JPEG

  • PDF

  • SVG

Exports are useful for:

  • Client reporting

  • Internal documentation

  • Performance reviews


Best practices
