UNDERSTAND THE FOUNDATION
What Is Technical SEO?
Technical SEO makes your website easier for search engines to access, understand and index, and easier for people to use.
It connects crawling, site architecture, page speed, mobile rendering and structured data. Content tells your story. Technical SEO helps make that story accessible.
- 01 · DiscoverLinks and sitemaps reveal your pages.
- 02 · CrawlSearch engines access and render the content.
- 03 · IndexEligible pages can enter the search index.
- 04 · ServeRelevant indexed pages may appear in results.
WHY IT MATTERS
Small technical barriers. Real business consequences.
Visitors lost to friction
Slow loading, unstable layouts and awkward mobile journeys can interrupt an enquiry or purchase.
Remove unnecessary friction between interest and action.
Content held back
New content and earned links have less opportunity to help when the underlying pages cannot be accessed reliably.
Give your existing marketing work a sound foundation.

CLEAR ANSWERS
Technical SEO Questions, Answered
What does a technical SEO audit include?
A technical SEO audit reviews crawlability, indexation, rendering, redirects, canonical URLs, sitemaps, internal links, structured data and performance. You receive prioritized findings, recommended fixes and an implementation scope with a way to validate the work.
How is technical SEO different from on-page SEO?
Technical SEO focuses on how a site is accessed and functions. On-page SEO focuses on the structure and relevance of individual pages. They overlap in areas such as headings, internal links and image optimisation.
How much do technical SEO services cost?
Monthly SEO plans include technical SEO and start at $1,199 USD. The technical scope varies by tier and website complexity. Focused standalone tasks start at $500 USD; larger audits and implementation projects are quoted separately. See the pricing section for monthly ranges.
How long does it take to see results?
Timing depends on implementation, recrawling, the original issue and market competition. Some technical changes can be verified quickly; search and business outcomes need ongoing measurement. The case studies above cover five- and six-month campaigns, not promised timelines.
Will you implement the fixes or only provide an audit?
We can scope implementation as well as diagnosis. Before work begins, we agree which changes Core Stackr will deliver, which need your developer or platform provider, and how each change will be tested.
What are Core Web Vitals?
LCP measures loading, INP measures responsiveness and CLS measures visual stability. We use these alongside the wider user experience. Passing the metrics alone does not guarantee strong rankings.
Does every website need crawl-budget optimisation?
No. It is most relevant to large or rapidly changing websites. Smaller sites often benefit more from resolving access issues, strengthening useful content and fixing important internal links.
Can you support ecommerce, international sites or migrations?
Yes. The scope can include faceted navigation, large product catalogues, international URL structures, hreflang and migration planning. Recommendations depend on your platform and how customers use the site.
Does structured data guarantee rich results or AI citations?
No. Relevant markup helps describe visible content and may support eligibility for applicable features. Search engines determine whether those features appear; schema does not guarantee a ranking or AI citation.
Do I need an llms.txt file for AI search?
llms.txt is an optional resource for AI tools that choose to read it. Google does not require it for AI Overviews or AI Mode. It does not replace accessible content, crawler controls or sitemaps, and cannot guarantee AI discovery.
How do you measure technical SEO progress?
We establish a baseline, validate completed fixes and monitor relevant indexation, performance and search data. When tracking is available, we also review qualified enquiries or conversions rather than treating technical scores as the final business outcome.
Can technical SEO guarantee first place?
No. Technical quality supports visibility, but rankings also depend on relevance, content, authority, competition and search systems. Our commitment is to sound implementation, clear measurement and continued improvement.
