Thai Bui: Hey guys, I notice some site title have several keywords listed like so: cool cat, smelly kat, kit kat | site.com
Does this help or hurt a site?
Luke Chaffey: As far as I know, it won't hurt a site & rather will help the theme & target of that page.
However, it could hurt from the POV of a consumer on Google looking at the listing.
If I saw lots of keywords in a title that a separated by commas I'd be thinking "that looks a bit sus".
Joseph Paulino: Sometimes when I see top 10 competitors are stable with their rankings using titles like in your example, I try to see exactly what they are doing and why they are doing it by studying their sites and do my best to connect the dots. More often than not it helped my rankings once I saw something that made sense and went for it. Just don't blindly do it because others are doing it.
Justin Y: Honestly I don't think it really helps from a user standpoint. It may help for some query spaces keyword wise but I wouldn't recommend doing it. Personally I think writing more meaningful/catchier titles and descriptions including the main keyword(s) is better for the CTR. If it were me, I wouldn't click on that title lol! That's my opinion.
Neil Hannam: I'd try and pick a single keyword to optimise each page for. Your keyword research should tell you which of those phrases are searched for most on an annual basis and a rough estimate of the number of other people targeting those words.
From there it's a case of picking that one keyword/phrase you chose to target based on the ratio of search volume to competition whilst taking into account the liklihood of you out ranking the current top sites for the terms you've selected.
This way you give users a clear and obvious title and you've a very focused page that has a clear optimisation strategy.
Thai Bui: Yea, I agree. From a user standpoint, it holds no value whatsoever. +Neil Hannam, makes a great point. I should focus on the target keyword and make a meaningful title rather than shoving keywords into the title tag. Now that I think about it, it's kind of lazy to implement this practice.
Thank you all for you feedback. Your input makes so much sense.
