SEO vs Ads: How to Split Your Ecommerce Budget
In Brief
SEO versus ads is not a channel choice. It is a budget split. A store in its first six months puts roughly 70 to 80 percent of the money into paid campaigns and the rest into technical fixes and category copy. Once organic sessions climb past about 5,000 a month, that ratio starts to reverse. Two numbers settle the argument: customer acquisition cost per channel and customer lifetime value. Pause ads for ten days and see how much revenue survives. That number is your real answer.
A home textiles brand spent 45,000 TL a month on ads last season and turned over 180,000 TL. They froze the budget for two weeks. Revenue dropped to 22,000 TL. The gap showed exactly how much the brand sold on its own, which was almost nothing.
Over the same period a small crafts supplier pulled 14,000 sessions a month from organic search while spending only 8,000 TL on ads. Its revenue was lower. Its net margin was clearly higher, because no click cost was riding on top of every order. Both stores got the same question wrong, from opposite directions.
The useful version of the question sounds like this: how should this month's money be split so that both the quarter's cash flow and next year's acquisition cost improve together? The sections below build that ratio around your store's age, category and measurement setup.
What SEO actually buys you
SEO is not a traffic channel. It is asset construction. The money does not go into clicks, it goes into something permanently attached to the site: a category page that loads faster, a sizing guide nobody has to write again, product data marked up correctly. Those assets keep working on the day you switch the ad account off.
Backlinko's click-through study found that the first organic result on Google earns an average 27.6 percent CTR, while position two drops to 15.8 percent and position three to 11 percent. Translated into practice: at identical search volume, rank one pulls close to two and a half times the visitors of rank three. Moving up a single position can do what a 20 percent ad budget increase does, without the invoice.
Set a realistic timeline
On a brand new domain the first meaningful organic movement usually shows up after month four. In crowded categories such as phone accessories, cosmetics and sportswear it stretches to nine or twelve months. Starting SEO during a cash squeeze and cutting it in month three burns the money twice. Commit to twelve months or do not start.
The invoice items nobody counts
SEO is not free, the bill just lands somewhere else. The genuine monthly line items look like this:
- Content production: category descriptions, comparison pieces and how-to guides, typically 8,000 to 20,000 TL a month.
- Technical work: image weights, server response time, fixing layout that shifts on mobile.
- Link earning: natural references from trade publications and supplier pages. Our guide to earning backlinks walks through how that is done without buying anything.
- Measurement and cleanup: clearing coverage errors in Google Search Console and tracking click loss query by query.
Add those items up and divide by that month's organic orders. The result is SEO's own acquisition cost. In year one it usually looks worse than paid, which scares people off. In year two the same content keeps selling without new spend and the number falls fast. What you are really paying for is not traffic, it is traffic that repeats.
One warning. The least productive form of SEO investment is four blog posts a month on topics nobody searches for. Open the Performance report in Search Console and list the queries sitting at an average position between 8 and 20. Those are searches that already reached your door and failed to get in. That list is where the first slice of budget belongs.
What ads fix, and what they never will
The one enormous advantage of paid media is speed. Build a campaign in the morning, take the first order that evening. When you need to test a new product line, catch the opening of a season or clear 400 units sitting in the warehouse, a six month SEO calendar is useless to you.
The second advantage is measurability. Inside Google Ads and Meta Ads you see the return on every line of spend, broken down by campaign, audience and creative. WordStream's industry benchmarks reported an average cost per click of roughly one to two dollars for ecommerce and a conversion rate near 2.81 percent. In Turkey the absolute figures move with the exchange rate and category competition, though the relative shape of those numbers holds up well.
Where paid genuinely wins
- Product validation: spend 5,000 TL over fifteen days and learn which colour and which size nobody wants.
- Bringing back cart abandoners. Remarketing is normally the cheapest line in the whole account.
- Defending your own brand searches when a competitor bids on your name.
- Short windows like discount week in November, when volume quadruples for a few days.
- Creating demand from zero in a new city or a brand new product category.
The ten day shutdown test
Pick a quiet Friday morning, well away from campaign season, pause everything and wait ten days. Whatever revenue survives is your actual brand. If it sits below 20 percent, paid media is not a growth channel for you, it is life support. Run the test twice a year and write the result down somewhere you will find it again.
What ads cannot fix is the cost curve. Competition pushes clicks up, and holding the same revenue costs a little more each month. That climb is hard to notice unless you calculate ROAS with returns and shipping inside the formula, because revenue keeps growing while profit quietly evaporates. Our breakdown of Google Ads against Meta Ads shows which platform stays cheaper for which product type.
Splitting the budget by the age of the business
There is no single correct ratio, but there are three stages. The table below shows a typical split for a store with 60,000 TL a month to spend.
| Stage | Paid | SEO and content | Split of 60,000 TL | The real job in that period |
|---|---|---|---|---|
| 0 to 6 months | 75 percent | 25 percent | 45,000 TL / 15,000 TL | Technical base, first 20 category pages, clean product data |
| 6 to 18 months | 55 percent | 45 percent | 33,000 TL / 27,000 TL | Comparison content, conversion testing |
| 18 months and beyond | 40 percent | 60 percent | 24,000 TL / 36,000 TL | Brand demand, email list, repeat purchase |
In the first stage the goal is data, not orders. A 45,000 TL ad budget teaches you which product sells at which price, where the return rate explodes and what the average basket really looks like. Without that, any SEO content you write is a blind guess. Meanwhile the 15,000 TL SEO slice goes into plumbing rather than prose: site speed, category structure, making filtered pages indexable.
Stage two changes the game. Organic traffic gives you room to be selective with paid. Hand generic category searches over to organic and push the ad budget toward high margin products and remarketing. Since both channels now land in the same cart, the biggest gains move to conversion. Growing the budget without applying the practical ways to lift conversion rate is like carrying water in a bucket with a hole in it.
In stage three, narrow the role of paid instead of killing it. Keep seasonal launches, stock clearance and brand defence. Send the rest toward widening organic coverage and growing the email and SMS list. Stores that reach this point usually see repeat customers pass a third of total revenue, and marketing shifts from chasing revenue to protecting margin.
The same money, two ways: a twelve month example
The table below is a model, not data from a real store. Its purpose is to show where two budget decisions land after twelve months. Both scenarios assume 60,000 TL a month, an average basket of 900 TL and a 40 percent gross margin.
| Line | Scenario A: all paid | Scenario B: staged split |
|---|---|---|
| Month 1 ad spend | 60,000 TL | 45,000 TL |
| Month 12 ad spend | 60,000 TL | 30,000 TL |
| Month 12 organic sessions | around 900 | around 7,500 |
| Month 12 total orders | 140 | 165 |
| Month 12 marketing cost per order | 429 TL | 364 TL |
| Revenue surviving if ads stop | 8 percent | 34 percent |
Scenario A looks better for the first six months. More spend, more orders. From month nine the cost per click starts climbing and the same 60,000 TL buys fewer visitors. Order volume flattens while cost rises, so the margin thins.
Scenario B falls behind early. Around month seven organic sessions start compounding, and even with the ad budget cut in half the order count catches up with A. By month twelve the real difference is not in order volume, it is in cost per order and in risk. If the ad account gets suspended one morning, the store in scenario A loses 92 percent of its revenue overnight.
Building your own version of this table needs three numbers: monthly marketing spend, total orders that month, and the share of orders that came from organic. Enter one row per month in a spreadsheet. After six months the curve explains itself and the argument ends.
Your category and marketplace dependency change the answer
General ratios only get you so far. How competitive your category is, and how much of your revenue arrives through a marketplace, will shift the split considerably.
When more than half your revenue comes from Trendyol and Hepsiburada
Here your own domain has close to zero organic strength and the commission rate decides your margin. The priority is moving marketplace buyers onto your own channel. A printed card in the parcel, a discount code that only works on your site and a properly built email flow will do more than an extra 20,000 TL of monthly ad spend. On your own store side, the Tecof ecommerce platform lets you run marketplace integrations from one panel while keeping stock and pricing rules separate for each channel.
When you sell in a highly competitive category
In electronics, cosmetics and fashion, ranking for generic terms takes years. Spend the SEO budget on long, high intent searches instead: compatibility questions, sizing and care guides, model comparisons. On the paid side, high click costs mean broad targeting is a trap, so build separate campaigns per product group. Running 300 products in one campaign lets your weak sellers eat the budget your strong ones earned.
When your market is narrow
In small markets such as handmade soap, collectible vinyl or climbing gear the equation tilts toward SEO. Search volume is low, but so is competition. Reaching page one in three months is realistic, and that page keeps selling for years. A 60 percent SEO and 40 percent paid split makes sense from year one for this profile, with the ad budget aimed entirely at remarketing and lookalike audiences.
Boutique production and high basket values
Where order counts are low and basket values are high, a single organic visitor is worth real money. Furniture, jewellery and made-to-order goods pull buyers who research for weeks. Case stories, material and care content and an honest pricing page become your best selling pages. You can see how that structure gets built on our solution page for growing ecommerce brands.
Without proper measurement the debate goes nowhere
Splitting a budget requires knowing which sale came from where. In a large share of Turkish stores that data is either missing or collected incorrectly. Close the gap in three steps.
Get channel attribution right
In Google Analytics 4, open the Traffic acquisition view under Reports and separate organic search, paid search, social and direct by revenue. If your email and SMS links carry no utm tags, those orders show up as direct traffic and quietly understate what paid actually contributed. Write your tagging convention into a document so everyone who builds a campaign uses the same format.
Handle KVKK and IYS from the start
Visitors who decline cookie consent never enter your measurement, which makes the design of the consent banner a measurement decision as much as a legal one. Keep the wording plain and do not bury the decline option. On the email and SMS side, sending to lists without an IYS record creates both legal exposure and delivery loss. Collect permission at the point of order and store its origin, because what gets audited is not the consent itself but where it came from.
Read Search Console and your ad panel side by side
When the same query appears in both organic and paid, the two channels may be eating each other. List the queries ranking above position three in Search Console, then check what you spend on those same terms. If you already own the top organic slot, part of that spend is wasted. Repeat the comparison quarterly. Finding 10 to 15 percent of slack in a single pass is a common outcome.
Once measurement is in place the whole discussion gets simpler. You hold an acquisition cost per channel, so you read a number instead of trading opinions. From that point the budget fight turns into a reporting habit.
A ninety day rollout calendar
To start today, run the sequence in this order.
Weeks 1 and 2: map where you stand
Put the last twelve months of marketing spend, order count and organic sessions into one spreadsheet. Then schedule the ten day shutdown test. In the same week, export every Search Console query ranking between position 8 and 20. That export is your content plan for the quarter.
Weeks 3 and 4: take the easy wins
Update the category pages behind the first ten queries on that list. Title, opening paragraph and product ordering is enough, and no new pages. On the paid side, pause broadly targeted campaigns and move that budget onto products that actually sold in the last thirty days. Those two moves usually show up on the very next invoice.
Month 2: build the structure
Publish one buying guide or comparison piece per main category, set a target of four pages a month and hold it for six months. Move remarketing into its own budget line so cold audience costs stop hiding it. Test exactly one change in the checkout or shipping step. Change two things at once and you will never learn which one worked.
Month 3: recalculate the ratio
At the end of month three, work out acquisition cost per channel again. If organic orders now exceed 15 percent of the total, shift a 10 percent slice of the ad budget into content and technical work. If they do not, hold the split and question the quality of the content rather than the size of the budget. The worst move after a three month trial is to abandon both channels half finished.
There is one job for tomorrow morning: open a spreadsheet and write the last three months of ad spend next to the number of organic orders. That is the first honest number you will hold, and every decision after it gets built on top.
Frequently Asked Questions
Should I start with SEO or with ads?
If you have no traffic at all, start with ads. What you need in the first months is not revenue but data on which product holds at which price, and paid gets you that fastest. Lay the technical groundwork for SEO in the same period, but hold off on content production until the product picture is clear.
When will I see the first SEO results?
On a new domain, meaningful movement begins after month four. In competitive categories it takes nine to twelve months. An older site responds faster to technical fixes, where ranking changes sometimes appear within six weeks.
Can I cut ads completely?
Not advisable even with strong organic traffic. Competitors can bid on your brand terms, you will miss seasonal volume peaks, and you lose the fast channel you need for testing new products. Shrink the budget instead of closing the channel.
Can I do both on 15,000 TL a month?
You can, but do not split it evenly. At that scale, 12,000 TL on ads and 3,000 TL on technical improvements works. Produce content with your own team. Halving the budget across two channels leaves you under the threshold on both and delivers nothing from either.
I sell on marketplaces, do I still need SEO on my own site?
Yes. A marketplace listing builds no authority for your domain and gives you no say over commission rates. Organic traffic on your own store means commission free sales and a direct customer relationship. Both channels can run together, and they work best when one feeds the other.
Is AI search killing SEO?
It is not killing it, it is changing the shape of it. Pages cited as sources still receive traffic, and the intent behind those clicks tends to be sharper. The work is to add short sections that answer the question directly on product and guide pages, and to keep technical data readable in table form.
What counts as a good ROAS?
There is no universal threshold, it depends on your margin. On a product with a 40 percent gross margin, paid stops making money once ROAS falls under about 2.5. Put returns and shipping into the calculation as well, otherwise a campaign that looks profitable on paper posts a loss at the till.
Agency or in-house team for SEO?
For the first year, buying technical consulting and producing content internally is the most efficient combination. Nobody explains your product better than you do. Measure an agency by pages published and technical errors closed, not by how many reports arrive each month.
How do I split spend between Google Ads and Meta Ads?
Google leads where demand already exists; Meta leads where demand has to be created and the product sells visually. Open at a 60 to 40 split, then shift after thirty days based on cost per order. Because of currency movement, judge the budget by cost per order rather than by the TL figure alone.
How much content is enough?
Coverage matters more than volume. One buying guide and one comparison piece for each main category, then a dedicated page for each question customers keep asking. For most stores, 25 to 40 pages in the first year does the job.
