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.
- Open Site Explorer from the top navigation.
- In the search box, paste your domain (e.g.,
example.com). - 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.
- Press Enter.
You'll land on the Overview report. Don't try to absorb everything — focus on four numbers first.
Reading the Overview Snapshot
| Metric | What it tells you | How to use it |
|---|---|---|
| Ahrefs Rank (AR) | Relative strength of the site's backlink profile vs. others in the database | Useful for comparing against competitors, not as a standalone goal |
| Organic traffic | Estimated monthly visits from search | A rough trend indicator, not exact analytics |
| Organic keywords | Estimated number of keywords the site ranks for | Shows breadth of visibility |
| Backlinks / Referring domains | Total links and unique sites linking to you | Referring domains matter more than raw backlink count |
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:
- Your top performers — understand what topics and formats work. Can you create more content like this?
- 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.
- Click Site Audit → New project.
- Enter your domain and set crawl settings (default is usually fine for a small site).
- 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:
| Priority | Issue type | Why it matters |
|---|---|---|
| 1 | Broken links (404s) | Bad for users and crawl efficiency |
| 2 | Pages blocked from indexing | They can't rank at all |
| 3 | Missing or duplicate title tags | Directly affects click-through and relevance |
| 4 | Slow-loading pages | Affects experience and rankings |
| 5 | Thin content | Low value to users and search engines |
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:
- Fix 3 broken links found in Site Audit.
- Rewrite title tags on 5 pages with duplicate titles.
- Improve 4 pages ranking in positions 6–12 by adding missing subtopics and internal links.
- 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.
What Is the MESON Chess Problem Database and How Do You Use It?
MESON is a free, online database of chess problems and endgame studies hosted on the BDS Website (bstephen.me.uk), run by Brian Stephenson. According to the site, it has been free and online since 2006 and currently contains more than 256,000 items. It is the right resource if you want to look up composed problems, search for a specific composer's work, or study endgame studies — rather than browse casual tactics puzzles.
What MESON actually contains
MESON is a chess problem database, not a game database. That distinction matters:
- Chess problems are composed positions with a stipulated task (for example, "mate in 2" or "mate in 3"), usually with a unique solution the composer designed.
- Endgame studies are composed endgame positions where the task is normally to win or draw, again with a constructed, often surprising solution.
The site describes MESON as containing "more than 256,000 items," covering this kind of composed material. It does not claim to be a record of played games, so don't expect opening statistics or tournament results here.
How to access it
Access is through the BDS Website's navigation menu:
- Go to the BDS Website (bstephen.me.uk).
- Select the MESON menu item.
- You land in the database itself, where you can search and browse.
The site states MESON has been free and online since 2006. No pricing, account, or login requirement is mentioned in the available site information, so treat access as open browsing unless the site itself tells you otherwise when you arrive.
How to search for problems and studies
The site's own description does not spell out the search fields, so the practical approach is to work from what a problem database of this kind is built to answer. Typical ways to use it:
- By composer — if you already know whose problems you want (for example, work by a specific problemist), a composer search is the fastest route.
- By problem type or stipulation — mate-in-2, mate-in-3, helpmate, selfmate, study, and similar categories let you narrow to the genre you care about.
- By position — entering the pieces or a diagram position lets you find whether a given setting already exists, which is useful if you are checking a composition or studying a theme.
Because the exact field names and menu labels are not documented in the source material, verify them on the MESON search page itself rather than assuming a fixed layout. The database is implemented with MySQL and Perl (with CGI::Simple, HTML::Template and XML::LibXML) and a jQuery/Bootstrap/DataTables front end, which is consistent with a searchable, table-driven interface.
What else is on the BDS Website
MESON is one part of a larger site, and the surrounding sections are useful if you want context or related material:
| Section | What it offers |
|---|---|
| Chess Problems | Brian Stephenson's own compositions, published since 1977 and being added gradually |
| Endgame Studies | His articles on endgame studies, written in Chess since 2006 and, with Roland Ott, in Schweizerische Schachzeitung since 2014 |
| MESON | The main problem database (256,000+ items) |
| BDS Ladder | A former problem-solving competition, now closed, but the problems used are still available to try |
| IT | Notes on the software and tools used to build the site |
| Blog, Audio Drama, Photos | Non-chess personal content |
If your interest is specifically endgame studies, the Endgame Studies menu and MESON together cover both the articles and the underlying positions.
Practical tips
- Start narrow. With 256,000+ items, searching by composer or stipulation first will get you to relevant material faster than browsing.
- Use the Ladder problems for practice. The BDS Ladder is closed as a competition, but the site keeps its problems available if you want solving practice.
- Check the composer's own page for context. Stephenson has composed and published problems since 1977, and his Chess Problems section is a small, curated complement to the much larger MESON collection.
- Contact route. The site points to the BCPS Website contact page, where Stephenson is listed as magazine curator, if you need to reach him.
MESON is best understood as a specialist reference for composed chess problems and studies: free, long-running, and large enough that targeted searching beats casual browsing.
What Does Design Mean in Stainless Steel Fabrication?
In stainless steel fabrication, design means engineering the part so it can actually be made: setting dimensions, material grade, joint and weld details, finish and tolerances, then checking that the workshop can cut, form, weld and finish it as drawn. It is not graphic design or product styling. This stage matters whenever you need a bespoke stainless item — a frame, tank, duct, pipework run or enclosure — and it usually starts from your sketch, sample or drawing rather than a finished CAD model.
What the design stage covers
Design work in a fabrication shop turns an idea into instructions the workshop can follow. That normally includes:
- Geometry and dimensions — overall sizes, bend radii, hole positions, and how parts fit together.
- Material grade — which stainless grade suits the environment (for example a grade chosen for corrosion resistance or for weldability). The fabricator should confirm the grade rather than assume it.
- Joint and weld details — where seams run, whether welds are visible or dressed, and how access is provided for the welder.
- Finish — the surface treatment required, such as a brushed, polished or other finish, and which faces are cosmetic.
- Tolerances — how accurate the finished part must be, since tighter tolerances generally mean more work.
How design decisions affect manufacture and cost
Most cost and lead-time differences between two apparently similar parts come from design choices, not from the amount of steel:
| Design choice | Effect on fabrication |
|---|---|
| Complex geometry with many bends | More forming steps, more chances of distortion |
| Welds in hard-to-reach positions | Slower welding, higher risk of defects |
| Visible, dressed welds | Extra finishing time |
| Tight tolerances | More checking and rework |
| Cosmetic finish on all faces | More handling and protection during work |
A design that is easy to weld and finish is usually cheaper and faster than one that only looks simple on paper.
Typical design-to-manufacture workflow
- Brief or sketch — you provide a drawing, sketch, photo or sample, plus what the part must do.
- Design review — the fabricator checks feasibility, suggests changes, and confirms grade, finish and tolerances.
- Agreed drawing — a dimensioned drawing or model is signed off before cutting starts.
- Fabrication — cutting, forming, welding and finishing to the agreed drawing.
- Inspection — the finished part is checked against the drawing and finish specification.
The design review step is where most problems are caught cheaply, before any material is cut.
Common design mistakes that cause delays
- Missing dimensions, or dimensions that do not add up.
- No material grade specified, or a grade that is hard to weld or form.
- Finish left undefined, so the workshop guesses.
- No tolerance stated, leading to disagreement at inspection.
- No allowance for weld distortion on large or thin panels.
- Cosmetic faces not marked, so they get scratched during handling.
Questions to ask a fabricator at the design stage
- Which grade do you recommend for this environment, and why?
- Can this be made as drawn, or would a small change reduce cost or lead time?
- Which faces are cosmetic, and how will you protect them?
- What tolerance can you hold, and how will it be checked?
- Will welds be visible, dressed or hidden?
- What do you need from me before you can quote and start?
Getting clear answers to these before fabrication begins is the practical way to avoid rework and unexpected cost.
What Is a Plane and How Do You Identify One on a Flight Tracker?
A plane (aircraft) is a powered flying vehicle with fixed wings and engines, and on a live flight tracker it appears as a moving icon tied to a unique identity — usually a registration, an ICAO 24-bit hex code, and a callsign. You can identify a specific plane by searching any of those identifiers on a tracker such as Flightradar24, then reading the aircraft type, altitude, speed, and route from its detail panel. This works for most commercial and many private flights, but a plane may be missing or show incomplete data if it is outside receiver coverage, not transmitting ADS-B, or operating under a blocked or filtered identity.
What counts as a "plane" in flight tracking
In everyday use, "plane" means any fixed-wing aircraft: airliners, cargo freighters, business jets, and light general-aviation aircraft. Flight trackers also display helicopters and some military aircraft, so the icon you see is not always a fixed-wing plane.
The main categories you will encounter on a tracker:
| Category | Typical examples | What you'll notice on a tracker |
|---|---|---|
| Commercial airliners | Narrow-body and wide-body jets | Full route, scheduled callsign, high and steady cruise altitude |
| Cargo aircraft | Freighters | Similar to airliners, often night operations |
| Business jets | Private and charter jets | Variable routes, less predictable schedules |
| General aviation | Light single- and twin-engine planes | Lower altitude, shorter flights, often partial data |
| Helicopters | Rotorcraft | Slow speed, low altitude, hovering or circling |
How a plane is identified
A single aircraft carries several identifiers, and trackers let you search by any of them.
- Registration — the tail number painted on the aircraft, such as a national prefix plus letters or digits. This identifies the physical airframe.
- ICAO 24-bit hex code — a unique six-character hexadecimal address assigned to the aircraft's transponder. This is the most reliable identifier because it does not change with the flight.
- Callsign — the flight or operational identifier used in radio communication, such as an airline code plus a number. The same callsign can be reused on different days and sometimes by different aircraft.
- Flight number — the commercial number passengers see, which usually maps to a callsign but is not identical to it.
If you know the registration or hex code, you are identifying one specific plane. If you only know a flight number, you are identifying a scheduled flight, and the aircraft assigned to it can change.
How to look up a specific plane on a live flight tracker
Using Flightradar24 as the example, the general workflow is:
- Open the live map. You see aircraft as icons moving in real time, colored and shaped by type and altitude.
- Search by identifier. Enter a registration, callsign, or flight number in the search field. The map centers on the matching aircraft if it is currently being tracked.
- Select the aircraft. Clicking an icon opens a detail panel.
- Read the details. The panel typically shows aircraft type, registration, altitude, ground speed, heading, vertical rate, origin and destination, and the route history.
- Follow it. Selecting and following an aircraft keeps the map centered on it as it moves, so you can watch a flight in real time.
The expected result is a live position plus a set of aircraft and flight details. If the search returns nothing, the plane is likely not transmitting or not currently within coverage.
What details a tracker shows for a plane
Once you select an aircraft, the detail view usually includes:
- Aircraft type — manufacturer and model, sometimes with the specific variant.
- Registration and hex code — the airframe identity.
- Altitude — current height, often in feet.
- Speed — ground speed, often in knots.
- Heading and vertical rate — direction of travel and whether it is climbing or descending.
- Route — origin and destination airports, plus the flight number.
- Position history — the path already flown, shown as a trail on the map.
These fields are what let you confirm you are looking at the right plane rather than just a similar one nearby.
Why a plane may not appear or shows incomplete data
- Outside receiver coverage — tracking depends on a network of ground receivers and satellite data. Over oceans, remote regions, or at low altitude, coverage can be sparse.
- Not transmitting ADS-B — some aircraft use older transponder modes or have equipment that a given tracker cannot decode.
- Blocked or filtered identity — some operators request that their aircraft not be displayed, so the plane is intentionally hidden.
- Incomplete route data — the aircraft may be transmitting position but not a matched flight plan, so origin and destination can be blank.
- Delayed or estimated positions — in low-coverage areas, the shown position may be an estimate rather than a fresh fix.
If a plane is missing, try searching by registration or hex code instead of flight number, and check whether it is currently airborne. A plane that has landed or not yet departed will not appear as a live target.
Practical takeaway
To identify a plane on a tracker, start with the registration or ICAO hex code for a specific airframe, or a callsign or flight number for a specific flight. Then read the aircraft type, altitude, speed, and route to confirm it. Expect gaps when a plane is out of coverage, not transmitting ADS-B, or deliberately filtered — in those cases the tracker simply has no live data to show.
Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.
Domain and Registration
Registered in 2013, this domain has about 13 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The registrar is GoDaddy.com, LLC, a widely used domain service provider. The domain uses the common .com extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by Cloudflare, indicating managed DNS hosting. MX records point to the Fastmail email service. DNSSEC is enabled, allowing validating resolvers to authenticate signed DNS data. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown.
TLS and Certificates
The public key uses EC with 256 bits. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued within the Google Trust Services cloud or CDN ecosystem. The certificate's total validity is about 90 days, consistent with a short renewal cycle.
HTTP and Browser Security
The response lacks these common security headers: CSP, Permissions-Policy. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The cf-ray response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers. The Server header identifies cloudflare without an exact version.
Technology Stack Analysis
The public page identifies Cloudflare without precise versions, leaving fewer clues for version-specific scanning.
