Browser extensions are important instruments for SEO. I take advantage of them day-after-day to save lots of time and improve productiveness.

I’ve addressed my favourite Chrome extensions for key phrases, authority, and analytics. What follows are my favorites for on-page auditing — to seek out errors, establish areas of enchancment, and analyze rivals. All are free.

Hyperlink Checkers

Free Backlink Checker is obtainable for Chrome and Firefox. This free extension scans a web page for hyperlinks and generates a report containing:

• Inner and exterior hyperlinks,
• Anchor textual content for every hyperlink,
• Goal root area of every hyperlink,
• Hyperlink standing (damaged, unverified),
• Nofollow attributes.

I take advantage of Free Backlink Checker to extract all hyperlinks and export into Excel for extra evaluation, similar to sorting by area and header standing. The extension additionally exhibits the HTML code of any hyperlink when hovering over it.

Damaged Hyperlink Checker is another choice. It, too, is obtainable for Chrome and Firefox.

I sometimes use a net crawler to seek out damaged hyperlinks. However a crawler doesn’t establish a particular hyperlink — solely the web page — making it difficult to seek out and repair, particularly when the hyperlink sits in an enormous navigation menu.

Browser-based hyperlink checkers make it a lot simpler by color-coding on-page hyperlinks based mostly on their standing.

Damaged Hyperlink Checker runs its report by default when a web page hundreds, which to me is extreme. Examine My Hyperlinks, one other Chrome extension, runs solely when its icon is clicked within the tackle bar. It additionally color-codes redirects, which, like damaged hyperlinks, ought to be fastened.

Key phrase Highlighters

To establish key phrases on a web page, I favor Spotlight Magic for Chrome and Multi-Key phrases Highlighter for Firefox.

Desktop browsers will spotlight specified key phrases on a web page utilizing Ctrl+F (PC) or CMD+F (Mac). However there’s no simple solution to differentiate variations of phrases (plural vs. singular) or phrases with various phrase sequences (“the blue shirt” vs. “the shirt is blue”).

Spotlight Magic and Multi-Key phrases Highlighter each verify differing phrases and mixtures — all recognized with distinctive colours. It’s helpful for recognizing over-optimization, similar to utilizing too most of the identical key phrases (standalone or in phrases), and for analyzing rivals’ priorities.

Textual content Optimizing

TextOptimizer is obtainable for Chrome. The extension analyzes a web page, extracts the first key phrase, and suggests associated ideas to enhance relevancy for a focused search question.

TextOptimizer assigns an total rating, which I don’t concentrate on. However I regularly use the ideas to enhance a web page’s rating for a subject.

Nofollow Highlighters

NoFollow, an extension, has Chrome and Firefox variations. It highlights nofollow hyperlinks on any web page, useful for monitoring inner and exterior hyperlink fairness and detecting mistaken nofollow attributes.

NoFollow is particularly helpful for older web sites that use the now ineffective “PageRank sculpting” and for older WordPress plugins that used the tactic.

Nevertheless, solely NoFollow’s Firefox model checks for nofollow meta tags. To verify in Chrome, attempt Hyperlink Redirect Hint, one other extension, which additionally tracks indexation standing and Robots.txt crawl errors.

There’s no “operating” NoFollow and Hyperlink Redirect Hint. Each mechanically spotlight nofollow hyperlinks on a web page when loaded in a browser.

Structured Knowledge Validators

Ryte structured information helper is a Chrome extension. I typically use it to verify the structured information of wealthy snippets in natural search outcomes. I then copy-paste the markup into the Schema.org validator to grasp the implementation.
