Content and links get the attention, but technical SEO is the foundation underneath. It is the set of on-page and site-level signals that tell Google what a page is about, whether it can be indexed, and whether it deserves a rich result. Get these wrong and even great content struggles to rank.
eighty checks the signals that matter and, unlike a checklist, tells you which ones are actually failing on your site and what to do about each.
The checks that matter most
| Check | Why it matters |
|---|---|
| Title tag | The single strongest on-page signal and your search-result headline. |
| Meta description | Controls your snippet and click-through rate from Google. |
| H1 and headings | Give Google and readers a clear content structure. |
| Indexability | A stray noindex or robots block can hide you from Google entirely. |
| Canonical URL | Prevents duplicate-content confusion across URLs. |
| Structured data | Unlocks rich results (stars, FAQs, prices) in Google. |
| Open Graph tags | Clean previews when shared on social and WhatsApp. |
| Image alt text | Helps image search and accessibility. |
| Sitemap and robots.txt | Help Google find and crawl all your pages. |
Indexability: are you even in Google?
The most expensive SEO mistake is invisible: a leftover noindex tag or a robots.txt rule that blocks Googlebot. When that happens, none of your other work matters because the page is simply not in the index. eighty checks this first and flags it loudly, because it is the difference between ranking low and not ranking at all.
How to fix common SEO issues
- Title too short or missing: write a 30 to 60 character title with your main keyword first.
- No meta description: add a compelling 70 to 160 character summary so Google does not invent one.
- No H1: add one clear H1 with the page topic.
- No structured data: add Schema.org JSON-LD (LocalBusiness, Product, FAQ) for rich results.
- Missing alt text: describe every meaningful image.
Beyond SEO: the full picture
Rankings are not won on SEO alone. Google weighs page speed and rewards secure sites with strong security, and increasingly your audience finds you through AI like ChatGPT. eighty scores all four together so you fix the foundation, not just one corner of it.
