Don't know - it only me who experiences this or is it a common bahavior? My Excel lets only few queries in second to external services.
Some services are a bit faster, but everything by Google, like PageSpeed, AdWords or GSC are such lame ducks - i have really no enough patience to sit and wait, when i get, i.e. PageSpeed metrics for 1k urls...
And it isn't a subject of targeted urls - no matter what site i query, everywhere there are just some queries a second.
Are there any methods to speed up querying?
