Step-by-Step Guide to Improve SEO Score with SEO Site Checker

Introduction

An SEO score is a snapshot of how well your site follows SEO best practices. Improving that score doesn't only make your site "look good" in reports. It improves visibility, user experience, and organic conversions. In this guide you'll get a repeatable, step-by-step process that uses free, beginner-friendly tools from SEO Site Checker to find problems, prioritize fixes, and measure progress.

Why your SEO score matters

Your SEO score aggregates signals across technical health, on-page optimization, performance, and backlinks. A better score usually means:

• Faster page loads and improved mobile UX
• Clear signals to search engines about content relevance
• Fewer crawl/index issues that block ranking
• Higher click-through rates from search results

Think of the score as a prioritization map: it directs you to the highest-impact problems first so you can spend time where it matters.

How SEO Site Checker works (overview)

SEO Site Checker runs automated scans across core categories:

• Technical: page speed, mobile friendliness, HTTPS, crawlability.
• On-page: title tags, meta descriptions, headings, image alt text.
• Content: relevance, keyword usage, readability, structured data.
• Links & authority: internal link structure and backlink signals.

Run a free scan at the Website SEO Score Checker to get a baseline score and a categorized list of issues you can fix right away.

Step 1 - Get a baseline audit

Before you change anything, run a complete scan to capture the current state. Use SEO Site Checker’s free audit (no signup required) to export a report that shows:

• Overall SEO score
• Technical errors and warnings
• On-page issues (missing titles, duplicate metas)
• Performance metrics (page load times, image sizes)

Save this report, it becomes your baseline to compare against after you make fixes.

Step 2 - Fix high-impact on-page SEO issues

On-page changes are often the fastest way to raise your score and improve rankings. Work through the items below in priority order.

Title tags & meta descriptions

Optimize your title tags to be descriptive, include the target keyword near the front, and keep them under ~60 characters so they show properly in search results. Meta descriptions should summarize the page and include a convincing call to action. Keep these under ~155 characters.

Tip: Use the Meta Tag Analyzer to preview and test title/meta length and recommendations.

Header tags & content structure

Use a single H1 per page, then H2/H3 to build logical sections. Break paragraphs into short chunks, use bullet lists for scannability, and ensure headings reflect the page’s topic hierarchy.

Keyword usage & LSI terms

Include your main keyword naturally in the first 100 words, the H1, and in at least one H2. Sprinkle related (LSI/NLP) terms across the content to help search engines understand context without keyword stuffing.

Image optimization & alt text

Compress images (use the Image Compressor), serve next-gen formats where possible (WebP), and add descriptive alt text that includes relevant keywords when appropriate.

Internal linking & anchor text

Link relevant pages to each other using descriptive anchor text. This helps spread link equity and makes discovery easier for both users and crawlers. Prioritize linking to cornerstone content and product/service pages.

Content quality & user intent

Write to satisfy the user's intent. If searchers expect a how-to guide, deliver step-by-step instruction and examples. Use authoritative citations, answer common questions, and include original insights to boost E-E-A-T (Experience, Expertise, Authority, Trust).

Step 3 - Refresh and expand content

Older posts are easy wins. Update facts, add examples, improve headlines and add internal links to newer, related posts. Use analytics to find pages with high impressions but low CTR — rewrite titles and meta descriptions to improve click-through rates.

Step 4 - Solve core technical SEO issues

Technical issues are often blockers. Use the audit report to prioritize fixes that block crawling, indexing, or performance.

Site speed & performance

Page speed is a major ranking factor. Key fixes include:

• Enable caching (server or CDN)
• Minify and defer non-critical JS and CSS
• Use image compression and lazy loading
• Use a lightweight theme or front-end framework

SEO Site Checker highlights slow pages and recommends specific improvements in the performance section of the audit.

Mobile & responsive design

Google indexes sites mobile-first. Make sure fonts, buttons, and layouts work on smaller screens. Test pages using Google’s Mobile-Friendly test (link to official tool) or check mobile results in the SEO Site Checker audit.

Crawlability & indexation

Verify your robots.txt and XML sitemap. Use canonical tags to prevent duplicate content issues and fix broken links or soft 404s. If pages are unintentionally set to noindex, they won’t appear in search results, remove that flag where you want visibility.

Structured data & schema

Add structured data where it makes sense (Article, BreadcrumbList, FAQPage) to enable rich results. Use JSON-LD format and validate with Google’s Rich Results Test.

HTTPS & security

Always serve your site over HTTPS. Mixed content warnings, expired certificates, or insecure resources can reduce user trust and trigger search engine problems.

Step 5 - Off-page SEO & backlink strategy

Backlinks remain a core ranking signal. Focus on quality over quantity.

Earn high-quality backlinks

Prioritize links from relevant, high-authority sites in your niche. Tactics that work include guest posts, data-driven studies, resource pages, and partnerships. Avoid paid or spammy link networks, they can do more harm than good.

Monitor brand mentions

Use alerts to find unlinked mentions and politely request a link. Convert brand mentions into backlinks when appropriate.

Clean up toxic links

If you have spammy backlinks, try outreach to request removal. If removal fails, use Google’s disavow tool sparingly and carefully.

Step 6 - Monitor, analyze, and iterate

SEO is cyclical. Track improvements, re-scan with SEO Site Checker, and compare reports to your baseline.

Track KPIs

Core KPIs include organic sessions, ranking (positions) for target keywords, impressions, CTR, and pages indexed. Tie SEO improvements to real business outcomes (leads, sales) where possible.

Use Google Search Console & Analytics

Integrate audit findings with Search Console data to identify pages with high impressions but low CTR or pages losing impressions. Use this data to prioritize title/meta tweaks and content updates.

Test changes

Make one change at a time (title tweak, content expansion) and monitor results over a multi-week period. SEO changes take time to show measurable impact, but careful tracking reveals what works.

Common mistakes to avoid

• Chasing a perfect score instead of real user experience improvements.
• Keyword stuffing or adding irrelevant content to hit an algorithm.
• Ignoring mobile users or failing to fix crawl errors.
• Not prioritizing fixes by impact and effort.

Always prioritize user intent and business outcomes over vanity metrics.

Conclusion & next steps

Improving your SEO score is a combination of careful audits, prioritized fixes, content improvements, and consistent monitoring. Start with a baseline scan using the Website SEO Score Checker, fix high-impact on-page and technical issues, and then move to content and link building. Re-scan regularly and use analytics to verify the impact.
