What is a brokerage website platform?

So here's what we're actually talking about when we say "real estate brokerage website platform" -- it's the technical system holding together your main brokerage site, every agent's sub-site, the MLS/IDX listing search, the lead-capture flow, and the editor experience that lets your brokerage team and each individual agent edit their own slice without nuking everything else. That's a lot of moving parts. At 50+ agents, you're facing a real fork in the road. You can go with a locked-in SaaS product -- Placester, Real Geeks, Sierra Interactive, BoomTown -- or you can build something custom on Next.js and Supabase with a proper IDX feed. Honestly, both paths make sense at different stages. SaaS gets you live in weeks. But it'll fight you every time you try to grow past the template. Here's the thing about custom builds: they're slower to launch -- sometimes by two or three months -- but they compound value in a way SaaS never will. Your SEO builds on your own domain. Your design isn't shared with 4,000 other brokerages. Your agents stay because the tools actually work. For brokerages past 100 agents, or anyone with serious brand requirements, custom wins on total cost of ownership, page performance, and -- this one surprises people -- agent retention. Agents notice when their site loads fast and looks good. They stay longer.

プロジェクトが失敗する理由

Look, Placester and Real Geeks aren't evil -- they're just built for speed-to-launch, not long-term performance And that tradeoff shows up in your Lighthouse scores. We're talking scores in the 40s. Pretty consistently. And slow pages don't just frustrate buyers -- they tank your local pack rankings. Competitors with faster sites are outranking your listings on searches for your own listing addresses. That's the part that should sting.
This is a genuinely unsolvable problem inside most SaaS platforms Either the platform locks everything down tight -- which looks great for brand consistency, but agents get frustrated and go build their own Wix sites -- or it opens everything up and you've got 87 different fonts and neon color schemes across your agent pages. Neither one scales past 50 agents without becoming a full-time brand enforcement job.
The IDX iframe situation is, honestly, one of the dirtiest secrets in real estate web development That search widget? It's not part of your site. Search engines see an iframe from a third-party domain and they don't credit any of that listing content to you. So you end up ranking for your brokerage name and almost nothing else. All those listings, all that content -- it's building authority for someone else's domain.
Agent churn is relentless in this industry And without the right tooling, every departure is a manual cleanup project. Their subsite, their bio, their phone number in the footer, their face on the team page -- all of it needs to come down. Miss one and you've got a former agent's contact form routing leads to someone who left six months ago. We've seen this exact scenario at a brokerage in Phoenix. It's a weekly fire, and it burns real hours.

コンプライアンス

Agent Subdomain Routing

Here's how the subdomain routing actually works: agentname.brokerage.com resolves through Next.js middleware, which looks up the agent record and serves their page -- all within a shared design system, on the same domain, with shared authority. Edge-rendered. Sub-100ms response times. And because it's one codebase, a design update rolls out to every agent page at once, not one-by-one.

MLS Feed as First-Class Content

Instead of an iframe phoning home to a third-party IDX server, listings live in your own database -- pulled via the RESO Web API and indexed in Algolia or Typesense. Every listing page is rendered as part of your actual site. So when Google crawls a listing at 123 Main Street, Austin TX, it credits that content to your brokerage domain. That's the SEO compounding effect SaaS platforms structurally can't replicate.

Role-Based Agent Editing

Agents get a scoped admin panel where they can edit their bio, upload gallery photos, pin featured listings, and manage testimonials. But they can't touch the nav, the footer, or anything flagged as brand-locked. Supabase row-level security enforces those boundaries at the database layer -- it's not just a UI restriction. And every edit is audit-logged, so if something goes wrong, you can see exactly who changed what and roll it back.

Automated Agent Offboarding

One command. That's it. When an agent leaves, their subsite switches to a graceful farewell state, their URLs 301-redirect to the team page, and their listings reassign to the brokerage. No manual cleanup, no orphaned contact forms, no 2am Slack messages from the broker wondering why a former agent is still showing up in Google. The whole offboarding flow runs in seconds.

構築する内容

Agent Subsites

Every agent gets their own full site -- whether that's a subdomain like sarahjones.brokerage.com or a subpath like brokerage.com/agents/sarah-jones. Either way, it's a real site with a bio, active listings, testimonials, and a lead form. Sarah can customize her content. She can't break the brand. That boundary is enforced in code, not just policy.

MLS/IDX Listing Search

We connect to the RESO Web API where the MLS supports it -- and most modern ones do -- or to a mid-tier provider like FlexMLS for older systems. Listings get indexed in Algolia, which means search queries return in under 100ms. The search UI includes map view, filters, saved searches, and email alerts. Not a widget. An actual product.

Listing Landing Pages

Every listing gets its own shareable page -- not a generic template printout, but a real page with proper OpenGraph images so it looks great when an agent shares it in an iMessage or posts it to Instagram. Virtual tour embeds, neighborhood context, QR codes ready for open-house flyers. This is the stuff agents actually brag about to their clients.

Lead Routing to CRM

Follow Up Boss, Lofty, BoomTown -- we've integrated with all of them. Two-way sync means leads hit the right agent instantly, with full UTM and referrer attribution, and agents can see lead status updates without bouncing between five different tabs. The real kicker is that the brokerage admin dashboard shows the same data, so nothing falls through the cracks.

City + Neighborhood Pages

Programmatic SEO -- done right -- means the brokerage owns "homes for sale in [neighborhood]" searches across every market you serve. We build city-level and neighborhood-level landing pages that are actually useful, not just keyword-stuffed boilerplate. Done at scale, this is how a Dallas or Denver brokerage takes real organic market share from Zillow and Realtor.com over 18-24 months.

Mobile-First Design System

Buyers search on their phones. Agents text listing links from their phones. So every page is designed phone-first, not desktop-first with a responsive afterthought. And we enforce a performance budget in CI -- if a new feature push degrades LCP past the threshold, the build fails. No sneaking in a heavy carousel at 11pm.

私たちのプロセス

01

Brokerage Architecture Workshop

Weeks one and two are about mapping reality before writing a single line of code. We document your current IDX feed, your CRM setup, your MLS provider, your actual agent count, and where you're planning to be in three years. You get an architecture doc, an integration plan, and a three-year cost model. Decisions made here save six figures later.
Week 1-2
02

Design System + Agent Template

Weeks three and four: design tokens for both the brokerage level and the agent level, a production-ready agent subsite template, and a listing detail page. Not mockups -- actual production code that the team can start stress-testing against real data.
Week 3-4
03

MLS/IDX Integration

Weeks five through seven are the integration sprint -- RESO Web API or FlexMLS/Spark depending on your MLS, Algolia indexing pipeline, image CDN setup, and the full listing search experience with filters and map. This is usually where the fun arguments happen about map clustering algorithms.
Week 5-7
04

CMS + Agent Admin

Weeks eight through ten: the two-tier editor UI, scoped role-based access control, audit logging, the agent onboarding and offboarding flows, and CRM two-way sync. By the end of week ten, a brand-new agent can be onboarded -- full subsite live -- in under ten minutes.
Week 8-10
05

Migration + Launch

Weeks eleven through fourteen are migration and launch. We export content from Placester or whatever you're leaving, map every old URL to its new destination with proper 301s, run SEO validation, and watch the launch like hawks. Then there's 30 days of post-launch support -- because something always needs tuning after real agents start using a real product.

よくある質問

エージェント向けサブドメインアーキテクチャはどのように機能しますか?

各エージェントはagentname.brokerage.com — 独自のページ、リスティング、問い合わせフォーム — を取得し、すべて1つのコードベース、1つのデザインシステム、1つのドメイン上で実行されます。技術的には、ワイルドカードDNSとNext.jsミドルウェアがサブドメインをデータベース内のエージェントレコードに解決します。約40ミリ秒かかります。SEOの観点から、メインドメインは継続的に権威を積み重ねます — エージェントサブドメインはそれを分割しません。これは多くの質問を受けることで、明確にする価値があります。

Real Geeks、IDX Brokerを置き換えることはできますか?

はい、Real GeeksやSierra Interactiveを置き換えることができます。これらのプラットフォームはIDXフィード問題を解決しますが、実際にCore Web Vitalsに失敗する遅い、テンプレートファーミングページに閉じ込めます。RESO Web APIを介してリスティングを直接適切なデータベースに取り込み、フルデザインコントロールでエッジファストレンダリングします。この切り替えを行った仲介会社 — ナッシュビルの1つを考えています — 通常、立ち上げから90日以内にLCPが40〜70%高速化し、ローカルランキングが2〜3倍向上します。

仲介会社向けプラットフォームのコストはいくらですか?

50〜150人のエージェントの場合、固定料金プロジェクトは通常$80K〜$220Kです。150〜500人のエージェントで複雑なMLS統合がある場合は、接続先に応じて$180K〜$500Kです。しかし、重要な比較があります:このスタックのホスティングはどのスケールでも年間$540〜$2,400で実行されます。Placesterスタイルのプラットフォームは月額$2K〜$8Kを請求します。3年間で、カスタムビルドは通常50〜70%低い総所有コスト — そしてあなたが資産を所有します。

エージェント向けの独自ウェブサイトがありますか?

はい — エージェントは実際にカスタマイズできる完全なサブドメインまたはサブパスサイトを取得します。プロフィール、ギャラリー、特集リスティング、お客様の声、問い合わせフォーム — すべて彼ら自身のものです。彼らが触れられないもの:仲介会社ブランド、ナビゲーション、フッター、法的免責事項。その境界はUIの隠しボタンではなく、データベースレイヤーのSupabase RLSを介して強制されます。すべての編集は監査ログされ、可逆的です。そしてエージェントが去るとき、オフボーディングは1つのコマンドで完了します。クリーンアップスプリントはありません。

MLS/IDXフィードはどのように処理しますか?

MLSがサポートしている場合、RESO Web APIに直接接続します — ほとんどの最新MLSはサポートしています。古いシステムの場合、ミッドティアプロバイダーを使用します:iHomeFinder、FlexMLS、またはSparkは、お客様のマーケットで利用可能な内容に応じて異なります。リスティングは15分ごとに同期され、画像はCDNエッジにキャッシュされ、検索はAlgoliaまたはTypesenseで100ms未満のクエリを実行します。ウィジェットではありません。実際の検索製品です。

ローカルSEOはどのように処理されますか?

実践的なSEOセットアップの実際のあり方を説明します:エージェント別のLocalBusinessスキーマ、関連するすべてのページのRealEstateAgentおよびRealEstateListingスキーマ、仲介会社とそれぞれのエージェントの主要市場の市区町村および近隣ランディングページ、GBP API統合によるレビュー、およびスケーリング用に構築されたプログラマティック近隣コンテンツテンプレート。シャーロットやサクラメントのようなマーケットの仲介会社がローカル検索を本当に支配し始める方法 — ただ表示されるだけでなく。

CRM(Follow Up Boss、Lofty、BoomTown)との統合はできますか?

はい、CRM統合は標準です。リード獲得フォームは完全なUTMと参照元属性を持つAPIを介してCRMにルーティングされます — どのページ、どのキャンペーン、どのエージェントリンクが各リードを駆動したかを正確に知ることができます。Follow Up BossとLoftyに対して双方向同期が利用可能です。つまり、エージェントは別のシステムにログインせずに仲介会社管理画面でリード状態の更新を確認します。属性は失われません。失われるまで、人々はそれがどれほど重要であるかを本当に気づきません。

リスティングランディングページはどうですか?

これは正直に言って、フラットなMLSフィードからの最大の差別化要因の1つです。すべてのリスティングには、適切なOpenGraphイメージを備えた独自の共有可能なランディングページが表示されます — エージェントがバイヤーにリンクをテキストで送信すると、実際に正しくプレビューされます。バーチャルツアーの埋め込み、近隣コンテキスト、リードフォーム、およびオープンハウスチラシ用のリスティングごとのQRコード生成。エージェントは単一の画面からオープンハウスマイクロサイトまたはメールキャンペーンをスピンアップできます。これはエージェントがどこに免許を掛けるかを友人に伝えるようにする種類のものです。
