Which SEO tactics and common mistakes should you avoid, and how should you adjust your strategy?

SEO mistakes to avoid go beyond ranking manipulation. They also include choosing keywords at random, publishing content that does not match search intent, using conflicting canonical URL settings, and treating optimization as a one-time task. The way forward is to address users’ actual needs, check that technical settings are consistent, and keep refining your approach based on performance. Not cheating is no guarantee of rankings or protection from penalties, and a drop in clicks alone does not mean the entire strategy has failed.

Avoid manipulative tactics, but do not treat every redirect as cheating

Semrush’s 2023 article on real estate SEO lists keyword stuffing, buying backlinks, publishing duplicate articles with only place names changed, deceptive redirects, and hiding text to pack in keywords as practices to avoid, warning that they may carry a risk of penalties. This reflects the article’s guidance at the time, not the full text of current official policies, and does not mean every instance will necessarily receive the same treatment.

The key is how a technique is used. For example, hiding large numbers of target keywords as white text on a white background is the kind of manipulation described in the source material. That does not mean all hidden interface elements or legitimate URL redirects should be considered violations.

Confirm search intent before choosing a content format

Semrush’s article on keyword strategy says a strategy should include target keywords, corresponding content, and priorities for allocating resources, rather than simply writing whatever comes to mind. When reviewing existing content, check the following:

• Are users looking for information, comparing products, or preparing to buy?
• Do the answers on the page serve that purpose?
• Do the keywords you invest in support business goals, and can you measure the results?

The article uses “women’s dresses with pockets” as an example: if the intent is to find products, a tutorial on sewing pockets may not meet searchers’ needs, even if it is well written. In that case, adjust the page to meet the demand rather than increasing the number of keyword mentions.

Canonical URLs are not a shortcut for combining the rankings of different pages

A Semrush article on canonical URLs, marked as published in 2020, recommends using canonical tags for identical or very similar content, not to consolidate pages that are merely related. For example, for two different headphone models, the article recommends that each page use a self-referencing canonical tag to preserve its opportunity to rank independently.

• Check whether the CMS and plugins generate duplicate tags that specify conflicting preferred URLs.
• If the specified URL immediately redirects, the article recommends pointing directly to the final destination.

These are technical checks recommended by that article. Conflicting settings may cause search engines not to use the specified URL; this should not be described outright as a penalty against the website.

Review your strategy regularly rather than focusing only on clicks

Neil Patel’s 2026 article notes that algorithms and competitors change, so SEO strategies need regular review. Seer’s 2025 analysis offers conditional recommendations: if a team is gaining impressions but receiving fewer clicks, it should reassess its KPIs; if paid click-through rates are declining broadly, it should then consider testing other channels and adjusting budgets and creative assets. This is not a call to abandon click metrics, but a warning against blaming every decline on content or the team responsible for execution before understanding what has changed.
