if cell contains chosen text, add value from another cell in same row

Hi
I have a sheet with 65,000 rows.
Column c contains text and numbers (phrases from search engine results seraches).
Column G contains the number of times the phrase was searched.

I am wanting to run a formula / macro which goes like;

If cell in column c contains variable then copy cell g out of same row to cell h. This way I can quickly sum up column h to see total number searches by variable

I have looked through forum for past half hour and could not find what i needed.

Thanks in advance anyone.
