Turkish grammar breaks keyword research before anyone writes a page
Turkish attaches meaning to the end of words instead of using separate prepositions, so one concept appears in search as a long tail of inflected forms: the bare noun, the possessive, the plural, the plural possessive, the locative and combinations of those with the next word in the phrase. Research tools treat each form as a separate keyword with its own volume, which makes every individual term look small and pushes inexperienced planners toward the wrong conclusion about what people want. Demand that looks marginal in a spreadsheet is often a single intent split across six spellings.
The same morphology decides how a page should be written. Stuffing every inflection into copy produces text a native reader immediately recognises as machine assembled, and it is now easier for engines to detect than it used to be. The better approach is one clean topic per page with the natural forms appearing where a person would use them, supported by headings that answer the actual question. Ask a prospective agency how they group inflected variants into topics. A firm that cannot explain its grouping logic is going to hand you a content plan with the same page written four times.
The dotted and dotless i that silently corrupts a site
Turkish has two distinct letters that look like the Latin i, and lowercase and uppercase conversion follows different rules than in English. Code that lowercases text without specifying a locale will turn one letter into the other, and every system downstream inherits the error: slugs, canonical tags, internal search, redirect maps, structured data and tracking parameters. The damage is quiet, because the page still renders. It shows up as two URLs for one product, a canonical pointing at a page that returns an error, or a filter that returns nothing for a common query.
Alongside that, users frequently type without any special characters at all, replacing the accented and dotted letters with plain ones. Your site needs to resolve both forms to a single canonical page rather than creating duplicates. This is a boring technical audit item and it is regularly the highest value fix on a Turkish website, so ask whether a prospective partner has a specific check for it. If the answer is a generic technical audit checklist copied from an English blog, the answer is no.
Marketplaces already own the transaction queries
For most physical products, the top of the results page belongs to large domestic marketplaces, and a brand site trying to outrank them on a bare product query is spending money on a fight it will not win. This is not a reason to skip search. It is a reason to move the target. The winnable territory is everything upstream and sideways: comparison, sizing, compatibility, maintenance, regulation, warranty and the questions that appear right before a purchase decision. It also includes brand plus product queries, where you should absolutely outrank a reseller listing your own goods.
The same logic applies to services. Aggregators and lead generation sites occupy many commercial terms, and the realistic goal for a mid sized service business is to own a narrower, better qualified set of queries rather than to appear once on a crowded page. A partner willing to say this at the proposal stage is more valuable than one who promises the headline term.
District level intent is what makes local search in Istanbul different
This is a metropolitan area larger than many countries, split by water and by traffic, and people search accordingly. A customer in Kadikoy looking for a service will not travel to Levent for it, and the query reflects that. Map results and local packs react strongly to proximity, so a single office address plus a list of districts in the footer produces neither rankings nor enquiries. Businesses with several branches need each one verified and maintained as its own entity with its own hours, photographs and reviews, and businesses with one location need to be honest about the catchment they can actually serve.
The trap is the mirror image of the marketplace problem: generating a page per neighbourhood with the name swapped and nothing else changed. Those pages used to rank and now dilute a site. If they genuinely serve a district, they need something specific to say about serving it, and if they do not, one well built location page plus a properly maintained map profile will outperform fifty thin ones.
Export work is a separate discipline sold under the same name
A large share of local agencies also run campaigns aimed at buyers abroad, in English, German, Arabic or Russian, for manufacturers, clinics, hotels and software firms selling outside the country. That work has almost nothing in common with domestic search beyond the tooling: different competitors, different link markets, different editorial standards and different conversion paths. Firms that are good at one are often mediocre at the other, and both are advertised on the same website.
So make your mandate explicit and ask for evidence that matches it. If you need visibility abroad, ask who writes in the target language and whether they are a native writer or a translator, then read something they published. If you need domestic visibility, ask for results in a sector with comparable competition rather than a case study from an uncontested niche.
Consent, tracking and the reporting you will actually receive
Data protection obligations apply to analytics and advertising tags, and consent handling directly affects how much of your traffic is measured. A site with a poorly implemented consent layer will report a distorted picture, usually understating organic performance, and that distortion then drives budget decisions. Fixing the measurement layer is frequently the precondition for any sensible conversation about results.
Ownership is the other half of measurement. Every property, container, ad account and registrar record should carry your company's own address, with the supplier added as a user, and the console property should be verified before the first invoice so a baseline exists that nobody can dispute in month six. Resistance to this is never technical. It is a negotiating position, and it is being taken at your expense.
Turning a long list into three comparable proposals
Give three firms an identical page: what you sell, to whom, in which languages, what has already been attempted, and what a good result looks like in money. Then weigh what each of them wanted to know before replying. The signals that matter are whether anyone raised the marketplace problem unprompted, whether anyone asked how much developer time you can actually release, and whether anyone was willing to say that a part of your brief should not be funded.
Ask for named staffing rather than a team page, a stated response time, and a monthly report that leads with enquiries and revenue rather than rankings. Ask what they would cut first at half the budget. Firms that answer that quickly and specifically have a real model of what drives results, and firms that hesitate are selling activity.
Where search sits next to everything else
Very few of these programmes succeed in isolation, because rankings expose weaknesses in the site they land on. If the underlying build is slow or the templates fight the content plan, the sensible sequence is to fix the platform first, and the local development companies are worth reviewing for that. Where demand needs to be created rather than captured, the wider digital marketing teams in the same market handle the paid and social side of the same funnel.
Before judging a local shortlist it helps to see how firms in other places frame the same service, which is what the category overview is for. With three names left, matched proposals put scope, staffing and accountability next to each other instead of leaving you to compare presentations.
