--- name: SEM description: Search engine marketing strategy, keyword bidding, quality score optimization, and paid search campaign management metadata: category: marketing skills: ["sem", "ppc", "google-ads", "paid-search", "adwords"] --- ## Keyword Strategy - Exact match isn't exact anymore — Google includes "close variants" (plurals, misspellings, implied intent). Review search terms report weekly - Broad match needs smart bidding — without automated bidding, broad match burns budget on irrelevant queries - Long-tail keywords have lower CPC but need volume — 100 low-volume keywords won't spend, consolidate into phrase/broad with negatives - Competitor brand bidding is legal but expensive — CPCs are 2-5x higher and Quality Scores stay low. Budget accordingly - Single Keyword Ad Groups (SKAGs) are outdated — Google's algorithm works better with theme-based ad groups of 5-15 related keywords ## Quality Score Impact - Quality Score affects CPC exponentially — QS 10 pays ~50% less than QS 5 for same position - Three components: expected CTR, ad relevance, landing page experience. Check diagnostics to know which to fix - Historical CTR matters most — new keywords inherit account-level history. Poor performers drag down new campaigns - Landing page speed is a ranking factor — compress images, remove unnecessary scripts before scaling spend - Ad relevance requires keyword in headline — dynamic keyword insertion ({KeyWord:Default}) is cheap but effective ## Bidding Mistakes - Manual CPC leaves money on table at scale — switch to automated bidding after 30+ conversions/month - Target CPA too aggressive kills volume — start 20% above actual CPA, tighten gradually - Maximize Conversions without cap spends entire budget regardless of efficiency — always set a target CPA or ROAS - Enhanced CPC (ECPC) is neither manual nor smart — commit to one strategy, ECPC is the worst of both - Bid adjustments stack multiplicatively — +50% device × +30% location = +95%, not +80% ## Campaign Structure - Search and Display in same campaign is always wrong — different intents, different metrics, split them - Brand campaigns should be separate — protect branded terms, track true branded vs non-branded performance - Geographic targeting at campaign level, not ad group — easier budget control by region - Audience layering (observation mode) first — collect data before switching to targeting mode that restricts reach - Shared budgets hide which campaigns would spend more — use individual budgets to understand true demand ## Ad Copy Rules - Include primary keyword in Headline 1 — ad relevance and CTR both improve - Responsive Search Ads need 8-10 headline variations — algorithm can't optimize with only 3-4 options - Pin critical messaging to position 1 — brand name, key offer, or compliance text that must always show - Call extensions increase CTR 5-10% — add phone number even if calls aren't primary goal - Test exactly one element at a time — headline vs headline, not headline + description + CTA simultaneously ## Search Terms Hygiene - Review search terms weekly, not monthly — irrelevant spend compounds fast - Add negatives at campaign level for broad exclusions, ad group level for specific refinement - Negative keyword match types matter — "free" as phrase negative blocks "free trial" but not "trial free download" - Create a shared negative keyword list — apply learnings across campaigns automatically - Search term "other" category is hidden queries — if it's significant %, request detailed report from rep or use scripts ## Conversion Tracking Errors - Last-click attribution hides assist value — at minimum, compare with data-driven attribution - Counting "All conversions" inflates ROAS — filter to primary conversion action for true performance - Phone call conversions need duration minimums — 60 seconds minimum filters spam and misdials - Micro-conversions (email signups) have different values than purchases — set values proportionally - Cross-device conversions are modeled, not tracked — factor uncertainty into ROAS calculations ## Scaling Paid Search - Search volume has a ceiling — unlike social, you can't pay to reach more people than are searching - Impression Share shows headroom — if IS is 90%+, growth requires new keywords, not more budget - Diminishing returns are real — CPAs increase 20-40% when scaling past optimal volume. Know your efficiency/volume tradeoff - Bing Ads imports Google campaigns directly — 10-15% extra volume at lower CPCs, minimal extra work - International expansion multiplies complexity — separate accounts per market, don't just add countries to existing campaigns ## Platform Automation - Auto-applied recommendations are opt-out, not opt-in — disable recommendations that conflict with strategy - Smart campaigns hide too much data — use regular campaigns for control and learning - Performance Max cannibalizes branded search — exclude brand terms or track incrementality carefully - Scripts automate repetitive tasks — bid adjustments, budget pacing, negative keyword mining run automatically - Rules-based automation is fragile — "if CTR < 2%, pause" kills potentially good ads too early.
