Image optimization, minified CSS and JavaScript, server response time, use of CDNs, and eliminating render-blocking resources all contribute to faster mobile performance.
21. How do you optimize images for SEO?
Compress images with lossless tools, use descriptive file names and alt text, implement responsive images with srcset, and lazy-load offscreen images to improve LCP.
22. What is content cannibalization and how do you fix it?
Content cannibalization occurs when multiple pages target the same keyword. Consolidate or merge pages, apply 301 redirects, and ensure each page has distinct target keywords.
23. How do you conduct a technical log file analysis?
Analyze server logs to track crawler behavior. Identify crawl frequency, errors, and abandoned URLs. Use insights to optimize crawl budget and fix inaccessible pages.
24. What role does JavaScript play in SEO and how do you optimize it?
JavaScript can affect crawlability and rendering. Use server-side rendering or pre-rendering, defer non-critical scripts, and ensure critical content is in static HTML.
25. Describe the impact of page experience on SEO.
Google’s page experience signals include Core Web Vitals, mobile friendliness, HTTPS, and safe browsing. Optimize each to enhance user satisfaction and rankings.
26. How do you audit and clean up toxic backlinks?
Use backlink audit tools to identify spammy links by domain authority, relevance, and anchor text. Create a disavow file for persistent toxic links after attempted outreach removal.
27. What is link equity and how is it distributed?
Link equity (link juice) flows through internal and external links. Use strategic internal linking, 301 redirects, and nofollow attributes to channel equity to priority pages.
28. Explain siloing and topic clusters.
A silo structure organizes content into thematic groups. Central pillar pages link to cluster content, which in turn links back, strengthening relevance signals and improving site architecture.
29. What is crawl budget and how do you optimize it?
Crawl budget is the number of pages Googlebot crawls per day. Optimize by fixing server errors, removing low-value pages, and updating critical pages regularly.
30. How do you leverage Google Search Console for SEO?
Monitor index coverage, performance reports, and URL inspection. Identify and fix errors, track clicks and impressions, submit sitemaps, and analyze enhancement reports.
31. Explain orphan pages and their SEO impact.
Orphan pages have no internal links pointing to them, making them difficult to discover. Identify via crawl tools and link from relevant pages to integrate them into site structure.
32. What is HTTP/2 and how does it benefit SEO?
HTTP/2 supports multiplexing, header compression, and server push. These features reduce latency and improve load speeds, positively impacting user experience and rankings.
33. How do you implement automated SEO reporting?
