Way to limit few urls per keyword

This could seem an odd question but i wanted to ask that if there is a way that we can use to have only few urls per keyword

i have a big list of keywords and what i see while scraping, is that for few keywords quite a many ( in thousands) urls are scraped and no url for many of my keywords.

i would want my scapings to be evenly distributed for all the keywords


Best Regards,
