What Is SEO? A Practical Guide to Search Optimization
Every B2B marketing team wants to get competitor website traffic estimates that hold up under scrutiny — and most end up paying for tools they never open twice. This piece covers the analysis method that actually works, the tools worth a subscription, and a monthly workflow SMEs, scale-ups and agencies can repeat without hiring an analyst.

You cannot see a competitor's real analytics. You can track modelled estimates that are directionally useful, and the shape of the trend is what to monitor — not the absolute number.
Two tools beat one. Cross-reference Similarweb and either Semrush or Ahrefs, and treat any figure that agrees within 30 percent as a fair estimate of your competitors' traffic.
Keyword rankings, referring domains and top pages tell you far more about what your competitors are doing than the headline traffic number does.
Monitor monthly, not weekly. A one-hour cadence with two tools and a shared spreadsheet is what most competitor monitoring programmes actually need.
The point of the analysis is to decide what your team should do next — not to build a dashboard for its own sake.
Why competitor website traffic analysis matters
Every team benchmarks against something. The question is whether the benchmark is a real competitor or a generic industry average — and a competitor benchmark is worth several times more. A number from your own niche tells your team what "good" looks like on a website of similar age and commercial model. A global average tells you nothing you can act on.
What a rigorous competitor analysis really answers is not "how much traffic does the competitor get?" — it is "which of their plays are working, and which of those can our team copy or leapfrog?" That is a more actionable question, and it is the reason a competitor monitoring programme changes decisions rather than decorating reports.
For SMEs, scale-ups, agencies and SaaS marketing teams the same three use cases keep coming up. First, sizing the market — competitors with visible traffic prove the demand exists. Second, prioritising channels — if two competitors both grew through content and one through paid, your next quarter is probably about content. Third, defending share — a competitor pulling ahead on branded search is a signal you need to track and respond to, not a spreadsheet.
None of that needs a full-time analyst. What it needs is the right tools, the right handful of metrics to track, and a workflow the marketing owner can keep up with.
What your competitors leak about their website traffic
A competitor cannot hide most of what matters. Their website is public, their content is public, their inbound links are public, and every third-party tool that models website traffic reads the same signals. Knowing what to track — and what to skip — helps your team spend an hour on the data that changes decisions.
What competitors leak
What tool sees it
How much decision it supports
Estimated monthly website traffic
Similarweb, Semrush, Ahrefs
Directional — trend is more reliable than the number
Ranking keywords and top pages
Ahrefs, Semrush, Serpstat
High — tells you what content is actually working
Referring domains and link velocity
Ahrefs, Majestic
High — shows the authority strategy your competitors use
Paid keywords and ad copy
Semrush, SpyFu
Useful for scale-ups; SMEs can usually skip it
Social share of voice
BuzzSumo, Sparktoro
Useful for content-heavy competitors
Technology stack
BuiltWith, Wappalyzer
Rarely changes a marketing decision — skip most months
Notice how much of what your competitors leak lives in tools your team can open for free. The paid tiers add depth on top pages, keyword history and referring domains — the layers that support real decisions. The rest is noise most of the time.
Tool choice
Which tools to use for competitor traffic analysis
Four tools cover 95 percent of what a marketing team needs to track competitors. Pick two — a traffic tool and a search tool — and skip the rest until a specific question demands them.
Similarweb — traffic and channel mix
The default tool for a headline website traffic estimate, channel split and country breakdown for any competitor. Trend is reliable, absolute numbers are not — treat the graph as the truth and the label as a rough guide.
Ahrefs — keywords and links
The strongest tool for the keyword universe your competitor ranks for and the referring domains they have earned. Use it to see what content and authority your competitors are actually building.
Semrush — the all-rounder
A single tool that covers traffic estimates, paid search keywords, position tracking and ad copy. Weaker than Ahrefs on links and than Similarweb on channel mix, but a fair choice if your marketing team can only fund one paid tool.
Google Search Console + a spreadsheet
Free, and the only tool that reports your own website's true position. Combine what you rank for with a competitor's public ranking data from Ahrefs, and you have a keyword gap analysis no paid tool sells better.
How to get competitor website traffic estimates that hold up
The single biggest mistake teams make on a competitor traffic analysis is trusting a single tool. Every tool models website traffic from a different panel, so their numbers disagree — sometimes by a factor of two. The fix is straightforward: use two tools, note where they agree and where they diverge, and treat the agreement zone as the fair estimate.
Here is the practical method our analysts use to get competitor website traffic figures that survive a management review. It takes about twenty minutes per competitor and delivers a number you can defend without an asterisk.
Pull the monthly traffic estimate from Similarweb. Note the number and the trend line for the last twelve months. If the tool marks the estimate as "low confidence" — a small competitor site — the absolute figure is not worth quoting.
Pull the equivalent from Ahrefs or Semrush. Focus on organic traffic; each tool models it separately, so a second number is a second data point.
Compare the two. If they land within 30 percent of each other, take the midpoint. If they diverge more, quote both and let the reader see the range.
Cross-check against a proxy signal. Referring domains, ranking keyword count and branded search volume all move alongside real traffic — a competitor's tool numbers should not disagree with those proxies.
Log the number in a shared spreadsheet. One row per competitor, one column per month. The value of the analysis compounds only if the history exists.
Do this once and the numbers look noisy. Do it every month for two quarters and the shape of each competitor's website traffic becomes obvious — who is genuinely growing, who is stalling, and who is buying visibility rather than earning it. That shape is what a marketing team can actually act on.
How much traffic does my competitor get, really?
"How much traffic does my competitor get?" is the first question a marketing owner asks, and the honest answer is that nobody outside the competitor's own analytics knows the exact number. The tools estimate it, and the estimates disagree — often by a wide margin. What you can trust is the order of magnitude and the direction of travel.
To make that concrete, here are the bands our analysts use when a client asks how much traffic a competitor's website is really getting. Treat them as directional, and always compare a competitor against websites of similar age and niche rather than against a global average.
Modelled monthly traffic
What it usually means
How much confidence to put in the number
Under 5,000 sessions
New or small B2B website, likely under the tool's detection floor
Low — the estimate can be off by 3x either way
5,000 to 50,000
Established SME website with a working content or paid channel
Medium — trend reliable, absolute number roughly indicative
50,000 to 500,000
Scale-up website with a real content library and link base
Good — tools converge, trend is highly reliable
500,000+
Category leader; tools disagree on absolutes but agree on shape
Good on trend, poor on the label
What matters commercially is rarely the headline number. It is how much of that competitor traffic your website could plausibly capture, which comes back to keyword overlap, referring domain overlap, and the shape of each competitor's channel mix. A competitor with 200,000 monthly sessions almost entirely from branded search is a much weaker threat than one with 40,000 sessions from your exact commercial keywords.
Understanding SEO
SEO stands for Search Engine Optimization. It improves a website's visibility in search engine results pages, or SERPs.
So, what is search engine optimization in digital marketing? It is the work of making pages useful, clear, fast, and trusted.
The British spelling leads to another common query: what is search engine optimisation seo? The answer stays the same. SEO helps search tools match useful pages with people who need them.
Some readers ask, what is search engine optimization seo? They want a plain definition. SEO is a long-term way to earn visits from unpaid search results.
Search engine optimization seo is a means by which a business can reach people during active research. It joins content, site health, and trust signals.
Google covers these core ideas in its SEO Starter Guide. The guide stresses helpful content and clear site structure.
Why SEO Matters for a Website
Search often starts a buying journey. A person may spot a problem, compare choices, then pick a provider.
SEO can place your site at each stage. It can build trust before a visitor speaks with your team. It can also lower the cost of each visit over time.
Is paid search the same as SEO? No. Paid search buys ad space. SEO earns unpaid rankings through useful pages and strong site signals.
Good SEO can raise traffic quantity and traffic quality. More visits help only when they come from the right audience.
Results take time. A new page may need weeks or months to gain steady rankings. Results depend on rivals, site history, content, and site health.
Reach people who already seek your topic
Build trust through useful answers
Gain visits without paying for every click
Learn what customers need from search data
The Main Components of SEO
SEO has three broad parts. Technical SEO helps search tools reach and read your site.
On-page SEO improves the page itself. Off-page SEO builds trust beyond your site.
Keyword research links your pages with real searches. Search volume means the number of searches for a term over a set time.
What is search volume in SEO? It is a useful demand clue. It does not show search intent, business value, or likely sales.
What is search intent in SEO? It is the goal behind a search. A person may want to learn, compare, find a site, or take action.
Semantic search looks at meaning and context. What is semantic search in SEO? It means search tools assess the topic behind words, not just exact matches.
Voice search affects SEO by adding more spoken, question-based searches. Voice search is changing SEO in small ways. Clear answers and natural phrasing now matter more.
Technical health and crawl access
Useful page content and clear headings
Links and trust from other sites
Strong use on phones
Tracking for visits, leads, and sales
Technical SEO Explained
Technical SEO helps search tools crawl and index your site. Crawling means finding pages. Indexing means storing pages for search.
Start with speed and mobile use. Slow pages can frustrate visitors and raise exit rates.
Site structure matters too. Keep key pages a few clicks from the home page. Link related pages with clear paths.
An XML sitemap lists key URLs for search tools. Robots.txt gives crawl guidance. Neither file can fix weak content.
Structured data adds machine-readable details to a page. It can describe products, reviews, events, or articles.
Search engine submission in SEO means sending a site or sitemap to a search tool. Modern tools often find pages through links and sitemaps. Submission does not guarantee a ranking.
Check site health in Google Search Console. It shows indexing issues, queries, clicks, and impressions.
Fix problems in this order:
Make important pages crawlable
Remove broken links and bad redirects
Improve mobile layout and page speed
Submit and check your sitemap
Test structured data on key pages
Technical site health review
On-Page SEO and Off-Page SEO
On-page SEO covers changes within your website. It includes topics, titles, headings, images, links, and copy.
How to do onpage optimization in SEO starts with one clear topic per page. Place the main phrase in the title and opening section.
Use related terms only when they help the reader. Avoid forced repeats. Helpful copy should sound natural.
What is image optimization in SEO? It means making images fast, clear, and useful. Use suitable file sizes, descriptive names, and short alt text.
Alt text helps people who cannot see an image. It should describe the image's role on the page.
Off-page SEO covers signals outside your site. Backlinks are links from other sites. A relevant link from a trusted site can support your site's authority.
Search engine link building means earning links from useful, related sources. Search engine optimisation link building uses the same basic method.
Search engine optimization link building is not a race for the most links. Strong links tend to come from real partnerships, useful research, and newsworthy work.
Social media engagement can widen reach. It may also help more people discover and share your content.
Write pages that solve a clear problem
Link to related pages within your site
Earn mentions from trusted, relevant sites
Keep business details and reviews accurate

How to Build an SEO Strategy
How to do search engine optimization yourself starts with a focused plan. Pick one audience, one goal, and a small group of topics.
First, review your site. Find missing pages, weak titles, broken links, slow templates, and poor mobile use.
Next, study the searches your audience makes. Group them by need, not just by wording.
Then, map each group to one page. This prevents several pages from competing for the same search.
Create the best useful answer you can. Add examples, steps, proof, and clear next actions.
Build links between related pages. Then seek mentions from trusted sites in your field.
Use this simple work list:
Set a clear business goal
Check technical site health
Study topics, intent, and search volume
Improve titles, headings, copy, and images
Publish useful pages on a steady plan
Earn relevant links and mentions
Review results and update weak pages
Small sites can make steady gains with this method. Focus on useful work rather than quick tricks.
Measuring SEO Success
SEO reports should link search activity with business results. Rankings matter, but they are not the final goal.
Track impressions, clicks, visits, engagement, leads, and sales. Compare these figures by page, topic, device, and landing path.
Analytics can show traffic sources and user behavior. It can also show where visitors leave before taking action.
Use a clear review cycle. Check technical errors each month. Review key pages each quarter. Update pages when facts, needs, or rivals change.
Measure
What it shows
Impressions
How often pages appear in search
Clicks
How often searchers visit
Engagement
How visitors use the page
Conversions
How visits support business goals
Look for patterns, not single-day changes. Search demand can shift with seasons, news, and product cycles.
SEO works best as a repeated process. Learn what helps users, improve the page, and measure the next result.
Monthly workflow
One hour a month, four steps
A repeatable competitor website traffic analysis workflow the marketing owner can run alone.
01
Pull and track the numbers
Open your two tools, pull the five metrics above for each competitor, and drop them into the shared spreadsheet you use to track everything. Fifteen minutes if your list has five competitors.
02
Spot the moves
Look for any metric you track that changed more than 20 percent month over month. Those are the moves worth understanding — everything else is noise your team can ignore.
03
Investigate the top move
Open the competitor's website, find the new content, links or campaigns that explain the move. Screenshot the evidence and paste it into the same spreadsheet.
04
Write five lines
Summarise for the team: what changed, why it changed, what your marketing should do about it. A five-line summary read in a stand-up beats a 20-tab dashboard nobody opens.
One hour a month, two tools and a spreadsheet — enough to track what competitors are doing and monitor how their moves compare to yours.
What goes wrong
Six ways teams waste the analysis
Every mistake here is common on a competitor analysis programme — and every one turns useful data into a report nobody reads.
Trusting one tool
A single tool's number is a modelled guess. Two tools that agree within 30 percent are worth quoting; one tool alone is not.
Tracking too many competitors
Five is the ceiling most marketing teams can actually track monthly. Ten becomes a chore, twenty becomes abandoned, and the analysis dies inside a quarter.
Chasing the absolute number
Debating whether a competitor gets 42,000 or 58,000 monthly sessions is time your marketing team will never get back. Trend and channel mix change decisions; the label does not.
Skipping the spreadsheet
Without a monthly log, no trend exists. A screenshot in Slack is not an analysis — it is a snapshot that will be forgotten in a week.
No follow-through action
If nothing in the marketing plan changes because of the analysis, the analysis is decoration. Every monthly review must end with an owner and a next step.
Comparing to giants
Benchmarking a 12-month-old SME website against the category leader tells your team nothing useful. Compare like with like or the numbers demoralise everyone.
If your competitors are pulling ahead
Move the numbers your competitors watch
Once your competitor analysis shows a rival's Similarweb curve climbing on their traffic buys, our Similarweb traffic service and managed web traffic move your own website into the same reporting bracket — with a written plan, live dashboard and SLA.
What SME marketing owners and agencies actually ask when they start monitoring competitor websites.
How much traffic does my competitor get, and can I see the real number?
You cannot see the exact number — only the competitor themselves can. What you can see is a modelled estimate from Similarweb, Semrush or Ahrefs, plus the search visibility those tools track. Use two tools rather than one, and treat the trend as more reliable than the absolute figure.
How do I get competitor website traffic estimates for free?
The free tiers of Similarweb, Ubersuggest and Semrush all show a monthly traffic estimate for any public domain. It is enough to spot which competitor is growing and which is stalling — buying a paid tool only becomes worthwhile once your marketing team wants to track keyword-level movement or referring domains in detail.
Which competitor traffic tool is the most accurate?
None of them are accurate in absolute terms — each tool models traffic from different panel data, and figures routinely differ by 30 to 60 percent across tools for the same competitor. Similarweb tends to over-estimate large B2C sites, Ahrefs under-estimates them, and Semrush lands somewhere between. Trust the trend line, not the label.
How often should a marketing team monitor competitor websites?
Monthly is enough for most SMEs. A weekly cadence adds noise without signal, and a quarterly cadence misses the moves worth reacting to. One hour a month with two tools, one shared spreadsheet and a five-line summary covers what most marketing teams actually need to track.
How many competitors should I track?
Five is the practical maximum for a one-person marketing function. Split them into three direct competitors and two aspirational competitors — enough to see the shape of the market without turning the analysis into a weekly chore.
What if a competitor's website traffic estimate looks suspiciously high?
Cross-check with a second tool and monitor their referring domains. If competitors' traffic is climbing while their ranking keyword count and referring domains are flat, they may be buying traffic rather than earning it. Useful information — it tells you how much of their visible growth is defensible.
Can I get competitor website traffic data without paying for a tool?
Yes, to a limited depth. Similarweb and Ubersuggest free tiers cover the headline monthly traffic estimate. Google Trends covers branded search interest over time. Together they answer the "how much" question well enough for most SMEs — the paid tools earn their subscription when your team needs keyword-level detail every month.
How does competitor analysis feed into our own marketing plan?
Every monthly analysis should end with one decision. If a competitor gained on branded search, your marketing plan needs a brand response. If they added referring domains, your team owes itself a link push. If nothing changed, do nothing — a quiet month for your competitors is a quiet month for your plan too.
