If you're new to Ahrefs and want to run your first SEO audit, the fastest path is: open Site Explorer, enter your target URL, review the Overview for a health snapshot, then dig into Organic Keywords, Top Pages, and Site Audit to find specific problems. From there, build a short prioritized to-do list instead of trying to fix everything at once.

This tutorial walks through that workflow using a realistic starting scenario, explains what the numbers mean, and shows how to turn findings into actions.

Before You Start: Pick a Narrow Scope

A common beginner mistake is auditing an entire large website on day one. The reports become overwhelming, and you can't tell which issues matter.

Instead, choose one of these starting points:

• A single important page (your homepage or a key product/service page)
• A small site (under ~50 pages, e.g., a personal blog or small business site)
• One section of a bigger site (e.g., /blog/)

For this tutorial, assume you're auditing a small business site with about 30 pages. The same steps scale up later.

You'll need an Ahrefs account to follow along. Ahrefs offers paid plans, and pricing and feature limits change over time, so check the current Pricing page for what's included in each tier before committing.

Step 1: Enter Your Target in Site Explorer

Site Explorer is Ahrefs' core tool for analyzing any website or URL.

1. Open Site Explorer from the top navigation.
2. In the search box, paste your domain (e.g., example.com).
3. Choose the Exact URL or Domain mode depending on scope. For a full-site view, use Domain or Prefix; for a single page, use Exact URL.
4. Press Enter.

You'll land on the Overview report. Don't try to absorb everything — focus on four numbers first.

Reading the Overview Snapshot

Important caveat: Ahrefs' traffic and keyword numbers are estimates based on its own data. They won't match Google Search Console or your analytics exactly. Treat them as directional, not absolute.

Step 2: See What You Already Rank For

Go to Organic Keywords in the left sidebar. This shows queries where your site appears in search results.

Sort by Traffic (descending) to see which pages bring the most estimated visitors. Then look for:

• Keywords ranking in positions 4–15 — these are often the easiest wins. A small content or on-page improvement can push them onto page one.
• Keywords with high volume but low position — potential opportunities if the topic is relevant.
• Irrelevant keywords — if you rank for something off-topic, it may signal thin or mismatched content.

Write down 5–10 of the position 4–15 keywords. These become your first optimization targets.

Step 3: Find Your Best and Weakest Pages

Open Top Pages. This ranks your URLs by estimated organic traffic.

Look for two things:

1. Your top performers — understand what topics and formats work. Can you create more content like this?
2. Pages with traffic but poor rankings — these may need on-page fixes (title, headings, internal links).

If a page gets zero traffic and targets a topic you care about, it's a candidate for a rewrite or consolidation.

Step 4: Run a Technical Site Audit

Now move to Site Audit. This crawls your site and flags technical and on-page issues.

1. Click Site Audit → New project.
2. Enter your domain and set crawl settings (default is usually fine for a small site).
3. Start the crawl and wait for it to finish.

Once complete, you'll see a Health Score and a list of issues grouped by category.

Which Issues to Fix First

Not all issues are equal. Prioritize in this order:

Ignore low-impact warnings (like minor meta description length) until the big items are handled.

Step 5: Turn Findings Into a To-Do List

You now have raw data. Convert it into a short, actionable list. Example:

1. Fix 3 broken links found in Site Audit.
2. Rewrite title tags on 5 pages with duplicate titles.
3. Improve 4 pages ranking in positions 6–12 by adding missing subtopics and internal links.
4. Remove or update 2 thin pages with no traffic.

Keep the list to 5–10 items max for your first audit. Finishing a short list beats starting a long one.

Common Beginner Mistakes

• Chasing every red flag. Site Audit flags many minor issues. Fix what affects rankings and users first.
• Trusting estimates as exact numbers. Ahrefs data is modeled, not measured from your analytics.
• Auditing a huge site too early. Start small to learn the interface.
• Ignoring search intent. A page can be technically perfect but still fail if it doesn't match what searchers want.
• Forgetting to re-crawl. After fixes, run Site Audit again to confirm improvements.

Where to Go Next

Once your first audit is done:

• Compare with competitors using Site Explorer's Competing Domains and Content Gap reports.
• Track keyword rankings over time with Rank Tracker.
• Explore backlink opportunities in the Backlinks and Link Intersect reports.
• Set up recurring Site Audit crawls so new issues surface automatically.

Your first audit isn't about perfection — it's about building a repeatable habit: enter a target, read the key reports, pick the highest-impact fixes, and act. Do that once a month and your site's health compounds.

Dark Reader is an open-source browser extension that, according to its own documentation, does not send user data anywhere. If your concern is whether installing it exposes your browsing activity to a third party, the available evidence points to no — but the claim is worth checking yourself rather than taking on faith. This article covers what the site states, what "open source" and "no data sent" actually mean in practice, and how to verify both.

What Dark Reader Says About Itself

The official site describes Dark Reader as "an open source eye-care browser extension" that "doesn't send user's data anywhere." It also states it is trusted by 10,000,000 users and has been developed since 2014. Those are the site's own claims, presented on its homepage alongside links to its Help, Blog, Terms of Use, and Privacy Policy pages.

Two of those claims are independently checkable:

• Open source — the code is publicly available, so anyone can read what the extension does rather than relying on the developer's description.
• No data sent — this is a behavioral claim about network traffic, which you can observe directly (see the verification section below).

The user-count and development-history figures are marketing context. They suggest the extension is widely used and long-maintained, which reduces (but does not eliminate) the risk of an abandoned or hastily built tool. They are not security guarantees on their own.

Why "Open Source" Matters Here

An extension that modifies every page you visit sits in a privileged position: it can read page content and, in principle, transmit it. That is exactly why the open-source property carries weight.

With closed-source extensions, you have only the developer's word about what happens to your data. With open source, the code can be audited by anyone — security researchers, other developers, or you. If the extension were secretly sending browsing data somewhere, that behavior would have to appear in the code, and it would be visible.

This does not mean open source is automatically safe. Code can be hard to read, and a malicious change could be introduced in an update. But it shifts the situation from "trust the vendor" to "the behavior is inspectable," which is a meaningfully stronger position.

What "Doesn't Send User Data" Means in Practice

Dark Reader's core function is local: it applies a dark theme to websites by adjusting colors in your browser. The site's instructions describe configuring brightness, contrast, and sepia, and enabling the theme for all websites or only particular domains. None of that requires sending your browsing history to a server — the processing happens in your browser.

So the "no data sent" claim is consistent with how the tool works. A dark-mode extension does not need a remote server to recolor a page, which makes the claim plausible rather than surprising.

That said, "doesn't send user's data anywhere" is the site's phrasing. If you want certainty about a specific version, verify it (next section) or read the Privacy Policy and Terms of Use linked on the site.

How to Verify the Privacy Claim Yourself

You do not have to accept the claim on trust. A few practical checks:

1. Read the Privacy Policy and Terms of Use. Both are linked from the Dark Reader site. These are the documents that state, in binding terms, what the developer commits to regarding your data.
2. Inspect network activity. Open your browser's developer tools (Network tab), use the extension normally for a while, and watch for requests going to unexpected destinations. A tool that sends nothing should generate no suspicious outbound traffic tied to your browsing.
3. Check the source. Because the project is open source, you can review the code or look for third-party security reviews and audits of the extension.
4. Install from official sources only. The site lists official links for Chrome, Firefox, Safari, and Edge. Installing from those store listings avoids counterfeit or repackaged versions, which is a common way "safe" extensions become unsafe.

The last point deserves emphasis: the biggest realistic risk with a popular extension is not the official version but a look-alike copy. Use the official store links the site provides.

A Quick Decision Guide

Bottom Line

Based on the site's own statements, Dark Reader is an open-source extension that does not send user data anywhere, used by a large user base and maintained since 2014. The open-source nature and local-processing design make those claims checkable rather than purely promotional. If privacy is your deciding factor, read the Privacy Policy and Terms of Use, install only from the official store links, and — if you want direct proof — watch the extension's network activity in your browser's developer tools.

Dark Reader is available as an official browser extension for Chrome, Firefox, Safari, and Edge. To install it, open the official store page for your browser, click the install button, and confirm the permission prompt. After installation, the extension applies a dark theme to websites automatically, and you can adjust brightness, contrast, and sepia or limit it to specific domains.

Install Dark Reader on Your Browser

The installation path is the same in principle for every supported browser: go to the official listing, add the extension, then confirm. The table below points to the correct store for each browser.

Use only the official links listed on darkreader.org. Third-party mirrors or repackaged builds are not the official distribution channel.

Step-by-step

1. Open the official Dark Reader page or the store listing for your browser.
2. Click the install/add button for that browser.
3. Approve the permission request when the browser asks. Dark Reader needs access to page content to restyle it.
4. If the page you are viewing does not change immediately, refresh the tab. In some cases a browser restart helps the extension initialize.

Expected result: the site you are viewing switches to a dark theme, and the Dark Reader icon appears in your toolbar.

Configure the Dark Theme

After installation, Dark Reader works on websites by default. The official guidance describes three adjustable settings:

• Brightness — how light or dark the generated theme is.
• Contrast — how strongly text and background separate.
• Sepia — adds a warm tint, which some users prefer for long reading sessions.

You can apply the theme to all websites or enable it only for particular domains. The per-domain option is useful when a site already has its own dark mode or when the generated theme interferes with a specific layout.

What Dark Reader Does and Does Not Do

Dark Reader is an open-source eye-care browser extension. According to the site, it does not send user data anywhere, it has been developed since 2014, and it is trusted by 10,000,000 users. Those claims describe the project's stated privacy stance and scale; they are not a security audit, so treat them as the developer's own description.

It works by generating a dark theme for sites that do not provide one, which is why it can cover Facebook, Amazon, YouTube, Google Search, Wikipedia, Twitter, and many other websites rather than only a fixed list.

Common Installation Issues

• The extension installs but nothing changes. Refresh the page first; if that fails, restart the browser.
• A site looks wrong in dark mode. Disable Dark Reader for that domain instead of turning it off globally.
• Safari does not show the extension. Safari extensions must be enabled in the browser's extension settings after installation, unlike Chrome and Firefox where the add-and-confirm flow usually activates them directly.
• You are unsure which build is official. Start from darkreader.org and follow its links rather than searching a store for similarly named extensions.

Dark Reader is a free, open-source browser extension that applies a dark theme to websites that don't offer one themselves. Instead of relying on each site to build its own night mode, it rewrites colors on the page so text stays readable against a dark background. It's aimed at anyone who wants less bright white on screen — for eye comfort, late-night browsing, or a consistent dark look across the web.

What Dark Reader actually does

Most websites are designed with light backgrounds. Dark Reader generates a dark color scheme for them on the fly, so you get a night-mode appearance even on sites that have never implemented one. According to the project, it works across Facebook, Amazon, YouTube, Google Search, Wikipedia, Twitter, and many other websites.

The extension is described as an eye-care tool. It has been developed since 2014 and is trusted by 10,000,000 users, per the official site.

Key features

• Dark mode on all websites — applies a dark theme broadly rather than only on supported sites.
• Adjustable theme settings — you can configure brightness, contrast, and sepia to tune how the dark theme looks.
• Per-site or global control — you can enable it for all websites or only for particular domains.
• Open source — the code is publicly available.
• No data sent — the project states it doesn't send user data anywhere.

How to get started

1. Install the browser extension. Dark Reader publishes official builds for Chrome, Firefox, Safari, and Edge. Use the official link for your browser rather than a third-party copy.
2. Configure the dark theme. Adjust brightness, contrast, and sepia until the result is comfortable to read.
3. Choose where it applies. Turn it on for all websites, or restrict it to particular domains where you want dark mode.

The expected result: pages that were light now render with a dark background and readable text, and the change follows you across the sites you browse.

Who it's for

Dark Reader suits you if:

• You browse at night or in low light and want to reduce screen brightness.
• You want a consistent dark experience without waiting for each site to add its own dark mode.
• You prefer an open-source tool and care about not having your browsing data sent elsewhere.

It may be less necessary if you only use a handful of sites that already ship a good built-in dark mode, or if you don't want an extension modifying page colors.

Things to keep in mind

• Because Dark Reader recolors pages dynamically, some sites with unusual designs or images may look different from their original styling. The brightness, contrast, and sepia controls exist precisely to correct for this.
• It's a browser extension, so it applies within the browser you install it in — not system-wide across all apps.
• The official site lists separate install links per browser; matching the right build to your browser avoids compatibility problems.

For the current install links and any updates, check the official Dark Reader website for your specific browser.

Dark Reader applies a dark theme to websites in two ways: globally, so every site you open gets darkened, or selectively, so only the domains you choose are affected. You switch between these modes in the extension's settings, and you can flip the current site on or off at any time from the toolbar icon. The official page describes the core flow as: install the extension, configure brightness, contrast and sepia, then "enable for all websites or particular domains."

The two modes you're choosing between

The extension ships with a default behavior, and the official instructions treat "all websites" and "particular domains" as the two options you pick from. Which one is active by default isn't stated on the page, so check your own settings rather than assuming.

Toggling the current site from the toolbar

The fastest control is the extension icon in your browser toolbar:

1. Open the site you want to change.
2. Click the Dark Reader icon.
3. Use the on/off switch at the top of the popup.

Expected result: the page re-renders in dark mode (or returns to its original light styling) immediately, without a reload. This toggle is per-site, so it doesn't change how other domains behave.

Setting global vs. per-domain behavior in settings

1. Open the Dark Reader popup and go to its settings (the page lists "Configure the dark theme: brightness, contrast and sepia" as part of the same setup flow).
2. Find the site-list or automation section, where the extension separates "enabled everywhere" from "enabled on specific sites."
3. Choose the mode that matches your intent:
   • All websites — dark mode becomes the baseline; add exceptions for sites you want left alone.
   • Particular domains — nothing is darkened until you add a domain.
4. Add or remove domains in the list to build your exceptions.

Expected result: after saving, newly loaded pages follow the mode you selected, and any listed exceptions keep their original appearance.

Common snags

• A site looks wrong in dark mode. Add it to your exceptions so it stays light, rather than turning the extension off entirely.
• You toggled a site off but it came back dark. A per-site toggle and a global "all websites" setting can conflict; check which mode is active before re-toggling.
• You want dark mode only on a handful of sites. Pick "particular domains" first, then add each one — starting from "all websites" and subtracting is more work.

Where to install it

The official page points to builds for each major browser: Dark Reader for Chrome, Firefox, Safari, and Edge. The project describes itself as an open source eye-care extension that doesn't send user data anywhere, trusted by 10,000,000 users and developed since 2014.
