How to Check If Your Blog Has SEO Problems (Free Guide)
March 12, 2026 · 8 min read
Most blogs lose traffic because of invisible SEO problems. Not bad content — bad plumbing. After auditing dozens of real blogs, the same issues show up again and again. The good news? Most take 5 minutes to fix.
1. Check Your Title Tag
Right-click on your homepage → "View Page Source" → search for <title>.
What you want: A clear, descriptive title under 60 characters.
What I often find: Empty titles, titles that just say the site name, or titles stuffed with keywords nobody searches for. Your title tag is the single most important on-page SEO element — it's what shows up in Google search results.
Fix it: In WordPress, go to Settings → General → Site Title. With Yoast or Rank Math, set a custom SEO title for your homepage.
2. Check Your Meta Description
In the same page source, search for name="description".
What you want: A compelling 150-160 character summary that makes people want to click.
What I often find: No meta description at all, or one auto-generated from the first paragraph. Without one, Google generates its own snippet — and it usually picks poorly.
Fix it: Any SEO plugin lets you set a custom meta description for each page and post.
3. Check Your Open Graph Tags
Search the page source for og:title and og:image.
What you want: A proper title, description, and a high-quality image (at least 1200×630px) for every page.
What I often find:
- Missing OG images entirely
- OG images using HTTP instead of HTTPS (broken thumbnails when shared)
- SVG files as OG images (most social platforms can't display them)
- Multiple OG images conflicting with each other
When someone shares your blog post on Facebook, Twitter, or LinkedIn, these tags control what shows up. Bad OG tags = ugly preview = fewer clicks.
4. Check Your Heading Structure
Search the page source for <h1 and <h2.
What you want: Exactly one H1 per page (your post title), then H2s for sections, H3s for subsections.
What I often find: Multiple H1s, no H1 at all, or headings used for styling instead of structure. If your sidebar widget title is an H1 and your article title is an H2, you're confusing the algorithm.
5. Check Your Schema Markup
Search the page source for application/ld+json or schema.org.
What you want: At minimum, Article or BlogPosting schema on blog posts, WebSite schema on your homepage.
What I often find: No schema at all, or schema with the author set to "admin". Schema markup helps Google show rich results — star ratings, dates, author photos. Without it, your listing is plain text competing against rich results.
6. Check Your Twitter Cards
Search for twitter:card in your page source.
What you want: summary_large_image for blog posts (big image preview on X).
The difference between summary and summary_large_image is massive for engagement. Large images get more clicks. Period.
