LRT shows you always real-time data. But if you upload a backlink list file, you cannot be always 100% sure that this file is up to date. To receive most recent data, we recommend the usage of GWT integration.
The upload is possible in DTOX and BLP, but the integration of Google Webmaster Tools to your LRT account is also beneficial for these 4 tools: CDTOX, CLA, LJR and LA. Benefits for you: most recent data in even more tools.
