Keyword Research for Affiliate Marketers

Keyword research is your most important task. You need to find keywords that people search for, have buyer intent, and are not too competitive.

 

Semrush keyword research:

Semrush has a massive keyword database (over 25 billion keywords). Enter a seed keyword. Semrush returns thousands of related keywords with search volume, keyword difficulty, and trend data.

 

Best Semrush features for affiliate marketers:

• Keyword Magic Tool – Enter a seed keyword. Get thousands of suggestions grouped by topics. This is excellent for finding long-tail buyer keywords like “best air fryer for small kitchen” or “wireless headphones under $100.”
• Keyword Manager – Save keywords to lists. Track their rankings over time.
• Keyword Gap – Compare your keyword rankings to up to five competitors. Find keywords competitors rank for that you do not. These are opportunities.

 

Ahrefs keyword research:

Ahrefs has a smaller keyword database (over 10 billion keywords) but more accurate search volume data. Ahrefs estimates traffic potential (how many clicks a page actually gets), not just search volume.

 

Best Ahrefs features for affiliate marketers:

• Keywords Explorer – Enter a seed keyword. Get keyword suggestions, search volume, keyword difficulty, and click-through rate data. The click-through rate data is unique and valuable.
• Parent Topic – Ahrefs shows you the main topic driving traffic. If you rank for “best coffee maker,” you also rank for related terms automatically.
• Traffic Potential – Shows you how much traffic the current top-ranking page gets. This is more accurate than search volume alone.

Winner for keyword research: Tie. Semrush has more keywords and better organization (Keyword Magic Tool). Ahrefs has better traffic potential data and click-through rate estimates. Affiliate marketers benefit from both.

 

Buyer Intent Keywords (Most Important for Affiliates)

Buyer intent keywords are searches from people ready to buy. These convert into affiliate commissions.

Examples of buyer intent keywords:

· “best air fryer 2026”

· “Ninja air fryer review”

· “air fryer vs oven”

· “cheap air fryer under $100”

• Semrush for buyer intent: The Keyword Magic Tool is excellent for finding buyer intent keywords. Filter by questions (who, what, when, where, why, how). Filter by prepositions (best, vs, cheap, under, review). Semrush easily surfaces these keywords.
• Ahrefs for buyer intent: Ahrefs also finds buyer intent keywords. The Questions tab in Keywords Explorer shows all question-based searches. The “also rank for” feature shows related commercial keywords.

Winner for buyer intent: Semrush. The filtering options in Keyword Magic Tool make it faster to isolate commercial keywords.

 

Competitor Analysis for Affiliate Marketers

You need to know what your competitors are doing. Which keywords drive their traffic? Where do their backlinks come from?

 

Semrush competitor analysis:

Enter a competitor’s domain. Semrush shows their top organic keywords, top pages, and estimated traffic.

 

Best Semrush competitor features:

• Display Advertising – See competitor’s display ads (useful if you run ads).

 

Ahrefs competitor analysis:

Enter a competitor’s domain. Ahrefs shows their top pages, top keywords, and backlink profile.

 

Best Ahrefs competitor features:

• Site Explorer – See a competitor’s top pages by organic traffic. This shows you exactly which content brings them the most visitors.
• Content Gap – Enter your domain and up to 10 competitors. Ahrefs shows keywords all competitors rank for but you do not. These are your biggest opportunities.
• Backlink Profile – See where competitors get their backlinks. Find link-building opportunities.
• Winner for competitor analysis: Ahrefs. Content Gap is a killer feature for finding missed opportunities. The backlink analysis is unmatched.

 

Backlink Analysis (Link Building)

Backlinks are links from other websites to yours. Google uses them as votes of confidence. More quality backlinks = higher rankings.

 

Ahrefs backlink analysis:

Ahrefs has the largest backlink database. It updates constantly. You can see new and lost backlinks for any site.

Best Ahrefs backlink features:

• Site Explorer – View a site’s entire backlink profile. See the most authoritative links. Filter by dofollow, country, and anchor text.
• Link Intersect – Find websites that link to competitors but not to you. Reach out to these sites for backlinks.
• Broken Link Checker – Find broken links on other sites. Offer your content as a replacement.
• Semrush backlink analysis:

Best Semrush backlink features:

Winner for backlink analysis: Ahrefs. This is Ahrefs’ signature strength. The database is larger, fresher, and more reliable than any competitor.

 

Rank Tracking

You need to know if your SEO efforts are working. Rank tracking shows you where your keywords rank on Google.

Semrush rank tracking:

Semrush tracks keyword positions daily. You can track desktop and mobile separately. The Position Tracking tool shows historical ranking data and estimated traffic from each keyword.

 

Ahrefs rank tracking:

Ahrefs tracks keyword positions (daily on higher plans, weekly on lower plans). Rank Tracker shows your positions, search volume, and traffic potential. Ahrefs also shows SERP features (featured snippets, people also ask, video carousels).

Winner for rank tracking: Semrush. Daily tracking on all plans. More historical data. Better visualization of ranking progress.

 

Site Audits and Technical SEO

Your website needs to be technically sound. Broken links, slow pages, and duplicate content hurt your rankings.

 

Semrush site audit:

Semrush crawls your site up to 100,000 pages (depending on plan). It identifies over 140 issues categorized as errors, warnings, and notices. Each issue includes a description and fix instructions. You can track issues over time.

Ahrefs site audit

Ahrefs crawls your site (up to 100,000 pages on lower plans, more on higher plans). It identifies common technical SEO issues. The interface is simpler and less detailed than Semrush.

Winner for site audits: Semrush. More detailed reports. Better fix instructions. Superior tracking over time.

 

Content Writing Tools

Affiliate marketers write constantly. Review posts, comparison articles, and buying guides.

Semrush content writing tools:

SEO Writing Assistant – Paste your draft. It checks readability, SEO, tone of voice, and originality. It suggests keywords to include. It grades your content against top-ranking pages.

 

Ahrefs content writing tools:

Ahrefs does not have content writing tools. You can use Keywords Explorer to find questions and topics, but there is no writing assistant.

Winner for content writing tools: Semrush. SEO Writing Assistant is a significant advantage for affiliate marketers who write their own content.

Test both before committing. Semrush offers a 7-day trial for $1. Ahrefs offers a $7 for 7-day trial for their Webmaster Tools plan. Spend $8 to test both for a week. Your hands-on experience is the best teacher.
