Instagram Scores 100 on Authority. The Cafe Down the Street Scores 9.

Three things one small audit turned up, the kind that actually change what you do next, not just interesting trivia.

1. Domain authority tells you where to actually spend effort

Checked the authority score of everything ranking for a client's target keywords. Instagram and Tripadvisor sat near 100. Every individual competitor's own website scored under 10. Exact numbers shift depending on which tool measures them, Moz, Ahrefs, and SEMrush each run their own version, but the pattern holds across all three: benchmark analysis compiled by Linkscope puts the average score for a first-position Google result around 68. Trying to out-rank Instagram at that gap is a losing game. Out-ranking another small business's homepage, sitting at single digits, is a fight that's actually winnable. One number, and it completely reordered the priority list.

2. I don't trust a single search, and neither should you

Checked the same keyword twice, same tool, same rough location, a few days apart. Got two different difficulty scores. Turns out that's a known quirk of these tools, not a glitch specific to me. SUSO Digital's write-up on keyword difficulty uses exactly this example to make the point: the same keyword can show a difficulty of 21 on one tool and 37 on another, simply because each one weighs its inputs differently. The scores aren't wrong, they're estimates built on shifting inputs. The lesson isn't "the data is bad," it's that any one search is a snapshot, not a verdict. Before I tell a client a keyword is winnable, I check it more than once.

3. Splitting copy into invisible and visible made cross-team work painless

Every piece of SEO copy fell into one of two buckets: invisible (meta tags, schema markup, alt text, nobody reads it, it only talks to Google) or visible (headlines, About sections, the stuff people actually read). SEO Geek draws a similar line: one side of the work decides whether a search engine can access and interpret a page at all, the other decides whether that page earns its place once it's found. Working alongside a brand strategist on the same project, keeping the two separate meant there was almost nothing to argue about. She owned the column people read. I owned the column Google reads.

None of these were clever tricks. They were just the difference between guessing and checking.

None of this means every business needs its own site. Plenty of small, local operations do fine on Instagram and word of mouth alone, borrowing a platform's authority is a reasonable trade if that's as far as the ambition goes. It stops being enough when there's a specific problem only a website can fix. A line of code telling Google "this is a distinct business, not the other one with a similar name" has nowhere to live on a social profile. Neither does the intent behind someone typing a search into Google, which is a different crowd from someone scrolling Instagram.
