What is Link Velocity?
Link velocity is an SEO metric that measures the rate at which a site acquires new backlinks. It is calculated over a specific period. This is typically over a few days, weeks, or months.
Search engines use the link velocity metric to evaluate the naturalness of a site’s backlink profile. A sudden increase in a site’s link velocity could raise suspicion and may indicate the blogger or SEO is engaged in unnatural link-building techniques.
There are considerations that link velocity is a Google ranking factor. Some SEOs also believe a sudden increase in link velocity may cause Google to lower your rankings. This has remained unconfirmed so far.
