When checking the backlink profiles many SEOs recommend ahrefs, majestic SEO and LinkResearchTools.
When comparing the three tools against each other they all return different types of metrics to analyse the quality.
Ahrefs has a DR (domain rank) and UR (URL rank) score that helps visualise quickly the power behind the backlinks.
Majestic has a TF (trust flow) and CF (citation flow) score to assist you.
LinkResearchTools has LRT trust and LRT risk to highlight the trustworthiness and risk element to the links.
In our opinion, all three tools are amazing to monitor the link building industry and we use all these within our companies.
