This tool is down for repair. Your patience is appreciated!
This Google domain rank checker gives you the top keywords for your entries. If you have an SEMrush account you have an API key. Look at the drop-down in the upper right when logged in. You’ll see a link for API and from that page click on profile. If you don’t have an SEMrush account, API keys are available for as little as $15. This module returns the organic search results data for your bulk Domain entries
Some ideas: Find what keywords are common– or absent– list of 15 domains covering similar topics . Maybe there are opportunities because only one of your competitors ranks for a particular word. Or, notice certain keyword phrases appear 10 times and make a note that these will be tough for you to rank on page one Google since you’re currently not there and the group you search for are more authoritative for the particular phrases.
DOMAINS should be formed as domain.com with one per line, DB is the country database as in SEMrush, LIMIT is the number of lines returned for each of the domains you enter, DELAY is the interval for each API call ping to the server (this is where spreadsheet APIs have problems: they ping ALL at once which is against the SEMrush TOS), DATE defaults to current. To set prior months, historic, use the 15th day of the month.
Look for the download button at the bottom of the page after submitting your bulk query. You want to look at these directly in a spreadsheet; let the newbies eyeball data results without sorting or filtering. All column headers are in the same order and have the same meaning as those on SEMrush.
