Brand new keywords sound super tricky to find — except for a ton of easy ones that come around every January: simply adding the year to whatever keyword you’re targeting. People can start getting traffic from “2020” keywords long before they show up with any kind of search volume in typical keyword-research tools, since their data lags. (Hat tip to Glen Allsopp, who I got that idea from.)
The last time I looked Google displayed as many characters as it can fit into a block element that’s about 600px wide and doesn’t exceed 1 line of text (on desktop). So – THERE IS NO BEST PRACTICE AMOUNT OF CHARACTERS any SEO could lay down as exact best practice to GUARANTEE a title will display, in full in Google, at least, as the search snippet title, on every device. Ultimately – only the characters and words you use will determine if your entire page title will be seen in a Google search snippet.
At my comapny, Wpromote, we use this tool to help shape overall content strategies. Continuing with the dog food example, we can see that ratings, comparison, and reviews all were all grouped as closely related to dog food in general, implying that people that are searching for dog food are very interested in the comparison and review side of things. So from a content strategy perspective, it would be a very powerful takeaway to include a heavy emphasis on customer ratings, third-party reviews, and side by side comparisons to help the consumers make their dog food selections while shopping on our site.
Basically, SEO keyword research should be an ongoing and ever-evolving part of your job as a marketer. Old keywords need to be reevaluated periodically, and high-volume, competitive keywords (or “head” keywords, as opposed to long-tailed keywords) can often be usefully replaced or augmented with longer, more specific phrases designed not to bring in just any visitor but exactly the right visitors. (Who visits your site – particularly if they’re people who are actively looking for your services – is at least as important as how many people visit.)
