Someone half way joked about Google not liking the word "free" in another thread. May be quite true. I have a subtle section in my website on figures of speech in the bible, only found via my links page at the end, or in the search engine of my advice page. Due to my site's nature, I don't put it out front. But Wikipedia sends a lot of traffic in the back door. Anyway, I was getting these darn ads displayed for ACTION "FIGURES" due to the many used of "figures" in figures of speech. It took some work to change a lot of "figures" to singular "figure" and increase other text like "bible" or "scripture". So, it took about two hours of writing, changing and reloading the page to see relevant ads come up. One weird one happened this week. I have a page on 19 signs of hazard trees. Noticed that it escaped me adding Adsense - so I did. The first ads to show were on "viral" medicines and health stuff. So I asked myself "what repetitive text is doing this?" So happens, that when I tweaked the page for arborists to use the article for online Continuing Education Units - CEUs - I added the word "REMEDIES" at the request of the program coordinator, since he asked me to include remedies to deal with the hazards. So I went in and changed "remedies" to "solutions" and other choices. Within a half hour, tree and garden related ads showed up as desired. So "FREE" may trigger certain ads - maybe low paying ones: seriously.
He he that was not Joke , i said true Google don't like "FREE" the main reason if the Adwords advertiser giving any service as free sure he will advertise that site with $0.01 per click.
Very true. You have to be carefull what words you use on site with adsense or someone will smart price your site.
if i were you, i only continue to work. if you are honest to google adsense and google search, nothink will happen to you and you will continue to earn
Yes, but it means lower corresponding RPC for you. People who come to your site for free things aren't likely to spend money on what the advertiser sells.
I have to say when I do adword campaign, putting free as a negative keyword increases my conversion rates.
Looks like the topic is worth a revisit. I dropped out of the loop a bit lately. But about your question, I would suspect that there are words that could work too well - too well in the sense of getting your page loaded up on screen a lot, with many impressions, but very few clicks. It's the reverse side of the coin that brought this to mind, in the days when I bid on and had my ads displayed. "Tree Removal" brought a huge surge of my ad being displayed on pages, but I noticed that it was after Christmas. People were not searching to have landscape trees removed, they were searching to get their old Christmas trees removed. In that case "tree removal" worked too good and for the wrong reason for me. So I suspect that the same concept could apply for people displaying Google ads on their site.
I just counted the number of times "free" appears on my blog and it's 28 . Maybe I should rephrase some articles and see if I get any improvement in eCPM.
