Once I've identified such a site, I look at the total traffic, % that is referral, and then the top referrers (with percentages) on similarweb.com. This gives me sites that I can target for backlinks with indicative referral traffic (at least for the target I'm reviewing). The idea being that I should be able to prioritise to target sites that drive the highest levels of traffic and ultimately deliver some of that traffic to my site.
I also expect that my SEO will benefit from this campaign, as I'd hope that any sites delivering good volumes of relevant traffic should itself have good domain authority.
I am however coming unstuck a little when reviewing potential "role model" sites on SimilarWeb. An example is uluwatu.co.id; a clothing brand in Bali. According to SimilarWeb, ALL of their referral traffic is coming from a consumer electronics site. This; apart from not making any sense is also completely contradicted by other tools such as Alexa and Moz which show a much more believable list of backlinks.
My questions are; is SimilarWeb simply wrong and I shouldn't be relying on it? Is there another tool that will report % of referral traffic from each referrer?
