10 Technical Factors That Tank Your SEO Score
A low SEO score almost always comes down to a handful of recurring technical issues — most of them easy to fix once you know they’re there. Here are the 10 most common problems that drag down a score in an automated audit, and what to do about each one.
1. No HTTPS
A site still running on HTTP loses points immediately: Google has treated it as a ranking factor for years, and browsers now show a “not secure” warning that scares visitors away. The fix is usually simple (an SSL certificate through your host), but it needs to come with a 301 redirect from every HTTP URL to its HTTPS equivalent.
2. Missing, too-short, or too-long title tag
The title tag is one of the heaviest signals in an audit. A missing title is penalized, but a poorly sized one is nearly as costly: too short (under 30 characters), it wastes the space available in search results; too long (over 60 characters), Google truncates it. The realistic target is 50-60 characters, with the main keyword placed as early as possible.
3. Missing or badly sized meta description
The meta description has no direct ranking impact, but it strongly influences click-through rate from search results. A missing description leaves Google to generate an automatic snippet, often far less compelling. The ideal length is 140-160 characters.
4. Multiple H1 tags on one page
A page should have exactly one H1, summarizing its main topic. Having zero H1s or several confuses the content hierarchy for search engines. This is a common mistake on sites built with page builders (Divi, Elementor), where each section adds its own heading without checking which tag level is actually used.
5. Images without alt attributes
Every image missing an alt attribute costs points — for SEO (Google can’t understand what the image shows) and for accessibility (screen readers have nothing to announce). On an image-heavy page, this single factor can drag down a large share of the overall score.
6. Excessive load time
A slow load time hurts both user experience and SEO score — Google has built Core Web Vitals into its ranking algorithm for years. The most common causes: uncompressed images, too many third-party plugins/scripts, no caching, undersized hosting.
7. Missing viewport tag
Without a meta viewport tag, a page won’t adapt properly to mobile screens. With most web traffic now mobile and Google’s mobile-first indexing, a non-responsive page is structurally disadvantaged regardless of content quality.
8. No canonical tag
Without a canonical tag, a site risks duplicate content: multiple URLs (with or without www, with tracking parameters, HTTP/HTTPS versions) can point to identical content, splitting SEO value across several addresses instead of concentrating it on one.
9. Weak internal linking
A technical audit also looks at the number of internal and external links on a page. An isolated page, with no inbound links from other pages on the site, is harder for search engines to discover and inherits less authority. Solid internal linking helps both crawling and the distribution of link equity across pages.
10. No structured data (JSON-LD)
JSON-LD Schema.org markup doesn’t mechanically boost rankings, but it’s what enables rich results in Google (review stars, FAQs, breadcrumbs) and is an increasingly decisive factor in being cited by AI answer engines (ChatGPT, Perplexity, Gemini). Its absence is one of the most underestimated causes of a mediocre SEO score.
