An investor should not scale city landing pages or seller guides until page discovery, canonicalization, mobile usability, and internal links are understood. Use the following items as pass/fail checks.
In AuthoritySpecialist analysis (2026), over 70 percent of motivated sellers reach 'sell my house fast' sites on mobile, so run every check on a phone as well as a desktop.
City page and inventory crawlability
Evidence required: Inspect representative city landing pages ('sell my house fast' plus a city name), seller guides, the How It Works page, and any property or IDX pages in Google Search Console and a crawler.
Confirm what HTML is available, whether important content depends on blocked resources, and whether canonical directives match the intended indexable URL. Pass condition: Search engines can reach the intended public seller and city URLs, important page content is available after normal rendering, and the pages are not unintentionally blocked, canonicalized elsewhere, or isolated from internal navigation.
Fail condition: City pages or seller guides exist only inside an experience that is blocked, inaccessible to normal crawling, duplicated under conflicting URLs, or disconnected from the investor's crawl paths.
Severity: Critical when the main city and seller paths are systematically inaccessible; otherwise High. Owner: Technical SEO lead with the website developer. Corrective action: Fix crawl barriers, rendering dependencies, canonical conflicts, or URL routing at the template level.
Do not assume that moving content to a particular host or rendering method automatically creates ranking value. Validation step: Re-crawl the affected templates, inspect representative live URLs, and confirm the intended pages can be discovered and indexed without relying on a manual URL submission workflow.
Mobile seller experience and Core Web Vitals
Evidence required: Open the homepage, the main city pages, and the cash-offer form on a phone. Record PageSpeed Insights results for Largest Contentful Paint and Cumulative Layout Shift, and note whether the form, phone number, and process explanation can be used with one thumb.
Pass condition: A seller can read the offer process, tap to call, and submit the form on a phone without zooming, waiting on blocked content, or losing their place to layout shifts. Fail condition: The form is hard to complete on a small screen, buttons shift while the page loads, or the main content appears only after heavy scripts and images.
Severity: Critical when the cash-offer form cannot be completed on mobile; otherwise High. Owner: Website developer with the technical SEO lead. Corrective action: Simplify the mobile form, compress and defer noncritical images and scripts, reserve space for media, and keep the phone number visible in the mobile header.
Validation step: Retest on real devices and in PageSpeed Insights after deployment, then submit a test lead to confirm the form still delivers.
Structured data accuracy
Evidence required: Compare any LocalBusiness, RealEstateAgent, or organization structured data against visible page content, the service areas the business actually buys in, services such as cash home buying, and the vocabulary actually supported by the chosen schema type.
Use Schema.org and Validator.schema.org for syntax and vocabulary checks where appropriate. Pass condition: Structured data reflects visible facts, uses valid properties, and does not describe content or relationships that the page does not support.
Fail condition: Markup contains incorrect addresses, service areas the business does not buy in, unsupported properties, fabricated relationships, or data that conflicts with the visible page. Severity: Medium, or High when inaccurate markup affects material business, contact, or service-area information.
Owner: Technical SEO lead with the developer responsible for templates. Corrective action: Remove unsupported properties, synchronize structured data with the visible source of truth, and keep markup limited to facts the investor business can substantiate.
Validation step: Re-run validation after deployment and manually compare the rendered markup with the live page. Treat structured data as machine-readable context, not as a guaranteed rich-result or ranking mechanism.
XML sitemap and robots.txt quality
Evidence required: Compare submitted sitemap URLs with crawlable, canonical, indexable URLs, starting with the city landing pages and seller guides. Review whether stale, redirected, duplicate, or parameterized URLs are being submitted, and whether robots.txt keeps admin and internal investor-portal pages out of the crawl.
Pass condition: Sitemaps contain the canonical URLs the investor business actually wants search engines to discover and are regenerated when city pages or guides are added, merged, or retired. Fail condition: Sitemaps repeatedly submit retired city pages, noncanonical variants, blocked pages, admin or portal URLs, or URLs that redirect elsewhere.
Severity: High when the main city pages are missing or mixed with low-value URLs; Medium for isolated errors. Owner: Technical SEO lead with the CMS owner. Corrective action: Generate sitemap entries from the same canonical source used by the live site, remove URLs that are not intended for indexing, and block only the low-value admin and portal areas in robots.txt.
Validation step: Compare a fresh sitemap sample with the live crawl and Search Console index reports. Do not promise instant indexing or require real-time regeneration unless the underlying system genuinely supports it.
HTTPS and lead-form security
Evidence required: Check every public page and every form submission path for HTTPS, mixed-content warnings, certificate expiry, and redirects from HTTP versions. Sellers submit property addresses, phone numbers, and email addresses, so include thank-you pages and any third-party form or call-tracking scripts in the sample.
Pass condition: Every page and form loads over HTTPS without browser warnings, HTTP versions redirect to the canonical HTTPS URL, and the certificate renews before it expires. Fail condition: Any page shows a 'Not Secure' warning, the form posts over an insecure connection, mixed content breaks the padlock, or HTTP and HTTPS versions both remain indexable.
Severity: Critical when the cash-offer form or the main city pages show a security warning; otherwise High. Owner: Website developer with the hosting provider. Corrective action: Install or renew the certificate, force HTTPS redirects at the server level, replace insecure asset URLs, and confirm that form and call-tracking tools use secure endpoints.
Validation step: Re-crawl the site for HTTP URLs and mixed content, submit a test lead from a phone, and confirm the certificate expiry date is monitored so the warning cannot return unnoticed.
