About seo tools
Practical SEO utilities for the mechanical parts of on-page work: generating meta tags and Open Graph markup, writing a robots.txt, building clean URL slugs and producing structured data.
The meta tag tools enforce the length limits that matter, because both ends are a real cost. Google truncates titles at roughly 600 pixels โ around 55-60 characters โ and descriptions at about 155-160. A title cut mid-phrase loses whatever differentiator you put at the end, which is usually the part that earns the click. A description of 70 characters wastes most of the space you were given.
Open Graph tags are worth more attention than they usually get, and the failure mode is invisible to you. Without them, a link shared to Slack, WhatsApp, LinkedIn or X renders as a bare URL or pulls an arbitrary image from the page. You never see this, because you are not the one sharing it. The one detail people miss most often: og:image must be an absolute URL, and a relative path silently produces no image at all.
On robots.txt, one correction that comes up constantly. Disallow prevents crawling, not indexing. A URL blocked in robots.txt can still appear in search results if other pages link to it โ Google simply cannot see its content to describe it. To keep a page out of the index, allow the crawl and serve a noindex directive. Blocking it in robots.txt actually prevents Google from ever seeing the noindex.
Frequently asked questions
How long should a title tag and meta description be?
Titles around 50-60 characters, since Google truncates near 600 pixels of width rather than a fixed character count. Descriptions around 140-160. Front-load the distinctive words in both, because the end is what gets cut.
Does a meta description affect rankings?
Not directly โ it has not been a ranking factor for many years. It affects click-through rate, which is worth optimising for on its own terms. Google also frequently rewrites descriptions using text from the page when it judges that a better match for the query.
Will robots.txt keep a page out of Google?
No, and this is a common and costly misunderstanding. Disallow blocks crawling, not indexing โ a blocked URL can still be listed if other pages link to it, just without a description. To exclude a page from the index, allow crawling and serve a noindex meta tag or header. If you block it in robots.txt, Google can never see the noindex.
Why doesn't my link preview show an image when shared?
Most often because og:image is a relative path. It must be an absolute URL including the protocol and domain. Also check that the image is publicly reachable without a login, and that it is large enough โ platforms generally want at least 1200x630.
