Historical Data module in SEO SpyGlass allows you to tap into the historical index for your site and competitors to:
and many more!
To start researching, jump to Historical Data in the lefthand sidebar.
Type in the domain or specific webpage URL you'd like to research.
Choose the corresponding search mode - it can be set to domain and subdomains, domain only or exact URL.
Hit the Search button and allow a few moments for the app to harvest the data.
Once the search is complete, you'll get to the Backlinks sub-module. At the top, you'll see the History graph reflecting the changes to the backlink profile of the domain/webpage researched.
Focus on any date / date range within the last year to make thoughtful adjustments to your SEO strategy based on the results.
Right on the graph, click twice on any brick to select that specific date, or click > drag > click to select the period.
The workspace below will then list the links gained or lost on a certain date / within the selected period only.
Alternatively, use the Calendar right in the workspace - type in the dates manually, choose a predefined period or select a custom range (same way, click > drag > click).
Switch to New links to explore the links that were gained (first found) within the chosen period.
At a glance, evaluate the authority of the linking pages/domains, revise the link types and anchor details. See which links are a valuable addition to your profile and which ones seem out of place.
Go to Lost backlinks to see which ones were lost for whatever reason within the chosen period. Use the predefined workspace filter to switch between the removal reasons:
Revising the lost links in tandem with the reasons is a great aid in:
The workspace is customizable to let you revise the factors you are interested in. Upon going to the workspace editing menu, you can add or hide any columns.
Additionally, you can set up custom filters to sort out the data based on any factor (for instance, filter out the newly-gained backlinks coming from low-authority pages) or a combination of factors.
After you have adjusted the period, revised the data and filtered out the records worth a closer look - export the results from your project for any further manipulations.
Switch to the Linking Domains sub-module to revise the new and lost linking domains.
Check with the History graph to spot any drastic changes at any point. Scroll the graph or switch between the visualized periods the same way as in the Backlinks sub-module.
Choose any date or date range to see the detailed stats in the workspace below. On-hover, unfold the list of links for any domain in the table.
Below you can see how you can investigate a dropdown (select the date), then spot the domain you've lost the most backlinks from (sort the records by the # of Backlinks column), and see the specific links lost.
To investigate the reasons, hit the View All button - the app will analyze the given domain closely and will show the causes of losing each link.
Under Backlink Profile > Summary, you can find an interactive report showing profile development over time.
You can hover over any of the charts and move along to see how the changes correlate.
Below the graphs, you can see the stats for the New / Lost Backlinks and Domains for the last 30-day period, with a few link examples (either the top ones by InLink Rank or the most recent ones).
In the Enterprise edition, you can export the Summary report with the Quick PDF Export button at the top right corner.
To run brand new research with the other search settings or for another domain/page, simply adjust the settings anew and hit Search.
