I need to change my title tag, I think this will raise my CTR. So I have a 6 words title tag, I'm planning to add 3 more words (the first 6 words will stay the same). The content will stay the same for now. This is a heavy linked page (4-5000 backlinks). I'm ranking very well in Google for the first two words on my title tag, I just need higher CTR. Do you think my rankings will stay the same if I add three more words? Do you believe in the dilution story? Please help, I will let you know what happens.
The best idea is to try it. See what happends. I think that the new keywords you target might increase your overall traffic. The title tag is sjut a small part of SEO so even if the dilution story is true it shouldnt have a huge effect.
You should be fine. Making a small change like that shouldn't destroy your rankings. i would just keep an eye on it if you are worried.
It really depends. If you have a lot of good quality backlinks with the right anchor texts for your six existing keywords, I don't expect much change in ranking if you add 3 more. Also, competition has something to do with it. If you don't have a lot of backlinks with the right keywords in the anchor text and the competition is strong, your ranking can be affected. From my experience, the number of keywords has a lot to do with ranking.
