The case for going elsewhere
Your own site can assert things; other sites corroborate them. Since corroboration is what turns a claim into a fact a model will repeat, being present where others already read is a legitimate part of the work.
Don’t duplicate your best pages
Republishing an article verbatim on a larger platform frequently means their copy is the one cited, because their domain carries more weight. You have then paid to make someone else the source for your own thinking.
Syndicating your best page can make someone else the citation for your own argument.
Publish adjacent, not identical
Write something that stands alone for that audience and points to the fuller treatment on your site. You get the mention and the description; the canonical depth stays where you control it.
Prioritise places that describe you accurately
The value is in being characterised correctly at a credible source. A specialist publication describing what you do precisely is worth more than a general platform where you appear as an anonymous byline — and inaccurate descriptions elsewhere are exactly what you later have to chase down and correct.
Own the profile pages you can
Directory listings, association memberships, and marketplace profiles are quick wins because you control the text. Making them agree word-for-word with your site is the consistency that engines reward.
Judge it by description, not reach
The metric is not audience size but whether the resulting text describes you the way you would. Check it the way you check anything else — against your fixed prompt set, monthly.
