I have reviewed hundreds of websites across my career — through technical audits at Salterra, through live sessions in my SEO University cohorts, and through the consulting work I still take on. The mistakes are not random and they are not industry-specific. The same patterns show up in real estate, law, ecommerce, SaaS, healthcare, and every other vertical I have touched. This is my honest, unfiltered account of what breaks most sites and what to do instead.
Targeting Keywords Nobody Actually Searches For
This is the most expensive mistake in terms of wasted effort over time. I see it on nearly every site that has attempted SEO without proper training. Someone spends three months producing content targeting phrases like ‘comprehensive digital marketing solutions for growing SMBs’ — phrases with no meaningful search volume — while ‘digital marketing for small business’ gets searched thousands of times every month.
Keyword research is not optional. It is the foundation every content decision should be built on. The fix is straightforward: use actual keyword research tools with real volume data (Ahrefs, Semrush, or Google Keyword Planner at minimum) and verify search volume before planning any content. Then check the current search results for your target phrase to understand what Google believes the user actually wants — the search intent. If the SERP is full of comprehensive comparison guides and you are writing a 400-word product page, your content is mismatched to the intent regardless of how well it is written.
Thin Content That Does Not Actually Answer the Query
Google’s purpose is to answer user questions more effectively than any other source. A 300-word page about ‘estate planning in Arizona’ that says nothing specific about Arizona statutes, probate courts, or what a reader should actually do next does not answer the query. It is thin content, and thin content does not rank competitively for anything worth ranking for in 2025.
The fix is not adding more words. It is adding more substance. Answer the full query. Define the term. Explain the specific process in your context. Address the trade-offs and common questions. Cover what to do next and how to evaluate options. A well-structured 1,200-word page that completely addresses the searcher’s question will outrank a padded 2,500-word page that circles the topic without landing on anything concrete. Length is a byproduct of comprehensiveness, not a target in itself.
Ignoring Technical SEO Until It Becomes a Crisis
Site speed, crawlability, mobile performance, and indexation health are foundational. I consistently see sites with genuinely strong content underperforming because their technical foundation is broken in ways that are invisible to the content creator but fully visible to Google. Pages that are accidentally noindexed from a misconfigured plugin setting. Duplicate content generated by URL parameters that no one thought to address. Product images that tank mobile Core Web Vitals scores across an entire catalog. Redirect chains left over from a migration two years ago.
The minimum viable technical monitoring: set up Google Search Console properly and check the Coverage and Core Web Vitals reports monthly. That practice alone surfaces the majority of technical problems before they compound into serious ranking losses.
No Coherent Internal Linking Strategy
Internal links pass page authority from stronger pages to weaker ones and signal to Google which pages on your site are most important. Most sites have solid homepage authority and terrible distribution of that authority to deeper content pages. The result: pillar pages and key conversion pages that could rank highly are starved of the internal link equity they need.
Every piece of content you publish should link naturally to two or three related pages already on your site. Your highest-traffic pages should link deliberately to the pages you most need to rank. Your navigation and site architecture should create clear pathways from broad category pages down to specific detail pages. This is not about stuffing links — it is about building a logical information structure that serves both users trying to navigate and crawlers trying to understand your topical hierarchy.
Treating Backlinks as the Primary or Only Ranking Factor
Link building is real and it matters. Authoritative external links remain an important ranking signal. But I see too many site owners prioritizing link acquisition while their on-page content is thin, their technical SEO is broken, and their internal linking structure distributes authority nowhere useful. Links amplify what is already working on a page — they cannot rescue a fundamentally weak page into competitive rankings.
Build links to pages that deserve them: well-written, substantive, genuinely useful content that earns attention because it is actually the best available answer to a real question. Cold outreach to low-quality blogs, link exchanges with unrelated sites, and paid link schemes all carry algorithmic and manual penalty risk that is not proportionate to any realistic benefit. If you would not be comfortable with Google reviewing your link-building approach, reconsider it.
Missing or Incorrect Schema Markup
This is the mistake I am most personally frustrated by because it is consistently overlooked and consistently rewarded when it is finally addressed. Schema markup gives Google structured, machine-readable information about your content — what type it is, who created it, what entity it describes, what questions it answers, what products it reviews. It enables rich results that increase visual prominence in the SERP. It improves click-through rates. And the vast majority of websites either have none, or have it implemented incorrectly in ways that prevent Google from processing it.
Schema markup is my specialty area and I spend dedicated time on it in my SEO training because of how consistently it is both wrong and impactful when corrected. If your site has no schema or has schema with validation errors, that is one of the highest-ROI fixes you can make.
Not Measuring the Right Outcomes
Traffic is a metric. Revenue is a result. I see businesses celebrate aggregate organic traffic growth while their commercial pages rank for nothing that drives actual business decisions. Tracking total organic sessions tells you that traffic went up or down. It does not tell you whether your SEO is growing the business.
Track rankings for the specific queries that drive inquiries, trial signups, consultations, or purchases — not just overall traffic volume. Track conversions from organic by landing page. Track the specific queries your Google Search Console performance data shows are driving actual clicks. Know whether your SEO is moving your business forward or just your dashboard numbers, and you will make much better decisions about where to invest next.
Expecting Results Faster Than the Timeline Allows
SEO is a compounding investment. New content typically takes 3 to 6 months to show meaningful ranking movement in competitive markets, sometimes longer for new domains or in highly contested niches. I see businesses abandon a sound strategy after 60 days because the traffic graph has not moved yet, then pay an agency to restart the same work a year later. Establish realistic timelines upfront, measure the leading indicators (crawl coverage, impressions growth, ranking movement on target queries), and stay consistent with execution. The compounding happens — but only if you let it.
For anyone who wants a structured way to identify which of these mistakes are present on their specific site and build a realistic plan to address them, my SEO training is built around diagnosing real problems on real sites — not walking through abstract concepts and leaving the application as an exercise for later.
