SERPWatcher's left column is packed with keyword positions data and some other handy features so you get the latest updates at first sight.
Keyword positions aren't the buzzword of rank checking anymore but they were the reason why it came into existence.
Keyword position changes, search volumes, and comparisons stuffed in one chart would be a mess. Switching between two easily readable charts makes more sense.
Time frames are for time comparison and Overview informs you about changes, the average, and the best positions.
The left column has a lot more to offer as a SERP rank checker. It starts with a filter to match your current needs, an option to add or create tags, or to delete keywords.
In case you need to export the keywords you can export a CSV file or copy them to clipboard.
