Keyword research is the bread and butter of any SEO campaign. You can’t have a SEO campaign without a defined list of primary and secondary keywords along with long and short tail keywords. It is so important that we don’t think that there is an SEO tool out there that does not have a keyword research tool in one form or the other. However, SEMRush’s keyword research tool is amongst the best.
Another feature of Ahrefs that could potentially help you take your campaign to even better heights is their content gap feature. It gives you the option to check which keywords your competitors are ranking for so you can stay one step ahead at all times. Basically speaking, Ahrefs gives SEOs the ability to overtake their competitors through knowing which keywords to target and focus on.
