How To Find SEO Keywords For Your Blog?

In this post, we bring you answers to the most frequently asked questions about SEO keywords and optimization, which follow up on our article "Why is my website not getting any traffic?"

Find SEO keywords based on audience search intent, prioritize long-tail keywords (3–5 words) with lower competition, use Google Keyword Planner and Ahrefs keywords explorer to discover topics and search volume, assign one primary keyword per article + 3–5 secondary ones, place them in H1–H3, URL, meta description, alt text, and measure organic traffic in Google Search Console.

SEO keywords are the exact terms your audience types into search engines, so they should be based on search intent (informational, commercial, navigational). When writing SEO for blogs, choose one primary keyword that matches the article's main topic and several thematically related secondary keywords. Place them naturally in the H1–H3 tags, the first 100 words, the URL, the meta description, and in the alt text for key images. Avoid keyword cannibalization – create a separate article for each topic and link them together with internal linking. This builds a clear structure and strengthens your on-page SEO, leading to growth in organic traffic.

Long-tail keywords are specific queries with lower competition, higher relevance, and typically a higher conversion rate. They help attract more targeted traffic, especially for new domains with lower domain authority. Find them by combining problem + solution (e.g., "seo keywords for blog," "how to find long-tail keywords"), using audience questions, comments, or forum threads. In practice, for a main keyword, write down 10–20 specific long-tail variations and use them in H2/H3 headings, subheadings, and FAQ sections – naturally, without stuffing.

Google Keyword Planner is a free tool for finding new phrases and estimating search volume. Enter a seed keyword (e.g., "SEO keywords") and filter for ideas with lower competition and reasonable volume. Check the trend, seasonality, and question variants, which reveal search intent. Choose between informational queries (e.g., "what is alt text") and transactional queries (e.g., "keyword research tool"). Assign one core topic and 3–5 subtopics to each article – this builds pillar content and topic clusters, which strengthen your on-page SEO and the overall topical relevance of your blog.

Furthermore, Google Keyword Planner also serves as an ad buying tool – if you want to boost traffic to your articles or products, read more in our article about Paid ads on Google and social media. This article summarizes all online advertising options.

In Ahrefs, use the Keywords Explorer to find out Keyword Difficulty (KD) and the SERP (Search engine results page) Overview to understand who currently ranks in the search results. Combine this with the Content Gap tool – you'll discover which keywords your competitors rank for that you don't. For new articles, target long-tail keywords with a lower KD score. For existing articles, look for secondary keyword variations you can add to H2/H3 headings, paragraphs, and the alt text of new visuals. Regularly run a quick site audit (e.g., via an SEO check tool) and review your internal linking to strengthen link equity and prevent keyword cannibalization.

SEO text optimization means combining clear structure with natural language. The H1 is your main question/answer containing the primary keyword. H2/H3 headings develop secondary long-tail keywords. The meta description briefly promises value and uses keywords to encourage a click-through. Alt text describes the image's content, adds context, and is an ideal place for semantically related phrases. Don't stuff – prioritize readability, use synonyms, and employ phrases that reflect search intent. This is how effective SEO for blogs earns natural rankings and better search visibility.

In Google Search Console, monitor organic traffic, impressions, CTR, and average position for each target keyword. Identify queries for which you already rank on positions 8–20, and add specific paragraphs, FAQs, or examples to the article that target these long-tail keywords. Check if your H1–H3 tags, meta description, alt text, and internal links match the search intent. Perform a quick monthly site audit (e.g., an SEO check) and fix minor technical issues that could hinder performance. Continuously compare new topics from Google Keyword Planner and Ahrefs with what's already working and expand your topic clusters.
