Frequently Asked Questions
For a new website, Onsite SEO is significantly more important. In the early stages, your primary goal is to tell search engines exactly what your business is about and which keywords you are relevant for. Without clear onsite signals—such as optimized H1 tags, descriptive meta data, and a logical site hierarchy—search engines won't know where to categorize your site.
Furthermore, you cannot effectively build authority (Offsite) if you don't have high-quality content worth linking to. We recommend focusing 90% of your initial efforts on building a robust technical foundation and New websites, brand refreshes, and businesses with high-intent content that isn't ranking despite quality. pillars before aggressively pursuing offsite backlinks.
Offsite SEO can technically improve your domain authority even if your onsite SEO is lacking, but the results will be inefficient and likely won't lead to conversions. Think of Offsite SEO as a megaphone and Onsite SEO as your message. If your message is garbled or confusing (poor onsite), the megaphone (offsite) will just spread that confusion to more people.
You might see a temporary lift in rankings, but users will bounce quickly, and search engines will eventually realize your site doesn't satisfy the user's intent, leading to a decline in rankings over time. Always fix the message before buying the megaphone.
Onsite SEO typically yields faster results, often within weeks, as search engines re-crawl your site and recognize technical improvements or content updates. Changes to meta titles, internal linking, or site speed can have a measurable impact on rankings and click-through rates almost immediately. Offsite SEO is a longer-term play, typically taking 4-6 months to show significant impact.
Building genuine authority and earning high-quality backlinks is a gradual process, but the results are often more sustainable and provide a much larger 'moat' against competitors in the long run.
The ideal budget allocation depends on your site's current maturity. For most growth-stage companies, we recommend a 'Foundation First' approach. Initially, allocate 70-80% of your SEO budget to Onsite (technical audits, content creation, UX optimization).
Once your core pages are ranking on pages 2 or 3 of search results, shift your budget toward 60-70% Offsite (PR, outreach, brand building) to push those pages onto page 1. This ensures you are investing in authority only when your site is ready to convert the resulting traffic. Continuous monitoring of ROI will help you adjust these ratios as your market position evolves.
