Speeding up "the whole site" is common but inefficient: some pages get almost no traffic, so time spent optimizing them doesn't pay off. It's more useful to first know which pages actually drive visits, then check what's slowing those down specifically.
What it does
Using traffic data from a site connected to Yandex Metrika, the skill finds the pages with the most search traffic, picks a mix of page types (homepage, category, product card), and measures their Core Web Vitals. It then builds a priority matrix: high traffic plus poor metrics means top priority; a fast page stays untouched regardless of traffic volume.
What you get
A table of page, visits, speed metrics and verdict, followed by a prioritized plan of 3 to 5 actions with expected reach — "speeds up every product card" rather than just one URL — plus a note on what not to bother fixing. This needs a Yandex Metrika connection to work; without it, the skill can't tell which pages carry real traffic in the first place. Run it whenever site speed needs work but there isn't budget to optimize every page.
