Data updates within Sellics occur in different cycles for all the different features:
Profit - Live
This data is transmitted by Amazon's MWS API and is live.
Keyword Rankings - Daily / Flexible
The update cycle for keyword rankings depends on the total amount of keywords being tracked.
If less than 250 keywords are tracked, their rankings will be crawled on a daily basis.
After that the update cycles will steadily increase the more keywords are tracked.
Reviews - Daily / Weekly
For your "Top 100" products (by salesrank) Sellics will crawl all reviews on Amazon daily at night.
All other ("Monitored") products which were sold or created within the past 30 days will be tracked every 2-7 days, depending on their salesrank.
Prices, Salesranks, Buybox status - Daily
This data is retrieved daily at night via Amazon's API for all "Monitored Products".
Spy Sales - Daily
The Spy will crawl the stock levels and thus sales for all tracked products on a daily basis.
Product Texts (Title, Bulletpoints, Description) - Daily / After New Order
For all "Monitored Products" in the Cockpit and under Rankings this information is updated daily at night.
For the "Other Products", as well products in Profit and Inventory, this content will be updated as soon as Amazon's API transmits a new order.
Inventory - Daily
Inventory levels are updated live via the orders transmitted to the Profit dashbaord.
There can be minor synchronisation differences for uncompleted orders between Seller Central and Amazon's API though. The actual inventory level is transmitted via the API on a daily basis, so that these differences will constantly be corrected.
PPC Manager - Daily
The main data (ie. sales, costs & co.) is transmitted by Amazon's Advertising API on a daily basis for the day prior to today. This is also why you will never see PPC costs in the Profit dashboard when looking at "today".
New campagins will also appear on the next day - if they already generated impressions.
Changes in Keyword Structures (eg. moving Keywords between adgroups) and Bids should be synchronized each hour, at the latest though on a daily basis. It is recommended to make all changes within Sellics though, so that they appear within the Analyze section and Change Log.
Performance - Daily
This data is registered daily from the Seller Central business reports for the day prior to today.
Product Detector - Every 6 Months
This database is usually updated (crawled) every quarter of the year.
Due to highly complex restructuring work on a new international database, this has been postponed for quite some time now and will presumably be updated again in Q2 2018 in a new version.
