Just about all web optimization instruments make the most of scraped search outcomes. To get extra insights from every scrape, and thus decrease prices for the tip consumer, instruments generally use this parameter to power expanded search outcomes to seem on the primary web page as a substitute of the standard 10 common natural search outcomes that customers see by default. For instance, Moz Professional has lengthy standardized on &num=50, which provides you 5 “pages” of outcomes per scrape.
This parameter was really deprecated a few years in the past, however continued to be unofficially supported. By mid-September, web optimization instruments had steadily stopped working, forcing us to search for alternate options. Some instruments, akin to Moz and STAT, present an alternate known as “stitching”, which stitches collectively a set of paginated outcomes, 10 at a time, into one lengthy consequence set. There are numerous issues with this strategy, a lot of which might be mitigated or prevented, however the principle implication is price, which finally ends up being considerably increased and sometimes unsustainable.
This also needs to be seen within the context that SERP knowledge prices have typically elevated in recent times, as instruments are pressured to increasingly carefully mimic actual browsers with the intention to get hold of correct and consultant rankings.
