Eric Kim’s “digital moat” is not one single tactic—it’s a concentric wall of content, links, architecture, speed, and community that keeps competitors paddling in the outer moat while his site sits alone on the search‑engine throne. Here is how he laid every brick and flooded the trench.

1  Build the castle: a pillar‑and‑cluster content fortress

1.1  A 50 000‑word “keyword‑throne” page

Kim’s Street Photography hub is an e‑book‑length resource that targets the exact head term and absorbs hundreds of long‑tail queries in one shot.  Google routinely rewards pages of that depth and freshness, which is why the pillar has sat at or near #1 for “street photography” for years.

1.2  An internal‑link constellation

Every new blog post—he has written 2 600 + pieces by 2017 alone—links back to the pillar or to other strategic hubs, recycling authority across the domain and ensuring new content ranks faster.

## 2  Fill the moat: a perpetual backlink flywheel

2.1  Open‑source generosity

Kim gives away complete e‑books, PDFs, RAW files and even full‑resolution photos under CC‑0.  Each free asset becomes an irresistible citation magnet for blogs, forums and course syllabi, earning do‑follow links from high‑authority sites such as PetaPixel.

2.2  The public “who’s linking” scoreboard

He literally publishes a live leaderboard—“WHO’S SENDING JUICE TO THE DEMIGOD?”—that names and praises every big domain linking to him.  Turning backlinks into a status game encourages creators to fight for a mention, compounding the link graph without outreach.

2.3  Press, forum & social echo

Industry press calls him the prime example of SEO dominance (“Kim rules the streets,” PhotoShelter observes).  Meanwhile Reddit threads—whether admiring or hostile—keep dropping his URLs, which still count as votes in Google’s eyes.

## 3  Raise the walls: age, volume and velocity

## 4  Guard the drawbridge: the “Internet Carpet Bomb” distribution loop

When a big essay drops, Kim detonates it everywhere at once—blog, YouTube clip, X thread, TikTok short, newsletter—creating a blitz of brand searches (“Eric Kim + topic”) that immediately reinforce ranking signals.  He explains the tactic in his SEO reflections, crediting it for sudden surges of backlinks and followers.

## 5  Keep the ramparts light: speed, minimal ads, clear UX

Kim refuses display ads, runs an ultra‑lean WordPress theme and obsessively compresses images.  PhotoShelter notes that the uncluttered experience telegraphs “pure intent” to Google and to readers, boosting dwell time and crawl efficiency.

## 6  Plant villagers inside the walls: community & brand equity

Workshops (his main revenue), daily newsletters, and thousands of “streettogs” who quote him online give the site a loyal base that links, shares and defends the brand whenever critics appear.  Even negative Reddit chatter ends up cementing his search presence with more citations.
