A few days ago I decided to switch one of my campaigns from all broad match keywords to phrase match and a couple of exact match. Two of these keyword phrases in particular get a lot of searches a day but so far all the new narrow matched keyowrds just aren't getting many impressions at all. For example broad matched keyword1 keyword2 would generate around a 1000 clicks a day for me. From my stats I can see the vast majority of the hits are actually for keyword1 keyword2 and not variations, which is expected as it's a highly searched for term. But as soon as I changed it to [keyword1 keyword2] it hasn't got a single impression in three days. My minimum bid seems okay, so I can't work out my this is happening. Many other keyword phrases I switched to "keyword keyword" match are also not getting any impressions. These are also keyword phrases that were getting me a lot of clicks back when they were broad matched. I don't get it. I've gone from thousands of clicks a day to only getting around 20 or 30 yesterday.
There are several points that and you need to understand all very carefully. - When you simply change a keyword from broad match to exact match: keyword1 -> [keyword1] you: 1) Are forgiving the Quality Score History for the keyword keyword1 and creating a new quality Score History from scratch for [keyword1] 2) are also opting for a very restrictive method where the user can not see your ad if he type any variation of keyword1 in Google - for example if keyword1= "buy computer" only your competitor ads will show if someone type "buy a computer" or "buy computer now" I would give up from this migration and also begin to ask my self why you have to much impressions for these broad keywords How many negative keyword you have in your campaigns? In the example of the broad keyword: 'buy computer' your ad are also triggered for the follow searchs if you do not add the right negatives: buy computer games buy computer program buy computer advertisement buy a computer shop buy a used computer buy a computer course buy computer ebook buy computer magazine buy things with my computer and this hurts your Quality Score & Conversion Rate.
Good points Micromag and I do realise all of this. But as I said when I had keyword1 keyword2 as broad matched it was also showing my ad for just keyword1 searches, which I didn't want. Studying my stats I found that although broad match was giving me variations of the keyword1 keyword2 broad match, the vast majority of the clicks were for keyword1 keyword2. Again this is a highly searched for term so no surprises. So I change it to [keyword1 keyword2]. My min CPC appears to be the same, it says the keywords are active - yet not one single impression in three days. Does it mean each new keyword has to be approved by google? I've probably got around 30 or so negative words in the campaign.
