Is this a potentially acceptable way to compare Google result quantities?

I’ve been recently trying to compare internet presence of a species to trend data I have collected. After reading a stack of papers on hit count estimates, I’m well aware that the number of results are, at best, an estimate.

My question is, how far off would it be to compare terms that produce drastic differences in the number of results? For instance:

“White-throated jay” OR “scientific name” yields roughly 7-14,00 results depending on the day/amount of time the query searches.

“Wandering albatross” OR “scientific name” yields roughly 50-60,000 results.

Is it safe to assume that there are more occurrences of the latter, despite the fluctuation? Thus, if I bracketed organisms based on their range (50k, 50-500k, 500k) they would be reasonably safe to compare?

Alternatively, does anyone know of another way/program to assess frequency of terms in internet media? I have tried a variety of online corpora but most of my species names return no results.
