Common SEO mistakes in 2025
1.Duplicate content
- Confuses the algorithms used by Google to establish which page should be the focus.
- Repeating the same content — damages trust.
- Fix it: point to the version you want to be ranked with canonical tags.
- Merge related articles into one comprehensive resource /guide.
- And please, do not copy product descriptions from the manufacturer; write them yourself.
- Tag for Title
- The first 100 words
- One subheading
- To wrap up

2. Insufficient Mobile Optimisation
Ignoring mobile optimisation is a big SEO sin, since mobile devices account for more than 60% of all traffic. Because of Google’s mobile-first indexing, rankings are determined by your mobile site rather than your desktop.
Why it’s an issue:
- Higher bounce rates are the result of a poor mobile user experience.
- Rankings are impacted by slower loading times on phones.
- reduces exposure in regional search results.
- The solution is to use responsive design, which adjusts to different screen sizes.
- Use Google’s Mobile-Friendly Test to evaluate your website.
- Navigation will be enhanced by larger buttons, unambiguous menus, and readable fonts.
3. Slow Website Speed
Users anticipate immediate outcomes. More than half of visitors will abandon your page if it takes more than three seconds to load. Under Core Web Vitals, Google also views speed as a key ranking factor.
Why it’s an issue:
- increases the bounce rate and irritates users.
- negatively impacts desktop and mobile rankings.
- reduces conversion rates (less sign-ups and sales).
- Compressing large images is the solution.
- For pages with a lot of media, use lazy loading.
- Minify JavaScript and CSS.
- Select a dependable, quick hosting provider.
For instance, Amazon once discovered that a 100 ms load time delay cost them 1% of sales. Just think of how it would affect smaller companies!
Pro Tip: To find bottlenecks, use programs like Google PageSpeed Insights or GTmetrix.
4. Lengthy or Poorly Written Title Tags
In search results, title tags frequently serve as users’ initial impression of your page. They Why it’s an issue:are cut off if they are too long, and no one will click if they are generic.
Why it’s an issue:
- squanders valuable SEO space. lowers the click-through rate, or CTR.
- confuses search engines regarding the focus of the content.
- The solution is to limit titles to 50–60 characters.
- Put the target keywords close to the start.
- For credibility, finish with your brand name.
For instance, simplify “Best Running Shoes for Marathon Training – Top Picks for Serious Runners in 2025” to “Top Picks: Best Marathon Running Shoes (2025 Guide)”. Pro Tip: To increase CTR, match titles with interesting meta descriptions (about 150 characters).
Lost Connection Possibilities
For Google, internal and external links serve as roadmaps. Your website turns into an
island without them.
Why it’s an issue:
- Not all of your pages may be found by Google crawlers.
- reduces the authority and structure of the site.
- restricts access to other pertinent content by users.
- The solution is to link recently published content to previously successful pages.
- Make use of external links to reliable sources (studies, research).
- Don’t leave pages “orphaned” with no links coming in.
For instance, writing about “SEO trends” Provide links to relevant blogs, such as
“Technical SEO Guide” or “Content Marketing Tips.”
Pro Tip: To improve your internal web, audit your links every three months.
6. Anchor Text Generic
Search engines are informed about the purpose of a linked page by anchor text. It is a
waste of SEO value to use ambiguous text like “click here.”
How to resolve it:
Make use of keyword-rich, evocative anchor text.
Align anchor text with the purpose of the search.
Don’t force it; keep it organic.
For instance, use “learn how to boost site speed with Core Web Vitals” instead of “read
more.”
Pro Tip: Effective anchor text enhances screen reader accessibility in addition to SEO.
7.Ignoring SEO in the local area
If you are a small business and do not care about local SEO, you are leaving sales on the table. Most people who type “near me” into their search want to buy something.
What to do:
- Use location-specific keywords in your meta titles and descriptions.
- Optimize your Google Business Profile.
- Actively solicit local customers to leave reviews for your business.
For example, you could say, “The Best B&B in Atlanta Near the Botanical Gardens” instead of “The Best B&B”.
Industry Tip: Be consistent with how you record your NAP (name, address, phone) across all directories online.
8.Images Without Alt Text
Alt text is important for accessibility as well as SEO. Screen readers use it for people who
are blind or visually impaired, and Google uses it to rank images.
How to resolve it:
- Give succinct, clear descriptions of images.
- Incorporate keywords organically.
- Steer clear of stuffing keywords.
For instance, write “Woman in blue shirt fixing a kitchen tap leak” in place of “woman tap.”
Pro Tip: Many people ignore Google Image Search as a source of traffic, but updated alt
text can help your site rank there.
9.URL Slugs That Are Not Optimised
Both users and search engines find it easier to navigate a URL that is clear and packed with
keywords. Everyone is confused by long, disorganised URLs.
- Slugs should be brief and informative.
- Add the desired keyword.
- Steer clear of random symbols or numbers
For instance:
website.com/p=123
website.com/blog/seo/best-practices for SEO
Pro Tip: Keep the URL under 75 characters and match it to the title of your blog.
10.Outdated Content
Your rankings are most likely being negatively
impacted by the 2019 “Ultimate Guide.” When formerly popular posts
become irrelevant, content decay occurs.
The solution is to perform content audits every six to twelve months.
- Update out-of-date links, screenshots, and statistics.
- Combine several older posts into a single, thorough guide.
- Use “Updated for 2025” to re-promote the updated content.
For instance, adding new 2025 tools to a blog post titled “Best SEO Tools in 2022” will
cause it to rank higher very quickly.
Pro Tip: Freshness is highly valued by Google. Old posts can be brought back to life with
even minor updates
