Ahrefs
ReplyDeleteWhile we’re on the topic of SEO, I wanted to mention Ahrefs. Ahrefs is a tool that allows you to do keyword research to ensure you’re targeting the best keywords with the highest traffic and lowest difficulty to rank for.
While this tool isn’t free or cheap, they do offer a free two-week trial. Alternatively, you can use their competitors like Moz or SEMrush (who also have free trials, hint hint). Whichever one you choose, if you’re serious about ranking on Google, I highly recommend a keyword research tool. Without them, you only have access to Google Keyword Planner, which doesn’t really help you find the right keywords.
