Segmentation is the place to start :Business Strategy /Financial Advisors

As the saying goes, you don’t eat a whole elephant in one go. You eat it in
small bites. So break your influencer list into segments, to make it manageable.
Most firms take one of two approaches to segmentation:

& Splitting influencers by category, making separate lists of analysts,
journalists, consultants, regulators, etc. Depending on your categories,
and the numbers in each you may want to segment further, for instance,
breaking down consultants into top-tier, second-tier, niche and so on.
& Splitting influencers by importance. You may discover that, of your 50
or so top influencers, a dozen are substantially more important than the
rest, in which case it makes sense to focus on this select group. Again,
influencers are a scarce resource so spend your time with the ones that
will return most value.
Once you have a segmentation you’re happy with, you need to prioritise
your efforts. Clearly, if you have a segment of ‘VIPs’ – very influential
people – then start here. Look for groups of influencers that have relatively
greater influence where you need it. You may find, for example, that you
have as many journalists as channel partners in your list. So which group
has the greatest total influence? Which group will serve your firm’s greatest
need? Are you constrained by channel bottlenecks or are you being
ignored (or misrepresented) by the media?
Another aspect of segment prioritisation is the prior existence of any
relationship you have with influencers or influencer groups. Some firms
embarking on influencer marketing find that they get early and easy returns
just by focusing existing activity on newly-identified influencers. So by determining
the most influential journalists you can focus your PR programme only
on these selected few (and de-emphasising the rest). You can focus your AR
programme on the most influential firms for your target market, rather than
continuing the annual road show of 20 different analyst firms.
The existence of relationships with certain influencers may focus your
attention on these individuals for quick returns. Or you may decide to
leave your activities with these known influencers to current plans, and
invest primarily in those influencers that are new. It’s your choice, driven
by your firm’s greatest needs and opportunities.
